Description copied from interface: MGraph

Returns the graph

Specified by:

getGraph in interface MGraph

Returns:

graph

getLock

public ReadWriteLock getLock()

Description copied from interface: LockableMGraph

The lock provided by this methods allows to create read- and write-locks that span individual method calls. Having a read locks prevents other threads from writing to this MGraph, having a write-lock prevents other threads from reading and writing.
