Method Detail

toXml

public org.w3c.dom.Element toXml(org.w3c.dom.Node parent)
                          throws GCVException

Throws:

GCVException

checkAllowedType

public boolean checkAllowedType(int type)

Check whether or not a particular Control Value type is allowed in this collection of Control Values.

Derived classes must override this.

Specified by:

checkAllowedType in interface GCOwner

Parameters:

type - GCValue.TYPE_STRING, etc.

Returns:

true if allowed, false otherwise

_construct

protected static com.novell.nds.dirxml.engine.gcv.GCList _construct(org.w3c.dom.Element element,
                                                                    com.novell.nds.dirxml.engine.gcv.GCList list)
                                                             throws GCVException

Populate a GCDefinitions object and association GCValue objects from a DOM XML element containing the XML representation.

Typically, the DOM element would be the result of parsing the value of the DirXML-ConfigValues attribute.

Parameters:

element - DOM element

definitions - the instance to populate.

Throws:

GCVException - thrown if XML is incorrect in any way.

hasBeenModified

public boolean hasBeenModified()

Return true if this instance has been modified.

The instance is considered to have been modified if a change was made that affects the persistent representation since:

1. The instance was constructed from an XML representation.
2. resetModified() was last called

Returns:

true or false

See Also:

resetModified(), #toXML(org.w3c.dom.Node)

resetModified

public void resetModified()

Reset the modified flag for this instance such that hasBeenModified() will return false.

See Also:

hasBeenModified()

getValue

public GCValue getValue(java.lang.String name)

Get a GCValue object by name. This will do a deep search for the GCV, meaning it will look at all descendant GCVs.

Parameters:

name - the GCV name.

Returns:

GCValue object, or null if name not found.

getChildValue

public GCValue getChildValue(java.lang.String name)

Get a GCValue object that is a direct child of this instance by name.

Parameters:

name - the GCV name.

Returns:

GCValue object, or null if name not found.

appendValue

public void appendValue(GCValue value)
                 throws GCVArgumentException

Add a GCV to the end of the current list of GCVs.

Specified by:

appendValue in interface GCOwner

Parameters:

value - GCValue object to add.

Throws:

GCVArgumentException - thrown if value has the same name as a GCV already in the list.

insertValue

public void insertValue(GCValue newValue,
                        java.lang.String insertionPoint)
                 throws GCVArgumentException

Insert a GCV into the current list of GCVs.

Specified by:

insertValue in interface GCOwner

Parameters:

newValue - GCValue object to add.

insertionPoint - name of GCV in front of which newValue is to be inserted.

Throws:

GCVArgumentException - thrown if insertionPoint doesn't match the name of any GCV in the list, or if the name of newValue matches the name of a GCV already in the list.

insertValue

public void insertValue(GCValue newValue,
                        GCValue insertionPoint)
                 throws GCVArgumentException

Insert a GCV into the current list of GCVs.

Specified by:

insertValue in interface GCOwner

Parameters:

newValue - GCValue object to add.

insertionPoint - GCV in front of which newValue is to be inserted.

Throws:

GCVArgumentException - thrown if insertionPoint doesn't appear in the list, or if the name of newValue matches the name of a GCV already in the list.

replaceValue

public void replaceValue(GCValue newValue,
                         GCValue oldValue)
                  throws GCVArgumentException

Insert a GCV into the current list of GCVs.

Specified by:

replaceValue in interface GCOwner

Parameters:

newValue - GCValue object to add.

oldValue - GCV to be replaced (must not be null).

Throws:

GCVArgumentException - thrown if oldValue doesn't appear in the list, or if the name of newValue matches the name of another GCV already in the list.

removeValue

public boolean removeValue(java.lang.String name)

Remove a GCV from the list of GCVs.

Specified by:

removeValue in interface GCOwner

Parameters:

name - name of GCV to remove.

removeValue

public boolean removeValue(GCValue value)

Remove a GCV from the list of GCVs.

an Iterator instance.

shallowIterator in interface GCOwner

Returns:

an Iterator instance.
