Constructor & Destructor Documentation

HoneyTermListTable() [1/2]

HoneyTermListTable::HoneyTermListTable ( const std::string &  dbdir, bool  readonly, bool  lazy_  )

inline

Create a new HoneyTermListTable 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.
lazy_	Don't create a termlist if there isn't one.
