getLock

public ReadWriteLock getLock()

Specified by:

getUnsecuredGraph

public org.apache.clerezza.Graph getUnsecuredGraph()

Returns the wrapped Graph if the caller has all access rights. If the caller has only the read access right, then a write-blocked Graph is returned. If the caller has neither the read nor the write access right then an AccessControlException is thrown.

Returns:

the wrapped Graph or a write-block Graph depending on the access rights of the caller.
