Detailed Description

template<class T>
class bufferof< T >

A templated typed class for buffering of objects.

This operates as a fifo buffer of typed objects which are physically copied into the buffer. The objects that are buffered are accessed from allocated buffer space. As designed this may be used with multiple producer threads and one consumer thread. To use multiple consumers, one can copy the typed object from the buffer through the get pointer and then call release. The copied object can then be used safely. This is what the copy method is used for.

Parameters:
countof typed objects in the buffer.

Member Function Documentation

template<class T >
void bufferof< T >::copy ( T *  object) [inline]

Copy the next typed object from the buffer.

This blocks until an object becomes available.

Parameters:
objectpointer to copy typed object into.

Definition at line 531 of file containers.h.

Here is the call graph for this function:

template<class T >
T* bufferof< T >::get ( void  ) [inline]

Get the next typed object from the buffer.

This blocks until an object becomes available.

Returns:
pointer to next typed object from buffer.

Reimplemented from Buffer.

Definition at line 498 of file containers.h.

template<class T >
T* bufferof< T >::get ( timeout_t  timeout) [inline]

Get the next typed object from the buffer.

Parameters:
timeoutto wait when buffer is empty in milliseconds.
Returns:
pointer to next typed object in the buffer or NULL if timed out.

Reimplemented from Buffer.

Definition at line 506 of file containers.h.

template<class T >
bool bufferof< T >::get ( T *  object,
timeout_t  timeout 
) [inline]

Copy the next typed object from the buffer.

Parameters:
objectpointer to copy typed object into.
timeoutto wait when buffer is empty in milliseconds.
Returns:
true if object copied, or false if timed out.

Definition at line 540 of file containers.h.

Here is the call graph for this function:

template<class T >
bool bufferof< T >::put ( T *  object,
timeout_t  timeout 
) [inline]

Put (copy) an object into the buffer.

Parameters:
objectto copy into the buffer.
timeoutto wait if buffer is full.
Returns:
true if copied, false if timed out while full.

Definition at line 523 of file containers.h.

Here is the call graph for this function:

template<class T >
void bufferof< T >::put ( T *  object) [inline]

Put (copy) a typed object into the buffer.

This blocks while the buffer is full.

Parameters:
objectto copy into the buffer.
