Calling Sequence

Parameters

Description

Close frees the resources associated with preparedstat. This happens automatically when preparedstat is garbage collected; however, you can call Close to release the resources immediately.

Any descendant modules of preparedstat are closed when preparedstat is closed. (A module is a descendant of a parent module if it is returned by one of the parent module's exports or if it is a descendant of one of the parent module's descendants.)
