Interface ExternalResourceDescription

All Superinterfaces:

Cloneable, MetaDataObject, Serializable, XMLizable

public interface ExternalResourceDescription
extends MetaDataObject

An ExternalResourceDescription object describes a resource that is loaded in the ResourceManager and may be shared between components. This object has four properties:

• A name, used to identify the resource.
• A textual description of the resource.
• A ResourceSpecifier that describes how to create the resource (for simple data resources this will be a FileResourceSpecifier that contains a URL to the data file.
• The name of a Java class that implements the specified interface and which also implements SharedResourceObject.
