Detailed Description

Interface class for registries.

This class defines the interface for registries. A registry is a container class that contains instance of derived classes. For example, if three different derived classes exist for a given base class, the registry will contain one instance for each derived class. Using the clone mechanism, the registry may thus provide a new instance of a given derived class, depending on the type of the derived class.

The interface class requires the implementation of the following methods for all registry classes:

size(void) Number of elements in registry class

name(const int& index) Name of registered class by index

print() Print content of registry

virtual std::string GRegistry::name ( const int &  index ) const

pure virtual

Return name of registered class by index.

Parameters

[in]

index

Class index [0,...,size()-1]

Returns the name of a registered class, specified by its index in the registry.

virtual std::string GRegistry::print ( const GChatter &  chatter = NORMAL ) const

pure virtual

Print content of object.

Returns

String containing the content of the object.

Formats the content in a standard way and puts this content in a C++ string that is returned.

virtual int GRegistry::size ( void  ) const

pure virtual

Return number of classes in registry.

Returns the number of classes that have been registered in the registry.

Implemented in GModelSpatialRegistry, GModelSpectralRegistry, GModelTemporalRegistry, GCTAModelSpatialRegistry, GObservationRegistry, GModelRegistry, GWcsRegistry, and GCTAModelRadialRegistry.
