Detailed Description

Determines the flow control characteristics of the DDS::FlowController.

The flow control characteristics shape the network traffic by determining how often and in what order associated asynchronous DDS::DataWriter instances are serviced and how much data they are allowed to send.

Note that these settings apply directly to the DDS::FlowController, and do not depend on the number of DDS::DataWriter instances the DDS::FlowController is servicing. For instance, the specified flow rate does not double simply because two DDS::DataWriter instances are waiting to write.

Entity:

DDS::FlowController

Properties:

RxO = N/A

Changeable = NO for DDS::FlowControllerProperty_t::scheduling_policy, YES for DDS::FlowControllerProperty_t::token_bucket. However, the special value of DDS::Duration_t::DURATION_INFINITE as DDS::FlowControllerTokenBucketProperty_t::period is strictly used to create an on-demand DDS::FlowController. The token period cannot toggle from an infinite to finite value (or vice versa). It can, however, change from one finite value to another.
