ossimElevCellHandler * ossimElevCellHandlerFactory::create ( const ossimString &  ) const

virtual

METHOD: instance() For accessing static singleton instance of concrete factory. The derived class implementation of this method invokes the factory's private constructor. MUST BE PROVIDED BY CONCRETE DERIVED CLASS as follows:

static <ossimFactoryBase-derived class>* instance();

PURE VIRTUAL METHODS: create(string), create(keywordlist, prefix)

Attempts to create an instance of the Product given a string or keywordlist. It is up to the concrete factory implementation to decide how to interpret string. It could conceivably represent a "magic number" specification of a product (such as the class name). Or, it could be a filename that the factory must open to decide which product to instantiate. The derived factory can also define other create methods following the model used here.

Returns successfully constructed product or NULL.

Implements ossimFactoryBase< ossimElevCellHandler >.
