Member Function Documentation

add() [1/2]

int add ( const char *  topic, const CorrelationId &  correlationId = CorrelationId()  )

virtual

Add the specified topic to this list, optionally specifying a correlationId. Returns 0 on success or negative number on failure. After a successful call to add() the status for this entry is NOT_CREATED.

add() [2/2]

int add ( Message const &  message, const CorrelationId &  correlationId = CorrelationId()  )

virtual

Add the topic contained in the specified topicSubscribedMessage or resolutionSuccessMessage to this list, optionally specifying a correlationId. Returns 0 on success or a negative number on failure. After a successful call to add() the status for this entry is NOT_CREATED.

correlationIdAt()

CorrelationId correlationIdAt ( size_t  index ) const

virtual

Returns the CorrelationId of the specified indexth entry in this TopicList. If index >= size() an exception is thrown.

impl() [1/2]

const blpapi_TopicList_t * impl

(

)

message()

Message const message ( const CorrelationId &  correlationId ) const

virtual

Returns the value of the message received during creation of the topic identified by the specified correlationId. If correlationId does not identify an entry in this TopicList, an exception is thrown.

The message returned can be used when creating an instance of Topic.

messageAt()

Message const messageAt ( size_t  index ) const

virtual

Returns the value of the message received during creation of the specified indexth entry in this TopicList. If index >= size(), an exception is thrown.

The message returned can be used when creating an instance of Topic.

size()

size_t size ( ) const

virtual

Returns the number of entries in this list.

status()

int status ( const CorrelationId &  correlationId ) const

virtual

Returns the status of the entry in this TopicList identified by the specified correlationId. This may be NOT_CREATED, CREATED and FAILURE. If the correlationId does not identify an entry in this TopicList then an exception is thrown.

statusAt()

int statusAt ( size_t  index ) const

virtual

Returns the status of the specified indexth entry in this TopicList. This may be NOT_CREATED, CREATED and FAILURE. If index >= size() an exception is thrown.

topicString()

const char * topicString ( const CorrelationId &  correlationId ) const

virtual

Returns a pointer to the topic of the entry identified by the specified correlationId. If the correlationId does not identify an entry in this TopicList then an exception is thrown.

topicStringAt()

const char * topicStringAt ( size_t  index ) const

virtual

Returns a pointer to the topic of the specified indexth entry. If index >= size() an exception is thrown.
