Interface ObjectHandler

All Known Implementing Classes:

EntityHandler, LiteralHandler, ResourceHandler, UriHandler, VoidHandler

public interface ObjectHandler

The interface for the internal ObjectHandler. The handler will create the RDFNode from the object passed to the setter method, and will create the object to be returned for the getter method. In general X.equals( parseObject( createRDFNode( X ))) should hold true as should X.equals( createRDFNode( parseObject( X ))).
