GenericIterator

public class BlockIterator

extends SubsetIterator

A class to allow iteration over the vertices in a ControlFlowGraph which are blocks, (as opposed to decisions).

Constructor Detail

BlockIterator

public BlockIterator(ControlFlowGraph graph)

Create a new BlockIterator to iterate over the block vertices in the given ControlFlowGraph.

Parameters:

graph - A ControlFlowGraph with block vertices of interest.

Method Detail

getBlock

public CFVertex getBlock()

Return the current block. This is a convenience method which hides a cast.

Returns:

the current element cast as a CFVertex.
