Interface BBlockNodeIterator

All Known Implementing Classes:

BBlockHirNodeIteratorImpl

public interface BBlockNodeIterator

BBlockNodIterator inteterface Basic block node iterator to traverse node in a basic block. in the order of from top to bottom, from left to right. If the basic block containes a list of subtrees, then the list is traversed from head to tail traversing each subtree.

Method Summary

IR	getNextExecutableNode() getNextExecutableNode: Get the node that refer/set data or change control flow directly.
boolean	hasNext() hasNext:
IR	next() next: Get the next node in this basic block.

Method Detail

next

public IR next()

next: Get the next node in this basic block. By repetitively invoking "next", all nodes in the basic block are traversed.

hasNext

public boolean hasNext()

hasNext:

Returns:

true if there is next node remaining in the basic block.

getNextExecutableNode

public IR getNextExecutableNode()

getNextExecutableNode: Get the node that refer/set data or change control flow directly. For what nodes refer/set data or change control flow, see { FlowUtil#isExecutable(coins.ir.IR) FlowUtil.isExecutable(coins.ir.IR)}.
