Constructor & Destructor Documentation

HoneyPostListTable() [1/2]

HoneyPostListTable::HoneyPostListTable ( const std::string &  dbdir, bool  readonly  )

inline

Create a new HoneyPostListTable object.

This method does not create or open the table on disk - you must call the create() or open() methods respectively!

Parameters

dbdir	The directory the honey database is stored in.
readonly	true if we're opening read-only, else false.
