Detailed Description

template<typename MetaDataObjectType>
class itk::MetaDataObject< MetaDataObjectType >

Allows arbitrary data types to be stored as MetaDataObjectBase types, and to be stored in a MetaDataDictionary.

Author
Hans J. Johnson

The MetaDataObject class is a templated class that is a specialization of the MetaDataObjectBase type. This class allows arbitrary data types to be stored as MetaDataObjectBase types, and to be stored in a MetaDataDictionary.

Any class or built in type that has valid copy constructor and operator= can be wrapped directly with this simple template type.

Classes or built in types that do not have valid copy constructors or operator= implemented will have to implement those functions by deriving from MetaDataObject<MetaDataObjectType> and redefining the copy constructor and initializing constructor and the Get/Set functions to work around those deficiencies.

The default implementation prints uses the MetaDataObjectType's Print or operator<< if available. Otherwise, it prints string "[UNKNOWN PRINT CHARACTERISTICS]".
