Constructor Detail

RemoteTransformationsGraph

public RemoteTransformationsGraph(IManager iManager,
                                  String remoteGraphEndpoint)
                           throws Exception

Instantiates the RemoteTransformationsGraph.

Parameters:

iManager - The IManager from which the graph will use to find information about transformationUnit programs.

remoteGraphEndpoint - The endpoind reference of the remote graph.

Throws:

Exception - If the service call could not be created.

Description copied from interface: TransformationsGraph

Finds applicable Transformation Units from the sourceContentType to the targetContentType.

Specified by:

findApplicableTransformationUnits in interface TransformationsGraph

Parameters:

sourceContentType - The ContentType of the source DataElement.

targetContentType - The ContentType of the target DataElement.

createAndPublishCompositeTP - If true then a new composite TransformationProgram is created and published if no available TransformationProgram exists.

Returns:

The available TransformationUnits.
