itk::MetaDataDictionary Class Reference

#include <itkMetaDataDictionary.h>

Detailed Description

Provides a mechanism for storing a collection of arbitrary data types.

Author
Hans J. Johnson

The MetaDataDictionary, along with the MetaDataObject derived template classes, is designed to provide a mechanism for storing a collection of arbitrary data types. The main motivation for such a collection is to associate arbitrary data elements with itk DataObjects.

The MetaDataDictionary implements shallow copying with copy on write behavior. When a copy of this class is created, the new copy will be shared with the old copy via C++11 shared pointers. When a non-constant operation is done, if the dictionary is not unique to this object, then a deep copy is performed. This make is very cheap to create multiple copies of the same dictionary if they are never modified.
