Class WriteBlockedGraph

java.lang.Object

java.util.AbstractCollection<Triple>

org.apache.clerezza.implementation.graph.AbstractGraph

org.apache.clerezza.implementation.graph.WriteBlockedGraph

All Implemented Interfaces:

Iterable<Triple>, Collection<Triple>, Graph

public class WriteBlockedGraph
extends AbstractGraph
implements Graph

This is a wrapper object for Graph. If SecurityManger is not null TcManager checks the TcPermission. If read-only permissions are set this wrapper is used instead of Graph and throws exceptions when add or remove methods are called.
