Class DFAStateNode.LoopOptimizationNode

java.lang.Object

com.oracle.truffle.api.nodes.Node

com.oracle.truffle.regex.tregex.nodes.dfa.DFAStateNode.LoopOptimizationNode

All Implemented Interfaces:

com.oracle.truffle.api.nodes.NodeInterface, Cloneable

Direct Known Subclasses:

DFAStateNode.LoopOptIndexOfAnyNode, DFAStateNode.LoopOptIndexOfStringNode

Enclosing class:

DFAStateNode

public abstract static class DFAStateNode.LoopOptimizationNode
extends com.oracle.truffle.api.nodes.Node

This node is used when all except a very small set of code points will loop back to the current DFA state. This node's DFAStateNode.LoopOptimizationNode.execute(Object, int, int) method will search for the given small set of code points in an optimized, possibly vectorized loop.
