getPropertyPointer
Description copied from class:PropertyOwnerPointer
Get a PropertyPointer for this PropertyOwnerPointer.- Specified by:
getPropertyPointer
in classPropertyOwnerPointer
- Returns:
- PropertyPointer
-
createNodeIterator
Description copied from class:PropertyOwnerPointer
Create a NodeIterator.- Overrides:
createNodeIterator
in classPropertyOwnerPointer
- Parameters:
property
- property namereverse
- whether to iterate in reversestartWith
- first pointer to return- Returns:
- NodeIterator
-
attributeIterator
Description copied from class:NodePointer
Returns a NodeIterator that iterates over all attributes of the current node matching the supplied node name (could have a wildcard). May return null if the object does not support the attributes.- Overrides:
attributeIterator
in classPropertyOwnerPointer
- Parameters:
name
- the attribute name to test- Returns:

-
getName
Description copied from class:NodePointer
Returns the name of this node. Can be null.- Specified by:
getName
