Method Details

bind

public void bind(javafx.beans.value.ObservableValue<? extends T> other)

Specified by:

bind in interface javafx.beans.property.Property<T>

unbind

public void unbind()

Specified by:

unbind in interface javafx.beans.property.Property<T>

isBound

public boolean isBound()

Specified by:

isBound in interface javafx.beans.property.Property<T>

setValue

public void setValue(T value)

Specified by:

setValue in interface javafx.beans.value.WritableValue<T>

connect

protected Subscription connect()

Description copied from class: ValBase

Implementation of this method should start observing inputs. If the value of this Val may change as a result of input change, the corresponding input observer should call ValBase.invalidate() to notify observers of this Val. By the time of calling ValBase.invalidate(), the input observer must have already updated any internal state of this Val, so that a subsequent call to ValBase.computeValue() returns the current value of this Val.

Specified by:

connect in class ValBase<T>

Returns:

Subscription that can be used to stop observing inputs.

computeValue

protected T computeValue()

Specified by:

computeValue in class ValBase<T>
