Detailed Description

template<class 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 behavior of the MetaDataObject<Type>::Print() function has many plausible application dependant implementations. The default implementation prints the string "[UNKNOWN PRINT CHARACTERISTICS]" that works for all possible MetaDataObject types.

The application developer may overload the default implementation to provide a specialized Print() characteristics to produce results desirable for their application. A set of very crude Macros {NATIVE_TYPE_METADATAPRINT, ITK_OBJECT_TYPE_METADATAPRINT_1COMMA, ITK_IMAGE_TYPE_METADATAPRINT } are provided to facilitate a very simple implementation, and as an example.

Member Function Documentation

template<class MetaDataObjectType>

virtual ::itk::LightObject::Pointer itk::MetaDataObject< MetaDataObjectType >::CreateAnother

(

void

)

const [virtual]

Create an object from an instance, potentially deferring to a factory. This method allows you to create an instance of an object that is exactly the same type as the referring object. This is useful in cases where an object has been cast back to a base class.

Reimplemented from itk::LightObject.

template<class MetaDataObjectType>

virtual const std::type_info& itk::MetaDataObject< MetaDataObjectType >::GetMetaDataObjectTypeInfo

(

void

)

const [virtual]

Author:

Hans J. Johnson

The definition of this function is necessary to fulfill the interface of the MetaDataObjectBase

Returns:

A constant reference to a std::type_info object

Reimplemented from itk::MetaDataObjectBase.

template<class MetaDataObjectType>

virtual const char* itk::MetaDataObject< MetaDataObjectType >::GetMetaDataObjectTypeName

(

void

)

const [virtual]

Author:

Hans J. Johnson

The definition of this function is necessary to fulfill the interface of the MetaDataObjectBase

Returns:

A pointer to a const char array containing the unique type name.

Reimplemented from itk::MetaDataObjectBase.

template<class MetaDataObjectType>

const MetaDataObjectType& itk::MetaDataObject< MetaDataObjectType >::GetMetaDataObjectValue

(

void

)

const

Author:

Hans J. Johnson Function to return the stored value of type MetaDataObjectType.

Returns:

a constant reference to a MetaDataObjectType

template<class MetaDataObjectType>

virtual const char* itk::MetaDataObject< MetaDataObjectType >::GetNameOfClass

(

)

const [virtual]

Run-time type information (and related methods).

Reimplemented from itk::MetaDataObjectBase.

template<class MetaDataObjectType>

static Pointer itk::MetaDataObject< MetaDataObjectType >::New

(

void

)

[static]

Method for creation through the object factory.

Reimplemented from itk::LightObject.

Referenced by itk::EncapsulateMetaData().

template<class MetaDataObjectType>

virtual void itk::MetaDataObject< MetaDataObjectType >::Print

(

std::ostream &

os

)

const [virtual]

Defines the default behavior for printing out this element

Parameters:

os	An output stream

Reimplemented from itk::MetaDataObjectBase.

template<class MetaDataObjectType>

void itk::MetaDataObject< MetaDataObjectType >::SetMetaDataObjectValue

(

const MetaDataObjectType &

NewValue

)

Author:

Hans J. Johnson Function to set the stored value of type MetaDataObjectType.

Parameters:

NewValue

A constant reference to at MetaDataObjectType.
