Detailed Description

A lock listener is notified whenever a thread is about to wait on a lock, and when a thread is about to release a lock.

This class is for internal use by the platform-related plug-ins. Clients outside of the base platform should not reference or subclass this class.

Member Function Documentation

◆ AboutToRelease()

virtual void berry::LockListener::AboutToRelease ( )

Notification that a thread is about to release a lock.

This default implementation does nothing. Subclasses may override.

Definition at line 65 of file berryLockListener.h.

◆ AboutToWait()

virtual bool berry::LockListener::AboutToWait ( Poco::Thread *  lockOwner)

Notification that a thread is about to block on an attempt to acquire a lock. Returns whether the thread should be granted immediate access to the lock.

This default implementation always returns false. Subclasses may override.

lockOwnerthe thread that currently owns the lock this thread is waiting for, or null if unknown.
true if the thread should be granted immediate access, and false if it should wait for the lock to be available

Definition at line 55 of file berryLockListener.h.

◆ IsLockOwnerThread()

bool berry::LockListener::IsLockOwnerThread ( ) const

Returns whether this thread currently owns any locks

true if this thread owns any locks, and false otherwise.
