Constructor & Destructor Documentation

◆ HoneyPositionTable() [1/2]

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

inline

Create a new HoneyPositionTable 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.

Definition at line 147 of file honey_positionlist.h.

◆ delete_positionlist()

void HoneyPositionTable::delete_positionlist	(	Xapian::docid	did,
