static TopicList Create (const Container &_topics, const QualifiedTimeRange &_timeRange=QualifiedTimeRange::AllTime())
 Factory function that accepts any container type that can be passed through a range-for loop. This will insert the contents of _topics into a blank TopicList and then return it.
 
- Static Public Member Functions inherited from QueryOptions
static SqlStatement StandardMessageQueryClose ()
 Get a standard ending to a SQL statement that will instruct the queries to be ordered by the time the messages were received by the logger. It will also end the statement with a semicolon.
 
static SqlStatement StandardMessageQueryPreamble ()
 Get a standard SQL statement preamble, from the SELECT keyword up to (but not including) the WHERE keyword. This preamble will make sure that the statement is formatted in a way that MsgIter will have the information it needs.
