Class BasicFactories

Object

BasicFactories

public class BasicFactories
extends Object

Defines a common abstraction for getting the different factories. This default implementation provides support for only the most basic factories (referencing, etc.). Many methods thrown an FactoryNotFoundException in all cases, for example all methods related to GO-1 canvas objects. Those methods will be implemented later in a subclass.

Field Detail

hints

protected final Hints hints

The hints to be used for all factory creation.

Constructor Detail

BasicFactories

public BasicFactories(Map hints)

Creates a new instance of BasicFactories with the specified set of hints. The hints map should contains only the minimum set of hints, since this constructor will keep a reference to all objects found in this map.

Parameters:

hints - The hints to be used for all factory creation, or null if none.

Method Detail

getDefault

public static BasicFactories getDefault()
