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.

Definition at line 4312 of file processor.h.

04313                 {
04314                         return "Get the transpose of an image. Works for 2D only";
04315                 }

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 4296 of file processor.h.

04297                 {
