#include <rtt/BufferPort.hpp>
Inherits RTT::BufferPortBase< T >.
Use connection() to access the buffer. If the port is not connected, connection() returns null.
| T | The type of the data of the buffer. |
Definition at line 237 of file BufferPort.hpp.

| This enum classifies if a port is inbound outbound or both. | |
| enum | ConnectionModel { Buffered, Data } |
| This enum classifies the kind of data connections that are available through ports: buffered or data. | |
