Detailed Description

template<class T>
class RTT::internal::LockedQueue< T >

A lock-based queue implementation to enqueue or dequeue a pointer of type T. No memory allocation is done during read or write.

Parameters

T	The pointer type to be stored in the queue. Example : LockedQueue<A*> is a queue which holds values of type A.
