◆ AddPublisher()

bool AddPublisher ( const T &  _publisher)
inline

Add a new address associated to a given topic and node UUID.

Parameters
[in]_publisherNew publisher.
Returns
true if the new entry is added or false if not (because it was already stored).

◆ DelPublisherByNode()

bool DelPublisherByNode ( const std::string _topic,
const std::string _pUuid,
const std::string _nUuid 
)
inline

Remove a publisher associated to a given topic and UUID pair.

Parameters
[in]_topicTopic name
[in]_pUuidProcess UUID of the publisher.
[in]_nUuidNode UUID of the publisher.
Returns
True when the publisher was removed or false otherwise.

◆ DelPublishersByProc()

bool DelPublishersByProc ( const std::string _pUuid)
inline

Remove all the publishers associated to a given process.

Parameters
[in]_pUuidProcess' UUID of the publisher.
Returns
True when at least one address was removed or false otherwise.

◆ HasAnyPublishers()

bool HasAnyPublishers ( const std::string _topic,
const std::string _pUuid 
) const
inline

Return if there is any publisher stored for the given topic and process UUID.

Parameters
[in]_topicTopic name.
[in]_pUuidProcess UUID of the publisher.
Returns
True if there is at least one address stored for the topic and process UUID.

◆ HasPublisher()

bool HasPublisher ( const std::string _addr) const
inline

Return if the requested publisher's address is stored.

Parameters
[in]_addrPublisher's address requested
Returns
true if the publisher's address is stored.

◆ HasTopic() [1/2]

bool HasTopic ( const std::string _topic) const
inline

Return if there is any publisher stored for the given topic.

Parameters
[in]_topicTopic name.
Returns
True if there is at least one entry stored for the topic.

◆ HasTopic() [2/2]

bool HasTopic ( const std::string _topic,
const std::string _type 
) const
inline

Return if there is any publisher stored for the given topic and type.

Parameters
[in]_topicTopic name.
[in]_typeTopic type.
Returns
True if there is at least one entry stored for the topic and type.

◆ Print()

void Print ( ) const
inline

Print all the information for debugging purposes.

◆ Publisher()

bool Publisher ( const std::string _topic,
const std::string _pUuid,
const std::string _nUuid,
T &  _publisher 
) const
inline

Get the address information for a given topic and node UUID.

Parameters

[in]_pUuidProcess UUID of the publisher.
[in]_nUuidNode UUID of the publisher.
[out]_publisherPublisher's information requested.
Returns
true if a publisher is found for the given topic and UUID pair

◆ Publishers()

bool Publishers ( const std::string _topic,
std::map< std::string, std::vector< T >> &  _info 
) const
inline

Get the map of publishers stored for a given topic.

Parameters
[in]_topicTopic name.
[out]_infoMap of publishers requested.
Returns
true if at least there is one publisher stored.

◆ PublishersByNode()

const std::string _nUuid,
std::vector< T > &  _pubs 
) const
inline

Given a process UUID and the node UUID, the function returns the list of publishers contained in the node.

Parameters
[in]_pUuidProcess UUID.
