Detailed Description

Standard Exceptions

Any operation can can throw one of the following "standard exceptions" unless it indicates the opposite:

Operations that throw other exceptions will document them explicitly.

As a general rule constructors may only throw dds::core::Error. Destructors never throw, even in case of error.

Note that any operation can throw C++ standard exceptions such as std::bad_alloc.

Catching exceptions

The class dds::core::Exception is the abstract base class for all DDS exceptions. All concrete exceptions inherit also from subclasses of std::exception, so when you need to catch an exception you have flexibility on the level of detail you need. For example, if you are setting the DomainParticipant QoS:

try {
my_participant.qos(my_participant_qos);
} catch (const dds::core::InconsistentPolicyError& ipe) {
// catch a specific exception (documented in DomainParticipant::qos())
} catch (const std::exception& ex) {
// catch any other exception here, including other DDS exceptions
}
Indicates that the application specified a set of QoS policies that are not consistent with each othe...
