SYNOPSIS

#include <block.h>

Inherits sc::RefCount.

Inherited by sc::SCMatrixCompositeSubblockIter, sc::SCMatrixJointSubblockIter, sc::SCMatrixListSubblockIter, sc::SCMatrixNullSubblockIter, and sc::SCMatrixSimpleSubblockIter.

Public Types

enum Access { Read, Write, Accum, None }

Public Member Functions

SCMatrixSubblockIter (Access access)
The access variable should be one of Read, Write, Accum, and None, with the SCMatrixSubblockIter:: scope operator applied.
virtual void begin ()=0
Start at the beginning.
virtual int ready ()=0
Returns nonzero if there is another block.
virtual void next ()=0
Proceed to the next block.
virtual SCMatrixBlock * block ()=0
Return the current block.
Access access () const
Return the type of Access allowed for these blocks.

Detailed Description

Objects of class SCMatrixSubblockIter are used to iterate through the blocks of a matrix.

The object must be deleted before using the matrix that owns the blocks that SCMatrixSubblockIter is iterating through.
