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::DatabaseCorruptErroris thrown if a problem is found with the database's format.
Xapian::DatabaseOpeningErrorthrown if database can't be opened.
Xapian::DatabaseVersionErrorthrown if database is in an unsupported format. This implies that the database was created by an older or newer version of Xapian.
Parameters
dbdirdirectory holding glass tables
block_sizeBlock 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.

Returns
A constant indicating the backend type.

Parameters
new_revisionThe 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.
