Constructor & Destructor Documentation

◆ GlassDatabase() [1/2]

GlassDatabase::GlassDatabase	(	const string &	db_dir_,
		int	flags = `Xapian::DB_READONLY_`,
		unsigned int	block_size = `0u`
	)

explicit

Create and open a glass database.

Exceptions

Xapian::DatabaseCorruptError	is thrown if a problem is found with the database's format.
Xapian::DatabaseOpeningError	thrown if database can't be opened.
Xapian::DatabaseVersionError	thrown if database is in an unsupported format. This implies that the database was created by an older or newer version of Xapian.

Parameters

dbdir	directory holding glass tables
block_size	Block size, in bytes, to use when creating tables. This is only important, and has the correct value, when the database is being created.

Request and later collect a document from the database.

Multiple documents can be requested with request_document(), and then collected with collect_document(). Allows the backend to optimise (e.g. the remote backend can start requests for all the documents so they fetch in parallel).

If a backend doesn't support this, request_document() can be a no-op and collect_document() the same as open_document().

This updates the disk tables so that the currently open revision becomes the specified revision number.

Parameters

new_revision The new revision number to store. This must be greater than the current revision number. FIXME: If we support rewinding to a previous revision, maybe this needs to be greater than any previously used revision.
