beginAllBlk()Begins an enumeration of all blocks of the range. On exit from this member, the Block componenent of the Index contains the parameters of the first (non-empty) block of the range, and the Location component represents the first element (smallest global subscript) in that block. ``First block'' simply means first in the enumeration--it does not guarantee that the block contains smaller subscripts than later blocks.
If i is the loop index, the idiom for the loop is
for(i.beginAllBlk() ; i.test() ; i.nextAllBlk())
S
The member test() is inherited from LocBlocksIndex (see section 7.2).
nextAllBlk()Move to next (non-empty) block in the enumeration, updating the Block and Location components.
