#include <InputPort.hpp>
A component's data input port. An Orocos input port is used to receive data samples from a distant publisher. The InputPort is read() and returns true if a sample is available.
Ideally, your algorithm should not assume a certain connection policy being used from output to input. So it should work on data connections and buffer connections.

Creates a data stream from or to this port using connection-less transports. Typically, policy.transport and policy.name_id must be properly filled in such that the data stream can be set up and input and output port can find each other. You need to call this method on two ports (input and output) using the same transport and (probably) same name_id.
