Parameters:

name - is the name given to the first node

Method Detail

getPropertyPointer

public PropertyPointer getPropertyPointer()

Specified by:

getPropertyPointer in class PropertyOwnerPointer

getName

public QName getName()

Description copied from class: NodePointer

Returns the name of this node. Can be null.

Specified by:

getName in class PropertyOwnerPointer

getBaseValue

public java.lang.Object getBaseValue()

Returns the bean itself

Specified by:

getBaseValue in class NodePointer

isCollection

public boolean isCollection()

Returns false

Specified by:

isCollection in class NodePointer

getLength

public int getLength()

Returns 1.

Specified by:

getLength in class NodePointer

isLeaf

public boolean isLeaf()

Description copied from class: NodePointer

If true, this node does not have children
