Detailed Description

Attribute	Attribute Meaning
total_count	Total cumulative count the concerned DataWriter discovered a “match” with a DataReader. That is, it found a DataReader for the same Topic with a requested QoS that is compatible with that offered by the DataWriter.
total_count_change	The change in total_count since the last time the listener was called or the status was read.
last_subscription_handle	Handle to the last DataReader that matched the DataWriter causing the status to change.
current_count	The number of DataReaders currently matched to the concerned DataWriter.
current_count_change	The change in current_count since the last time the listener was called or the status was read.

The DataWriter has found a DataReader that matches the Topic and has compatible QoS or ceased to be matched with a DataReader.

Member Function Documentation

current_count()

int32_t dds::core::status::PublicationMatchedStatus::current_count

(

)

const

Returns

The number of DataReaders currently matched to the concerned DataWriter.

Definition at line 288 of file StatusImpl.hpp.

current_count_change()

int32_t dds::core::status::PublicationMatchedStatus::current_count_change

(

)

const

Returns

The change in current_count since the last time the listener was called or the status was read.

Definition at line 294 of file StatusImpl.hpp.

last_subscription_handle()

const dds::core::InstanceHandle dds::core::status::PublicationMatchedStatus::last_subscription_handle

(

)

const

Returns

Handle to the last DataReader that matched the DataWriter causing the status to change.

Definition at line 300 of file StatusImpl.hpp.

operator!=()

template<typename D >

bool dds::core::Value< D >::operator!= ( const Value< D > &  other ) const

inherited

Compare this Value with another Value

Parameters

other

Value

Returns

true if not equal

Definition at line 99 of file Value.hpp.

operator->() [1/2]

template<typename D >

D * dds::core::Value< D >::operator-> ( )

inherited

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.

Definition at line 111 of file Value.hpp.

operator->() [2/2]

template<typename D >

const D * dds::core::Value< D >::operator-> ( ) const

inherited

operator==()

template<typename D >

bool dds::core::Value< D >::operator== ( const Value< D > &  other ) const

inherited

Compare this Value with another Value

Parameters

other

Value

Returns

true if equal

Definition at line 93 of file Value.hpp.

total_count()

(

)

const

Returns

Total cumulative count the concerned DataWriter discovered a "match" with a DataReader. That is, it found a DataReader for the same Topic with a requested QoS that is compatible with that offered by the DataWriter.

total_count_change()

int32_t dds::core::status::PublicationMatchedStatus::total_count_change

(

)

const

Returns

The change in total_count since the last time the listener was called or the status was read.
