Detailed Description

Predicate that evaluates if the given DataNode's data object pointer equals a given pointer.

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

Warning: NodePredicateData holds a raw pointer to a BaseData! NodePredicateData p(mitk::BaseData::New()); will not work because the temporary smart pointer will be destroyed. Intended use is: NodePredicateData p(myDataObject); result = myDataStorage->GetSubset(p); Then work with result, do not reuse p later.

◆ ~NodePredicateData()

mitk::NodePredicateData::~NodePredicateData ( )

override

Standard Destructor.

◆ NodePredicateData()

mitk::NodePredicateData::NodePredicateData ( mitk::BaseData * d )

protected

Protected constructor, use static instantiation functions instead.

Parameters

d	Pointer to the data object to compare against.

Member Function Documentation

◆ CheckNode()

bool mitk::NodePredicateData::CheckNode ( const mitk::DataNode * node ) const

overridevirtual

Checks if the node's data object pointer equals the stored pointer.

Parameters

node	The DataNode to check.

Returns: True if node->GetData() equals the stored data object pointer.

Implements mitk::NodePredicateBase.
