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 LowLevelDescriptor createAndLinkLowLevelDescriptor(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.

cleanMapping

protected static void cleanMapping(java.lang.String uri)

getUris

protected static java.util.Set<java.lang.String> getUris(java.lang.String key)

setUris

protected static void setUris(java.lang.String key,
                              java.util.Set<java.lang.String> uris)

listUri

protected static java.util.Set<java.lang.String> listUri(Resource resource)

List uris in the resource

Parameters:

resource - a resource

Returns:

a set of uri in this resource

listUri

protected static java.util.Set<java.lang.String> listUri(Segment segment)

Lists all URI in a segment and its subsegments.

Parameters:

segment - a segment

listUri

protected static java.util.Set<java.lang.String> listUri(Resource resource,
                                                         boolean force)

Lists all URI in a resource and its subresources.

Parameters:

resource - a resource

force - if false URI in this resource will not be listed if the resource have already been processed, else they will not matter what.

Returns:

a list of all URI in this resource the last time this resource was processed

WARNING:

this function does not support cyclic resources (a resource that contains itself) if force is true

createSegmentURIFor

protected static java.lang.String createSegmentURIFor(java.lang.Object segmentContainer)

createUniqueURIFrom

protected static java.lang.String createUniqueURIFrom(Resource resource,
                                                      boolean isChild,
                                                      boolean isAnnotation)

Create a URI checking it does not already exist in the resource.

Parameters:

resource - a top container resource

isChild - if true, the uri will describe a child or subchild of this resource

isAnnotation - if true, the uri will describe a annotation on this resource

Returns:

an URI unique among all URI in the resource and its sub resources
