Class AnzoContextStatementImpl

java.lang.Object
  org.openrdf.model.impl.StatementImpl
      org.openrdf.model.impl.ContextStatementImpl
          org.openanzo.model.impl.AnzoContextStatementImpl

All Implemented Interfaces:

java.io.Serializable, org.openrdf.model.Statement

public class AnzoContextStatementImpl
extends org.openrdf.model.impl.ContextStatementImpl

Extension of ContextStatementImpl that adds a few extra constraints.

Hashcode is stored so that it doesn't have to be recomputed every time its needed.

Checks that all values are set on creation, and throws exception if not.

Compares context of 2 statements during equals, if both have a context set.
