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.

Member Function Documentation

◆ apply()

void GlassDatabase::apply ( )

private

Apply any outstanding changes to the tables.

If an error occurs during this operation, this will be signalled by an exception being thrown. In this case the contents of the tables on disk will be left in an unmodified state (though possibly with increased revision numbers), and the outstanding changes will be lost.
