17.1.1.3.26. PartitionQosPolicy

class eprosima::fastdds::dds::PartitionQosPolicy : public eprosima::fastdds::dds::Parameter_t, public eprosima::fastdds::dds::QosPolicy

Set of strings that introduces a logical partition among the topics visible by the Publisher and Subscriber. A DataWriter within a Publisher only communicates with a DataReader in a Subscriber if (in addition to matching the Topic and having compatible QoS) the Publisher and Subscriber have a common partition name string.

The empty string (“”) is considered a valid partition that is matched with other partition names using the same rules of string matching and regular-expression matching used for any other partition name.

Note

Mutable Qos Policy
