## Depreciar uma *operação de rota*

Se você precisar marcar uma *operação de rota* como <abbr title="obsoleta, recomendada não usá-la">descontinuada</abbr>, mas sem removê-la, passe o parâmetro `deprecated`:

```Python hl_lines="16"

#
# The variable '$$AccessContext$$' means allcommon.AccessContext.
#
# Example:
# map:{
#     ; commonColumnMap = map:{
#         ; REGISTER_DATETIME=TIMESTAMP ; REGISTER_USER=VARCHAR
#         ; UPDATE_DATETIME=TIMESTAMP   ; UPDATE_USER=VARCHAR
#     }
#     ; beforeInsertMap = map:{
#         ; REGISTER_DATETIME = $$AccessContext$$.getAccessLocalDateTimeOnThread()
#         ; REGISTER_USER     = $$AccessContext$$.getAccessUserOnThread()
