Method Summary

Modifier and TypeMethod and Description
public void
bind(ObservableValue<? extends T> other)

Implements javafx.beans.property.Property.bind.

Create a unidirection binding for this Property.

protected T
computeValue()

Implements abstract org.reactfx.value.ValBase.computeValue.

protected Subscription
connect()

Implements abstract org.reactfx.value.ValBase.connect.

Implementation of this method should start observing inputs.

public boolean
isBound()

Implements javafx.beans.property.Property.isBound.

Can be used to check, if a Property is bound.

public void
setValue(T value)

Implements javafx.beans.value.WritableValue.setValue.

Set the wrapped value.

public void
unbind()

Implements javafx.beans.property.Property.unbind.

Remove the unidirectional binding for this Property.

Doc from javafx.beans.property.Property.bind.

Create a unidirection binding for this Property.

Note that JavaFX has all the bind calls implemented through weak listeners. This means the bound property can be garbage collected and stopped from being updated.

Implements abstract org.reactfx.value.ValBase.connect.

Doc from org.reactfx.value.ValBase.connect.

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 invalidate() to notify observers of this Val. By the time of calling invalidate(), the input observer must have already updated any internal state of this Val, so that a subsequent call to computeValue() returns the current value of this Val.

Remove the unidirectional binding for this Property. If the Property is not bound, calling this method has no effect.
