Class ObservableLabelFeature

java.lang.Object

org.eclipse.core.databinding.observable.AbstractObservable

org.eclipse.core.databinding.observable.value.AbstractObservableValue

org.eclipse.viatra.addon.databinding.runtime.observables.ObservableLabelFeature

All Implemented Interfaces:

org.eclipse.core.databinding.observable.IObservable, org.eclipse.core.databinding.observable.value.IObservableValue

public class ObservableLabelFeature
extends org.eclipse.core.databinding.observable.value.AbstractObservableValue

An observable label feature is a computed label, that can refer to the various parameters of the match, and reacts to the corresponding model changes.

Constructor Detail

ObservableLabelFeature

public ObservableLabelFeature(IPatternMatch match,
                              java.lang.String expression,
                              java.lang.Object container)

Method Detail

getContainer

public java.lang.Object getContainer()

getMatch

public IPatternMatch getMatch()

getExpression

public java.lang.String getExpression()

calculate

protected java.lang.Object calculate()

Subclasses must override this method to provide the object's value. Any dependencies used to calculate the value must be IObservable, and implementers must use one of the interface methods tagged TrackedGetter for ComputedValue to recognize it as a dependency.

Returns:

the object's value

dispose

public void dispose()

Specified by:

dispose in interface org.eclipse.core.databinding.observable.IObservable

doGetValue

protected final java.lang.Object doGetValue()

Specified by:

doGetValue in class org.eclipse.core.databinding.observable.value.AbstractObservableValue

makeDirty

protected final void makeDirty()

isStale

public boolean isStale()

Specified by:

isStale in interface org.eclipse.core.databinding.observable.IObservable

Overrides:

isStale in class org.eclipse.core.databinding.observable.value.AbstractObservableValue

getValueType

public java.lang.Object getValueType()

hasListeners

protected boolean hasListeners()

Since:

1.1

addChangeListener

public void addChangeListener(org.eclipse.core.databinding.observable.IChangeListener listener)

Specified by:

addChangeListener in interface org.eclipse.core.databinding.observable.IObservable

Overrides:

addChangeListener in class org.eclipse.core.databinding.observable.AbstractObservable

addValueChangeListener

public void addValueChangeListener(org.eclipse.core.databinding.observable.value.IValueChangeListener listener)

Specified by:

addValueChangeListener in interface org.eclipse.core.databinding.observable.value.IObservableValue

Overrides:

addValueChangeListener in class org.eclipse.core.databinding.observable.value.AbstractObservableValue

addListener

protected void addListener(java.lang.Object arg0,
                           org.eclipse.core.databinding.observable.IObservablesListener arg1)

removeListener

protected void removeListener(java.lang.Object arg0,
                              org.eclipse.core.databinding.observable.IObservablesListener arg1)

fireEvent

protected void fireEvent(org.eclipse.core.databinding.observable.ObservableEvent arg0)

firstListenerAdded

protected void firstListenerAdded()

lastListenerRemoved

protected void lastListenerRemoved()

getRealm

public org.eclipse.core.databinding.observable.Realm getRealm()

clone

protected java.lang.Object clone()
                          throws java.lang.CloneNotSupportedException

Overrides:

clone in class java.lang.Object

Throws:

java.lang.CloneNotSupportedException
