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. | |

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.
