This section lists all ECMAScript core methods and properties supported by the ECMA Expression Builder.
Lets you work with arrays.
Array()
Constructor
Array join(separator)
The elements of the array are converted to strings, and these strings are then concatenated, separated by occurrences of the separator. If no separator is provided, a single comma is used as the separator.
Array length. The length property of this Array object
reverse()
The elements of the array are rearranged so as to reverse their order. The operation is done in-place, meaning that the original array is modified.
Array sort()
The elements of this array are sorted. The sort is not necessarily stable. If comparefn is supplied, it should be a function that accepts two arguments x and y and returns a negative value if x < y, zero if x = y, or a positive value if x > y.
Array toString()
The elements of this object are converted to strings, and these strings are then concatenated, separated by comma characters. The result is the same as if the built-in join method were invoked for this object with no argument.
There is seldom a need to use the object version of Boolean in place of True/False literal values. This object is provided for completeness. It is specified in ECMA-262.
Boolean( [true/false] )
Constructor. Optionally takes either True or False as an argument.
Boolean toString()
If this Boolean value is True, then the string “true” is returned. Otherwise, this Boolean value must be false, and the string “false” is returned.
Boolean valueOf()
Returns this Boolean value.
Lets you work with dates and times.
Date()
The constructor of the Date can have various signatures. The date constructor format can accept up to seven parameters, in the following format: new Date(year,month,date,hrs,mins,secs,ms). This date must be a java.util.Date object and not an ECMAScript Date object if you intend to use it with the Identity Manager User Application workflow system.
getDate()
Returns DateFromTime(LocalTime(t)).
getDay()
Returns WeekDay(LocalTime(t)). The days of week are numbered from 0-6. The number 0 represents Sunday and 6 represents Saturday.
getFullYear()
Returns YearFromTime(LocalTime(t)).
getHours()
Returns HourFromTime(LocalTime(t)).
getMilliseconds()
Returns msFromTime(LocalTime(t)).
getMinutes()
Returns MinFromTime(LocalTime(t)).
getMonth()
Returns MonthFromTime(LocalTime(t)). The months are returned as an integer value from 0-11. The number 0 represents January and 11 represents December.
getSeconds()
Returns SecFromTime(LocalTime(t)).
getTime()
Returns a number, which is this time value. The number value is a millisecond representation of the specified Date object.
getTimezoneOffset()
Returns (t * LocalTime(t)) / msPerMinute. The difference is in minutes between (GMT) and local time.
getUTCDate()
Returns DateFromTime(t).
getUTCDay()
Returns WeekDay(t). The days of week are numbered from 0-6. The number 0 represents Sunday and 6 represents Saturday.
getUTCFullYear()
Returns YearFromTime(t). There is no getYearUTC method, so it must be used to obtain a year from a UTC Date object.
getUTCHours()
Returns HourFromTime(t).
getUTCMilliseconds()
Returns msFromTime(t).
getUTCMinutes()
Returns MinFromTime(t).
getUTCSeconds()
Returns SecFromTime(t).
getYear()
Returns YearFromTime(LocalTime(t))—1900. The function getFullYear() is preferred for nearly all purposes because it avoids the year 2000 problem.
parse(string)
Applies the ToString operator to its argument and interprets the resulting string as a date; it returns a number, the number which is a UTC time value corresponding to the date. The string is interpreted as a local time, a UTC time, or a time in some other time zone, depending on the contents of the string.
setDate(date)
Sets the day of the month, using an integer from 1 to 31, for the supplied date according to local time.
setFullYear(year[,mon[,date]])
Sets the [Value] property of this value to UTC ECMAScript.Date. Returns the value of the [Value] property of this value.
setHours(hour[,min[,sec[,ms]]])
Sets the [Value] property of this value to UTC time. Returns the value of the [Value] property of this value. When entering a value for hours, an hour value greater than 23 is added to the existing hour value, not set.
setMilliseconds(ms)
Computes UTC from argument and sets the [Value] property of this value to TimeClip(calculatedUTCtime). Returns the value of the [Value] property of this value.
setMinutes(min[,sec[,ms]])
Sets the [Value] property of this value to UTC time. Returns the value of the [Value] property of this value.
setMonth(mon[,date])
Sets the [Value] property of this value to UTC ECMAScript.Date. Returns the value of the [Value] property of this value. If the [Value] property of this exceeds 11, the [Value] property for this is added to the existing month, not set.
setSeconds(sec [, ms ] )
Sets the [Value] property of this value to UTC time. Returns the value of the [Value] property of this value.
setTime(time)
Sets the [Value] property of this value to TimeClip(time). Returns the value of the [Value] property of this value. The [Value] property of this is a millisecond value that is converted by the TimeClip(time) method.
setUTCDate(date)
Sets the [Value] property of this value to ECMAScript.Date. Returns the value of the [Value] property of this value. If the [Value] property of this exceeds 30 or 31, the [Value] of this is added to the existing date value, not set.
setUTCFullYear(year[,mon[,date]])
Sets the [Value] property of this value to ECMAScript.Date. Returns the value of the [Value] property of this value.
setUTCHours(min[,sec[,ms]])

setUTCMilliseconds(ms)
Sets the [Value] property of this value to time and returns the value of the [Value] property of this value.
setUTCMinutes(min[,sec[,ms]])
Sets the [Value] property of this value to time. Returns the value of the [Value] property of this value.
setUTCMonth(mon[,date])
Sets the [Value] property of this value to ECMAScript.Date. Returns the value of the [Value] property of this value. If the [Value] property of this exceeds 11, the [Value] property for this is added to the existing month, not set.
setUTCSeconds(sec [, ms ] )
Sets the [Value] property of this value to time. Returns the value of the [Value] property of this value.
setYear(year)
Sets the [Value] property of this value to UTC ECMAScript.Date. Returns the value of the [Value] property of this value.
toLocaleString()
Returns a string value. The contents of the string are implementation-dependent, but are intended to represent the Date in a convenient, human-readable form appropriate to the geographic or cultural locale.
toString()
Returns this string value. The contents of the string are implementation-dependent, but are intended to represent the Date in a convenient, human-readable form in the current time zone.
toUTCString()
Returns a string value. The contents of the string are implementation-dependent, but are intended to represent the Date in a convenient, human-readable form in UTC.
UTC()
Can accept a number of different arguments. The UTC function differs from the Date constructor in two ways: it returns a time value as a number, rather than creating a Date object, and it interprets the arguments in UTC rather than as local time.
valueOf()
Returns a number, which is this time value. The valueOf() function is not generic, so it generates a runtime error if the object is not a Date object.
Used to work with the Function Object.
Function Constructor. The last argument specifies the body (executable code) of a function; any preceding arguments specify formal parameters.
The value of the length property is usually an integer that indicates the “typical” number of arguments expected by the function. However, the language permits the function to be invoked with some other number of arguments. The behavior of a function when invoked on a number of arguments other than the number specified by its length property depends on the function.
String toString()
An implementation-dependent representation of the function is returned. This representation has the syntax of a FunctionDeclaration. The use and placement of whitespace, line terminators, and semicolons within the representation string is implementation-dependent.
ECMAScript provides certain “top-level” methods and properties, so-called because they are available from any context: They are not parented by any particular object.
String escape()
The escape function computes a new, URL-legal version of a string in which certain URL-illegal characters have been replaced by hexadecimal escape sequences.
eval()
When the eval function is called with one argument x, the following steps are taken:
If x is not a string value, return x.
Parse x as an ECMAScript Program. If the parse fails, generate a runtime error.
Evaluate the program from Step 2.
If Result(3) is “normal” completion after value “V”, return the value V.
Return undefined.
A special primitive value representing positive infinity.
isFinite()
Applies Number( ) to its argument, then returns false if the result is NaN (Not a Number), +*, or **; otherwise, returns True.
isNan()
Returns True if the argument evaluates to NaN (Not a Number); otherwise, returns False
NOTE:Any form of logical comparison of NaN against anything else, including itself, returns false. Use isNaN() to determine whether a variable (or a return value, etc.) is equal to NaN.
The primitive value NaN represents the set of IEEE standard Not-a-Number values.
number parseFloat()
Produces a floating-point number by interpretation of the contents of the string argument. If the string cannot be converted to a number, the special value NaN (see NaN) is returned.
number parseInt()
Produces an integer value dictated by interpretation of the contents of the string argument, according to the specified radix.
String unescape()
Computes a new version of a string value in which escape sequences that might be introduced by the escape function are replaced with the character they represent.
All of the Math object’s properties and methods are static, which means you should prepend “Math” to the property or method name in your code. For example, use “Math.PI,” not simply “PI.”

Number atan2(x,y)
Returns an implementation-dependent approximation to the arc tangent of the quotient y/x of the arguments y and x, where the signs of the arguments are used to determine the quadrant of the result. It is intentional and traditional for the two-argument arc tangent function that the argument named y be first and the argument named x be second. The result is expressed in radians and ranges from -PI to +PI. The input value x is the x-coordinate of the point. The input value y is the y-coordinate of the point.

Example:
Math.random()=0.9545176397178535
Number round(x)
Returns the number value that is closest to the argument and is equal to a mathematical integer. If two integer number values are equally close to the argument, then the result is the number value that is closer to +infinity. If the argument is already an integer, the result is the argument itself. The input value x can be any number.
Example:
Math.round(13.53) = 14
Number sin(x)
Returns an implementation-dependent approximation to the sine of the argument. The argument is expressed in radians. The input value x must be an angle measured in radians.
Number sqrt(x)
Returns an implementation-dependent approximation to the square root of the argument. The input value x must be any numeric value or expression greater than or equal to 0. If the input value x is less than zero, the string “NaN” is returned. (NaN stands for Not a Number.)
Example:
Math.sqrt(25) = 5
Number tan(x)
Returns an implementation-dependent approximation to the tangent of the argument. The argument is expressed in radians. The input value x must be an angle measured in radians.
Lets you work with numeric values. The Number object is an object wrapper for primitive numeric values.

toString()
If the radix is the number 10 or is not supplied, then this number value is given as an argument to the ToString operator; the resulting string value is returned. If the radix is supplied and is an integer from 2 to 36, but not 10, the result is a string, the choice of which is implementation-dependent. The toString function is not generic; it generates a runtime error if this value is not a Number object. Therefore, it cannot be transferred to other kinds of objects for use as a method.
valueOf()
Returns this number value. The valueOf function is not generic; it generates a runtime error if its value is not a Number object. Therefore, it cannot be transferred to other kinds of objects for use as a method.
Used to work with objects. Object is the primitive JavaScript object type. All ECMAScript objects are descended from object. That is, all ECMAScript objects have the methods defined for object.
Constructor for object.
Object toString()
When the toString method is called on an arbitrary object, the following steps are taken:
Get the [[Class]] property of this object.
Compute a string value by concatenating the three strings “[object “, Result(1), and “]”.
Return Result(2).
Object valueOf()
The valueOf method for an object usually returns the object; however, if the object is a wrapper for a host object, as might be created by the Object constructor, the contained host object should be returned.
Used to work with String Objects.
String(x)
The constructor of the string.
charAt(pos)
Returns a string containing the character at position pos in the string resulting from converting this object to a string. If there is no character at that position, the result is the empty string. The result is a string value, not a string object.
charCodeAt(pos)
Returns a number (a nonnegative integer less than 2^16) representing the Unicode code point encoding of the character at position pos in the string resulting from converting this object to a string. If there is no character at that position, the result is NaN.
fromCharCode(char0, char1, . . .)
Returns a string value containing as many characters as the number of arguments. Each argument specifies one character of the resulting string, with the first argument specifying the first character, and so on, from left to right. An argument is converted to a character by applying the operation ToUint16 and regarding the resulting 16-bit integer as the Unicode code point encoding of a character. If no arguments are supplied, the result is the empty string.
indexOf(searchString, pos)
If the given searchString appears as a substring of the result of converting this object to a string, at one or more positions that are at or to the right of the specified position, then the index of the leftmost such position is returned; otherwise, -1 is returned. If position is undefined or not supplied, 0 is assumed, in order to search all of the string.
lastIndexOf(searchString, pos)
If the given searchString appears as a substring of the result of converting this object to a string, at one or more positions that are at or to the left of the specified position, then the index of the rightmost such position is returned; otherwise, -1 is returned. If position is undefined or not supplied, the length of the string value is assumed, in order to search all of the string.
Returns the length of the String.
String match(RegExp)
Takes a regular expression object as argument. It returns an array of matches; otherwise, returns null.
String replace(RegExp, String)
Takes a regular expression and a replacement string. It returns the original string with replacements accomplished.
String search(RegExp)
Takes a regular expression as the sole arg and returns the offset of the first substring that matches, or -1 on no match.
split(separator)
Returns an Array object, into which substrings of the result of converting this object to a string have been stored. The substrings are determined by searching from left to right for occurrences of the given separator; these occurrences are not part of any substring in the returned array, but serve to divide the string value. The separator may be a string of any length.
substring(start, end)
Returns a substring of the result of converting this object to a string, starting from character position start and running to the position end of the string. If the second parameter is not present, the end position is considered the end of the string. The result is a string value, not a string object.
toLowerCase()
Returns a string equal in length to the length of the result of converting this object to a string. The result is a string value, not a string object. Every character of the result is equal to the corresponding character of the string, unless that character has a Unicode 2.0 lowercase equivalent, in which case the lowercase equivalent is used instead. The canonical Unicode 2.0 case mapping must be used, which does not depend on implementation or locale.
toString()
Returns this string value. When concerned with the placement and use of whitespace line terminators and semicolons within the representation, the string value is implementation-dependent.
toUpperCase()
Returns a string equal in length to the length of the result of converting this object to a string. The result is a string value, not a string object. Every character of the result is equal to the corresponding character of the string, unless that character has a Unicode 2.0 uppercase equivalent, in which case the uppercase equivalent is used instead. The canonical Unicode 2.0 case mapping must be used, which does not depend on implementation or locale.
valueOf()
Returns this string value. The valueOf() function is not generic, so it generates a runtime error if the object is not a String object.
