◆ LivelinessChangedStatus()
| dds::core::status::LivelinessChangedStatus::LivelinessChangedStatus |
( |
| ) |
|
◆ alive_count()
| int32_t dds::core::status::LivelinessChangedStatus::alive_count |
( |
| ) |
const |
- Returns
- The total number of currently active DataWriters that write the Topic read by the DataReader. This count increases when a newly-matched DataWriter asserts its liveliness for the first time or when a DataWriter previously considered to be not alive reasserts its liveliness. The count decreases when a DataWriter considered alive fails to assert its liveliness and becomes not alive, whether because it was deleted normally or for some other reason.
◆ alive_count_change()
| int32_t dds::core::status::LivelinessChangedStatus::alive_count_change |
( |
| ) |
const |
- Returns
- The change in the alive_count since the last time the listener was called or the status was read.
◆ last_publication_handle()
- Returns
- Handle to the last DataWriter whose change in liveliness caused this status to change.
◆ not_alive_count()
| int32_t dds::core::status::LivelinessChangedStatus::not_alive_count |
( |
| ) |
const |
- Returns
- The total count of currently DataWriters that write the Topic read by the DataReader that are no longer asserting their liveliness. This count increases when a DataWriter considered alive fails to assert its liveliness and becomes not alive for some reason other than the normal deletion of that DataWriter. It decreases when a previously not alive DataWriter either reasserts its liveliness or is deleted normally.
◆ not_alive_count_change()
| int32_t dds::core::status::LivelinessChangedStatus::not_alive_count_change |
( |
| ) |
const |
- Returns
- The change in the not_alive_count since the last time the listener was called or the status was read.
◆ operator!=()
Compare this Value with another Value
- Parameters
-
- Returns
- true if not equal
◆ operator->() [1/2]
The operator->() is provided to be able to directly invoke functions on the delegate.
The decision to provide direct access to the delegate was motivated by the need for providing a way that was not invasive with respect to the CXXDDS API and yet would allow for vendor-specific extension. Thus vendor-specific extensions can be invoked on the Value and on all its subclasses as follows:
my_dds_value.standard_function();
my_dds_value->vendor_specific_extension();
- Returns
- a reference to delegate.
