getNbWidgetBindings

public int getNbWidgetBindings()

Specified by:

getNbWidgetBindings in interface Instrument<T extends WidgetBinding<? extends Command>>

Returns:

The number of widget bindings that compose the instrument.

hasWidgetBindings

public boolean hasWidgetBindings()

Specified by:

hasWidgetBindings in interface Instrument<T extends WidgetBinding<? extends Command>>

Returns:

True: the instrument has at least one widget binding. False otherwise.

getWidgetBindings

public List<T> getWidgetBindings()

Specified by:

getWidgetBindings in interface Instrument<T extends WidgetBinding<? extends Command>>

Returns:

The widget bindings that compose the instrument. Cannot be null.

configureBindings

protected abstract void configureBindings()

Initialises the bindings of the instrument.

addBinding

public void addBinding(T binding)

Adds the given widget binding to the list of bindings of the instrument.

Parameters:

binding - The widget binding to add. If null, nothing is done.

clearEvents

public void clearEvents()

Specified by:

isActivated in interface Instrument<T extends WidgetBinding<? extends Command>>

Returns:

True if the instrument is activated.

setActivated

public void setActivated(boolean toBeActivated)

Description copied from interface: Instrument

Activates or deactivates the instrument.

Specified by:

setActivated in interface Instrument<T extends WidgetBinding<? extends Command>>
