1451 r"""Implement the 'endswith' operator.
1452
1453 Produces a LIKE expression that tests against a match for the end
1454 of a string value:
1455
1456 .. sourcecode:: sql
1457
1458 column LIKE '%' || <other>
1459
1460 E.g.::
1461
1462 stmt = select(sometable).where(sometable.c.column.endswith("foobar"))
1463
1464 Since the operator uses ``LIKE``, wildcard characters
1465 ``"%"`` and ``"_"`` that are present inside the <other> expression
1466 will behave like wildcards as well. For literal string
1467 values, the :paramref:`.ColumnOperators.endswith.autoescape` flag
1468 may be set to ``True`` to apply escaping to occurrences of these
1469 characters within the string value so that they match as themselves
1470 and not as wildcard characters. Alternatively, the
1471 :paramref:`.ColumnOperators.endswith.escape` parameter will establish
1472 a given character as an escape character which can be of use when
1473 the target expression is not a literal string.
1474
1475 :param other: expression to be compared. This is usually a plain
1476 string value, but can also be an arbitrary SQL expression. LIKE
1477 wildcard characters ``%`` and ``_`` are not escaped by default unless
1478 the :paramref:`.ColumnOperators.endswith.autoescape` flag is
1479 set to True.
1480
1481 :param autoescape: boolean; when True, establishes an escape character
1482 within the LIKE expression, then applies it to all occurrences of
1483 ``"%"``, ``"_"`` and the escape character itself within the
1484 comparison value, which is assumed to be a literal string and not a
1485 SQL expression.
1486
1487 An expression such as::
1488
1489 somecolumn.endswith("foo%bar", autoescape=True)
1490
1491 Will render as:
1492
1493 .. sourcecode:: sql
1494
1495 somecolumn LIKE '%' || :param ESCAPE '/'
1496
1497 With the value of ``:param`` as ``"foo/%bar"``.
1498
1499 :param escape: a character which when given will render with the
1500 ``ESCAPE`` keyword to establish that character as the escape
1501 character. This character can then be placed preceding occurrences
1502 of ``%`` and ``_`` to allow them to act as themselves and not
