类名称：Mutex
方法名：isWriteAccess

Mutex.isWriteAccess介绍

[英]Tests whether this thread has already entered the mutex in write access. If it returns true, calling writeAccess will be executed immediatelly without any other blocking. postReadAccess will be delayed until a write access runnable is over.
[中]测试此线程是否已在写访问中进入互斥锁。如果返回true，调用writeAccess将立即执行，无需任何其他阻塞。postReadAccess将被延迟，直到写入访问可运行结束。
