Detailed Description

Predicate that evaluates if the given DataNodes data object pointer equals a given pointer.

NodePredicateData(NULL) returns true if a DataNode does not have a data object (e.g. ->GetData() returns NULL). This could return an unexpected number of nodes (e.g. the root node of the tree)

Warning:

NodePredicateData holds a weak pointer to a BaseData! NodePredicateData p(mitk::BaseData::New()); will not work. Intended use is: NodePredicateData p(myDataObject); result = myDataStorage->GetSubset(p); Then work with result, do not reuse p later.
