Class EventChunkQueue

java.lang.Object

org.jikesrvm.tuningfork.EventChunkQueue

public class EventChunkQueue
extends Object

A Queue of EventChunks.

Unlike ChunkQueue, this queue is designed to be used in uninterruptible contexts. It assumes that all EventChunks are NonMoving and externally kept alive for the GC; therefore it can mark its head and tail fields as Untraced.

TODO: consider implementing a non-blocking queue instead of using spin locks.
