This functionality is not always needed, e.g. PVM manages its pack/unpack buffers internally.

Constructor.
|
|
Destructor.
|
|
Extend buffer to the given size is needed. Existing buffer contents may be lost. |
|
Utility function. To be called after unpacking a communication buffer, it checks whether the buffer is empty. If it is not (i.e. an underflow or overflow occurred), an exception is thrown. Implements cCommBuffer. |
|
Returns the buffer after packing.
|
|
Returns the size of the buffer.
|
|
Returns message length in the buffer.
|
|
Returns true if all data in buffer was used up during unpacking. Returns false if there was underflow (too much data unpacked) or still there's unpacked data in the buffer. Implements cCommBuffer. |
|
Reset buffer to an empty state.
|
|
Set message length in the buffer. Used after receiving a message and copying it to the buffer. Reimplemented in cFileCommBuffer. |
