handleFreezeCommand

protected void handleFreezeCommand(IFreezeCoordinatesProvider coordinatesProvider,
                                   boolean toggle,
                                   boolean override)

Performs freeze actions dependent on the coordinates specified by the given IFreezeCoordinatesProvider and the configuration flags. If a freeze state is already active it is checked if this state should be overriden or toggled. Otherwise the freeze state is applied.

Parameters:

coordinatesProvider - The IFreezeCoordinatesProvider to retrieve the freeze coordinates from

toggle - whether to unfreeze if the freeze layer is already in a frozen state

override - whether to override a current frozen state.

handleUnfreeze

protected void handleUnfreeze()

Unfreeze a current frozen state.
