方法详细资料

threadLocalMap

public final InternalThreadLocalMap threadLocalMap()

Returns the internal data structure that keeps the thread-local variables bound to this thread. Note that this method is for internal use only, and thus is subject to change at any time.

setThreadLocalMap

public final void setThreadLocalMap(InternalThreadLocalMap threadLocalMap)

Sets the internal data structure that keeps the thread-local variables bound to this thread. Note that this method is for internal use only, and thus is subject to change at any time.

willCleanupFastThreadLocals

@UnstableApi
public boolean willCleanupFastThreadLocals()

Returns true if FastThreadLocal.removeAll() will be called once Thread.run() completes.

willCleanupFastThreadLocals

@UnstableApi
public static boolean willCleanupFastThreadLocals(java.lang.Thread thread)

Returns true if FastThreadLocal.removeAll() will be called once Thread.run() completes.

permitBlockingCalls

public boolean permitBlockingCalls()

Query whether this thread is allowed to perform blocking calls or not. FastThreadLocalThreads are often used in event-loops, where blocking calls are forbidden in order to prevent event-loop stalls, so this method returns false by default.

Subclasses of FastThreadLocalThread can override this method if they are not meant to be used for running event-loops.

返回:

false, unless overriden by a subclass.
