Method Detail

refresh

boolean refresh()

This method refreshes the given object. This can be anything from reloading configuration to rebuilding the internal state. An invocation of this method may be expensive and should only be invoked as needed. The implementation of this method should be thread-safe if the object itself is to be used by separate consumers at all.

Returns:

true if something has changed, false otherwise. If the implementation can not determine the change it should return true.
