Method Detail

dispose

public void dispose()

Description copied from class: BooleanBinding

A default implementation of dispose() that is empty.

Specified by:

dispose in interface Binding<java.lang.Boolean>

Overrides:

dispose in class BooleanBinding

onInvalidating

protected void onInvalidating()

Description copied from class: BooleanBinding

The method onInvalidating() can be overridden by extending classes to react, if this binding becomes invalid. The default implementation is empty.

Overrides:

onInvalidating in class BooleanBinding

computeValue

protected boolean computeValue()

Description copied from class: BooleanBinding

Calculates the current value of this binding.

Classes extending BooleanBinding have to provide an implementation of computeValue.

Specified by:

computeValue in class BooleanBinding

Returns:

the current value

getDependencies

public ObservableList<ObservableValue<?>> getDependencies()

Description copied from class: BooleanBinding

A default implementation of getDependencies() that returns an empty ObservableList.

Specified by:

getDependencies in interface Binding<java.lang.Boolean>

Overrides:

getDependencies in class BooleanBinding

Returns:

an empty ObservableList
