Class NamedThreadFactory

java.lang.Object

org.apache.cassandra.concurrent.NamedThreadFactory

All Implemented Interfaces:

java.util.concurrent.ThreadFactory

public class NamedThreadFactory
extends java.lang.Object
implements java.util.concurrent.ThreadFactory

This class is an implementation of the ThreadFactory interface. This is useful to give Java threads meaningful names which is useful when using a tool like JConsole.

Method Detail

newThread

public java.lang.Thread newThread(java.lang.Runnable runnable)

Specified by:

newThread in interface java.util.concurrent.ThreadFactory

threadLocalDeallocator

public static java.lang.Runnable threadLocalDeallocator(java.lang.Runnable r)

Ensures that FastThreadLocal.remove() is called when the Runnable.run() method of the given Runnable instance completes to ensure cleanup of FastThreadLocal instances. This is especially important for direct byte buffers allocated locally for a thread.
