global static fferpcore.DataTransformationService.TransformResult transform(Set<fferpcore.DataTransformationService.TransformRequest> requests)

The method takes a set of TransformRequests and performs the transformation. It yields a Transformation result which wraps all the DataResults for each TransformRequest.

Input Parameters

Return Value

This service returns a DataTransformationService.TransformResult.

global DataResult(String output, String error)

Construct a DataResult with the given output and error. If output and error are both null, an explicit null output is assumed.

Input Parameters

Return Value
