Detailed Description

Mock thread system. This can create mutexes that do no locking, condvars that do no waiting, and can't create threads. Trying to create a thread will result in a fatal error.

Member Function Documentation

virtual ThreadId* net_instaweb::NullThreadSystem::GetThreadId ( ) const

virtual

Returns an object holding the current thread ID. The resultant object must be freed by the caller.

Implements net_instaweb::ThreadSystem.

virtual NullCondvarCapableMutex* net_instaweb::NullThreadSystem::NewMutex ( )

virtual

Makes a new mutex for this system.

See also CondvarCapableMutex::NewCondvar.

Implements net_instaweb::ThreadSystem.

virtual RWLock* net_instaweb::NullThreadSystem::NewRWLock ( )

virtual

This lock will provide following guarantee -

• Reader reentrant safe.
• Writer Priority, this ensures no writer starvation.

Implements net_instaweb::ThreadSystem.

virtual Timer* net_instaweb::NullThreadSystem::NewTimer ( )

virtual

Creates and returns a real-time timer. Caller is responsible for deleting.

Todo:

TODO(jmarantz): consider removing this and controlling timers separately.

Implements net_instaweb::ThreadSystem.
