Detailed Description

template<class T>
class ucommon::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.

Member Function Documentation

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

Copy the next typed object from the buffer.

This blocks until an object becomes available.

Parameters:
object pointer to copy typed object into.

Here is the call graph for this function:

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

Copy the next typed object from the buffer.

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

Here is the call graph for this function:

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

Get the next typed object from the buffer.

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

Reimplemented from ucommon::Buffer.

Definition at line 506 of file containers.h.

template<class T >
T* ucommon::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 ucommon::Buffer.

Definition at line 498 of file containers.h.

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

Put (copy) an object into the buffer.

Parameters:
object to copy into the buffer.
timeout to 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 ucommon::bufferof< T >::put ( T *  object  )  [inline]

Put (copy) a typed object into the buffer.

This blocks while the buffer is full.

Parameters:
object to copy into the buffer.
