java.lang.Object

com.oracle.truffle.api.nodes.Node

com.oracle.truffle.sl.nodes.controlflow.SLBreakNode

All Implemented Interfaces:

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

public final class SLBreakNode
extends SLStatementNode

Implementation of the SL break statement. We need to unwind an unknown number of interpreter frames that are between this SLBreakNode and the SLWhileNode of the loop we are breaking out. This is done by throwing an exception that is caught by the loop node.
