This method transforms the input data to the target ContentType and stores the results to the output. In this method the service by its self discovers the TransformationProgram to use.

Parameters:

params - The input (type + value), the output, the target ContentType and a boolean that denotes if the reporting mechanism shall be enabled.

Returns:

The output value as well as the identifier of the report (if requested).

Throws:

org.gcube.common.core.faults.GCUBEFault - If an error in transformData method occurred.

This method transforms the input data to the target ContentType and stores the results to the output. The TransformationProgram which will be used by the service is indicated by the client.

Parameters:

params - The input (type + value), the output, the target ContentType, the transformation program id and a boolean that denotes if the reporting mechanism shall be enabled.

Returns:

The output value as well as the identifier of the report (if requested).

Throws:

org.gcube.common.core.faults.GCUBEFault - If an error in transformDataWithTransformationProgram method occurred.
