void	addListener(ExtendedModeEnablementListener listener) Adds a listener to this enablement, the listener has be informed if the availability state of a mode in respect to a dockable has changed.
void	destroy() Informs this enablement that it is no longer of any use.
boolean	isAvailable(Dockable dockable, ExtendedMode mode) Tells whether mode is available for dockable.
void	removeListener(ExtendedModeEnablementListener listener) Removes a listener from this enablement.

isAvailable

boolean isAvailable(Dockable dockable,
                    ExtendedMode mode)

Tells whether mode is available for dockable.

Parameters:

dockable - some element, not null

mode - some mode, not null

Returns:

whether the mode is available, true if mode equals ExtendedMode.NORMALIZED

addListener

void addListener(ExtendedModeEnablementListener listener)

Parameters:

listener - the new listener

removeListener

Parameters:

listener - the listener to remove

destroy
