The underlying enum type.

Enumerator:

HISTORY_SNAPSHOT	Indicates that the rti::sub::TopicQuery may only select samples that were in the DataWriter cache upon reception. [default]
CONTINUOUS	Indicates that the rti::sub::TopicQuery may continue selecting samples published after its reception. The subscribing application must explicitly delete the TopicQuery (see rti::sub::TopicQuery::close()) to signal the DataWriters to stop publishing samples for it.
