Method Detail

getMinCount

public int getMinCount()

Get the minimum number of instances allowed.

Returns:

the minimum count

setMinCount

public void setMinCount(int minCount)

Set the minimum number of instances. If the passed minimum is larger than the current maximum then the maximum is adjusted.

Parameters:

minCount - the new minimum count

getMaxCount

public int getMaxCount()

Get the maximum number of instances allowed.

Returns:

the maximum count

setMaxCount

public void setMaxCount(int maxCount)

Set the maximum number of instances. If the passed maximum is larger than the current minimum then the minimum is adjusted.

Parameters:

maxCount - the new maximum count

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,
                        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(String name)

Remove a GCV from the list of GCVs.

Specified by:

removeValue in interface GCOwner

Parameters:

name - name of GCV to remove.

Returns:

true if name was found and removed, false otherwise.

removeValue

public boolean removeValue(GCValue value)

Remove a GCV from the list of GCVs.

Specified by:

removeValue in interface GCOwner

Parameters:

value - the GCV to remove.

Returns:

true if the GCV was found and removed, false otherwise.

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(Element element,
                                                                    com.novell.nds.dirxml.engine.gcv.GCList list)

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(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(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.

iterator

public Iterator iterator()

Return an Iterator instance that can be used to iterate through the list of GCVs. The iterator returned will iterate through all descendant GCValues, including those that are children of Groups.

The Iterator's next() method returns GCValue instances.

Specified by:

iterator in interface GCOwner

Returns:

an Iterator instance.

See Also:

shallowIterator()

shallowIterator

public Iterator shallowIterator()

Return an Iterator instance that can be used to iterate through the list of GCVs. The iterator returned will iterate through only GCValues that are direct children of the GCDefinitions.

The Iterator's next() method returns GCValue instances.

Specified by:

shallowIterator in interface GCOwner

Returns:

an Iterator instance.

See Also:

iterator()

isNameAllowed

public boolean isNameAllowed(String name)

Check to see if a name is allowed.

true or false

addName

public void addName(GCValue newValue)
             throws GCVArgumentException

Add a name to the defsList map. This is designed to be called from GCParent.

Specified by:

addName in interface GCOwner

Parameters:

newValue - new GCValue

Throws:

GCVArgumentException

removeName

public void removeName(GCValue oldValue)

Remove a name from the defsList map. This is designed to be called from GCParent.
