Method Summary

Modifier and Type	Method and Description
<T> int	accepts(PropertyMetaModel<T> pmm, Class<? extends IControl<T>> controlClass) This must return a +ve value when this factory accepts the specified property; the returned value is an eagerness score.
<T,C extends IControl<T>> C	createControl(PropertyMetaModel<T> pmm, Class<C> controlClass) This MUST create all nodes necessary for a control to edit the specified item.

Method Detail

accepts

<T> int accepts(@Nonnull
                PropertyMetaModel<T> pmm,
                @Nullable
                Class<? extends IControl<T>> controlClass)

This must return a +ve value when this factory accepts the specified property; the returned value is an eagerness score. The factory returning the highest eagerness wins.

Parameters:

pmm -

controlClass - When set the control factory *must* be able to return a component which is assignment-compatible with this class type. If it cannot it MUST refuse to create the control.

Returns:

createControl

@Nonnull
<T,C extends IControl<T>> C createControl(@Nonnull
                                                   PropertyMetaModel<T> pmm,
                                                   @Nullable
                                                   Class<C> controlClass)

This MUST create all nodes necessary for a control to edit the specified item. The nodes must be added to the container; this must return a ModelBinding to bind and unbind a value to the control created.

Parameters:

pmm -

controlClass - When set the control factory *must* return a component which is assignment-compatible with this class type. When this method is called it has already (by it's accept method) told us it can, so not creating the proper type is not an option.

container -
