Class FrameWithBoxing

java.lang.Object

com.oracle.graal.truffle.FrameWithBoxing

All Implemented Interfaces:

com.oracle.truffle.api.frame.Frame, com.oracle.truffle.api.frame.MaterializedFrame, com.oracle.truffle.api.frame.VirtualFrame

public final class FrameWithBoxing
extends Object
implements com.oracle.truffle.api.frame.VirtualFrame, com.oracle.truffle.api.frame.MaterializedFrame

More efficient implementation of the Truffle frame that has no safety checks for frame accesses and therefore is much faster. Should not be used during debugging as potential misuses of the frame object would show up very late and would be hard to identify.
