Detailed Description

VariableHandleUaNode.

Class for the Variable Handle of an internal node tree element based on the BaseNode. Derived from VariableHandle.

Member Function Documentation

NodeAccessInfo * VariableHandleUaNode::getAccessInfo ( ) const
virtual

Returns the NodeAccessInfo for the Node related to the VariableHandle The NodeAccessInfo is reference counted.

The reference counter is incremented before returning the pointer. The caller is responsible to release the reference again.

Returns Null if the NodeAccessInfo is not available or the derived class does not have access to the NodeAccessInfo.

Reimplemented from VariableHandle.
