Specified by:

computeValue in class BooleanBinding

Returns:

the current value

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

getDependencies

public <any> getDependencies()

Description copied from class: BooleanBinding

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

Specified by:

getDependencies in interface Binding<java.lang.Boolean>

Overrides:

getDependencies in class BooleanBinding

Returns:

an empty ObservableList
