Class ResettableFieldHandler<T,E extends FieldUpdateEvent<T>,R extends ReflectionFormBuilder,C extends Component>

java.lang.Object

de.richtercloud.reflection.form.builder.fieldhandler.ResettableFieldHandler<T,E,R,C>

Type Parameters:

T - the type of field to handle

E - the type of field events to handle

R - the type of reflection form builder to use

C - the type of component to produce

All Implemented Interfaces:

ComponentHandler<C>, FieldHandler<T,E,R,C>

Direct Known Subclasses:

MappingFieldHandler, NumberFieldHandler

public abstract class ResettableFieldHandler<T,E extends FieldUpdateEvent<T>,R extends ReflectionFormBuilder,C extends Component>
extends Object
implements FieldHandler<T,E,R,C>

Provides reset functionality by making FieldHandler.handle(java.lang.reflect.Field, java.lang.Object, de.richtercloud.reflection.form.builder.fieldhandler.FieldUpdateListener, de.richtercloud.reflection.form.builder.ReflectionFormBuilder) final and enforcing implementation in helper handle0(java.lang.reflect.Field, java.lang.Object, de.richtercloud.reflection.form.builder.fieldhandler.FieldUpdateListener, de.richtercloud.reflection.form.builder.ReflectionFormBuilder).
