/**
 * @class   vtkTrivialConsumer
 * @brief   Consumer to consume data off of a pipeline.
 *
 * vtkTrivialConsumer caps off a pipeline so that no output data is left
 * hanging around when a pipeline executes when data is set to be released (see
 * vtkDataObject::SetGlobalReleaseDataFlag). This is intended to be used for
 * tools such as Catalyst and not end users.
