virtual string EMAN::TransposeProcessor::get_desc (  )  const [inline, virtual]

Get the descrition of this specific processor.

This function must be overwritten by a subclass.

Returns:
The description of this processor.

Implements EMAN::Processor.

04569                         return "Get the transpose of an image. Works for 2D only";
04570                 }

virtual string EMAN::TransposeProcessor::get_name (  )  const [inline, virtual]

Get the processor's name.

Each processor is identified by a unique name.

Returns:
The processor's name.

Implements EMAN::Processor.

Definition at line 4551 of file processor.h.

References NAME.
