Class RunnableQueue

java.lang.Object

com.mapr.ojai.store.impl.RunnableQueue

public class RunnableQueue
extends java.lang.Object

A queue that will manage multiple Runnables, and ensure they are executed in the sequence they are submitted. This is useful when a callback interface can keep delivering messages if they are immediately "handled" by delegating them to another thread; this supports them being executed by the same thread until the messages run out.
