Overview
| Comment: | Major cleanup and refactoring of the ISQLiteManagedModule interface. Fix a small memory leak in DeclareVirtualTable. Add the ability to persist SQLiteValue values beyond the duration of the method call in progress. Add SQLiteVirtualTable base class. Update SQLiteVirtualTableCursor base class to be IDisposable and to support storing the filtering parameters. Make parameter naming in the ISQLiteManagedModule interface consistent with other managed code. Add SQLiteVirtualTable parameter to the ISQLiteManagedModule interface methods where necessary. Remove incorrect SQLiteIndex object creation from the IndexToIntPtr method. Keep track of all managed table and cursor object instances associated with their native pointers. Zero out the native sqlite3_vtab object right after allocation. Correct declarations for the sqlite3_vtab and sqlite3_vtab_cursor structures. Add SQLiteModuleEnumerable and SQLiteVirtualTableCursorEnumerable classes to allow an IEnumerable to provide the data for a virtual table. |
