Class ValuePolicyModelGroup<V>

java.lang.Object
  com.guiseframework.model.AbstractModelGroup<ValueModel<V>>
      com.guiseframework.model.ValuePolicyModelGroup<V>

Type Parameters:

V - The type of value contained in the value model.

All Implemented Interfaces:

com.globalmentor.beans.GenericPropertyChangeListener<V>, ModelGroup<ValueModel<V>>, java.beans.PropertyChangeListener, java.util.EventListener

Direct Known Subclasses:

MutualExclusionPolicyModelGroup

public abstract class ValuePolicyModelGroup<V>
extends AbstractModelGroup<ValueModel<V>>
implements com.globalmentor.beans.GenericPropertyChangeListener<V>

An abstract implementation of a group of value models implementing a value policy across several models, such as mutual exclusion. When value models are added to the list, the group adds itself as a property value change listeners to the model, listening for changes in the value.

Constructor Detail

ValuePolicyModelGroup

public ValuePolicyModelGroup(ValueModel<V>... models)

Model constructor.

Parameters:

models - Zero or more models with which to initially place in the group.

Throws:

java.lang.NullPointerException - if one of the models is null.

Method Detail

addImpl

protected void addImpl(ValueModel<V> valueModel)

Actual implementation of adding a model to the group. This version adds this class instance as a listener to the model's value changing.

Overrides:

addImpl in class AbstractModelGroup<ValueModel<V>>

Parameters:

valueModel - The model to add to the group.

removeImpl

protected void removeImpl(ValueModel<V> valueModel)

Actual implementation of removing a model from the group. This version removes this class instance as a listener to the model's value changing.

Overrides:

removeImpl in class AbstractModelGroup<ValueModel<V>>

Parameters:

valueModel - The model to remove from the group.

propertyChange

public final void propertyChange(java.beans.PropertyChangeEvent propertyChangeEvent)

Called when a bound property is changed. This not-generics version calls the generic version, creating a new event if necessary. No checks are made at compile time to ensure the given event actually supports the given generic type.

Specified by:

propertyChange in interface java.beans.PropertyChangeListener

Parameters:

propertyChangeEvent - An event object describing the event source, the property that has changed, and its old and new values.
