Transformations Graph is responsible to find Transformation Units which can be used in order to perform a transformationUnit for an object, from its content type (source) to a target content type.

Method Summary

void	destroy() Destroys the graph.
ArrayList<TransformationUnit>	findAnyTransformationUnits(ContentType sourceContentType, ContentType targetContentType, boolean createAndPublishCompositeTP) Finds Transformation Units from the sourceContentType to the targetContentType.
ArrayList<TransformationUnit>	findApplicableTransformationUnits(ContentType sourceContentType, ContentType targetContentType, boolean createAndPublishCompositeTP) Finds applicable Transformation Units from the sourceContentType to the targetContentType.
ArrayList<ContentType>	findAvailableTargetContentTypes(ContentType sourceContentType) Finds the available target ContentTypes from the sourceContentType.

Method Detail

findApplicableTransformationUnits

ArrayList<TransformationUnit> findApplicableTransformationUnits(ContentType sourceContentType,
                                                                ContentType targetContentType,
                                                                boolean createAndPublishCompositeTP)

Finds applicable Transformation Units from the sourceContentType to the targetContentType.

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.

findAnyTransformationUnits

ArrayList<TransformationUnit> findAnyTransformationUnits(ContentType sourceContentType,
                                                         ContentType targetContentType,
                                                         boolean createAndPublishCompositeTP)

Finds Transformation Units from the sourceContentType to the targetContentType. Returns also generic Transformation Units.

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.

findAvailableTargetContentTypes

ArrayList<ContentType> findAvailableTargetContentTypes(ContentType sourceContentType)

Finds the available target ContentTypes from the sourceContentType.

Parameters:

sourceContentType - The ContentType of the source DataElement.

Returns:

The available target ContentTypes from the sourceContentType.

destroy

void destroy()

Destroys the graph.
