Class LowLevelDescriptorFactory

java.lang.Object
  org.ow2.weblab.core.extended.factory.LowLevelDescriptorFactory

public class LowLevelDescriptorFactory
extends java.lang.Object

This class will provide an easy and strongly recommended way to create LowLevelDescriptors.it will enable the creation of a LowLevelDescriptor having an URI compliant with the WebLabRI recommendations.
Since an LowLevelDescriptor hasn't any sense without being attached to a Resource, we only provide a method for creating LowLevelDescriptors that takes a Resource in parameter. As a result, the created LowLevelDescriptor is added to the LowLevelDescriptor List of the Resource.

Method Detail

createAndLinkLowLevelDescriptor

public static final org.ow2.weblab.core.model.LowLevelDescriptor createAndLinkLowLevelDescriptor(org.ow2.weblab.core.model.Resource res)

Method that should create and link a LowLevelDescriptor from/to a Resource. Automatically set a valid WebLabRI to the created LowLevelDescriptor using the Resource in parameter to generate an unique id. Created LowLevelDescriptor will be added to resource.

Parameters:

res - The Resource to be described by the LowLevelDescriptor.

Returns:

The LowLevelDescriptor describing res.
