Virtual Table Cursor Object
struct sqlite3_vtab_cursor;
Every virtual table module implementation uses a subclass of the following
structure to describe cursors that point into the virtual table and are used
to loop through the virtual table. Cursors are created using the xOpen method
of the module and are destroyed by the xClose method. Cursors are used by the
xFilter, xNext, xEof, xColumn, and xRowid methods of the module. Each module
implementation will define the content of a cursor structure to suit its own
needs.
This superclass exists in order to define fields of the cursor
that are common to all implementations.
