class comparator_factory(sqltypes.Concatenable.Comparator):

View In Hierarchy

Define comparison operations for range types.
Method __ne__ Boolean expression. Returns true if two ranges are not equal
Method adjacent​_to Boolean expression. Returns true if the range in the column is adjacent to the range in the operand.
Method contained​_by Boolean expression. Returns true if the column is contained within the right hand operand.
Method contains Boolean expression. Returns true if the right hand operand, which can be an element or a range, is contained within the column.
Method not​_extend​_left​_of Boolean expression. Returns true if the range in the column does not extend left of the range in the operand.
Method not​_extend​_right​_of Boolean expression. Returns true if the range in the column does not extend right of the range in the operand.
Method overlaps Boolean expression. Returns true if the column overlaps (has points in common with) the right hand operand.
Method strictly​_left​_of Boolean expression. Returns true if the column is strictly left of the right hand operand.
Method strictly​_right​_of Boolean expression. Returns true if the column is strictly right of the right hand operand.
Method __add__ Range expression. Returns the union of the two ranges. Will raise an exception if the resulting range is not contiguous.

Inherited from Comparator:

Method ​_adapt​_expression evaluate the return type of <self> <op> <othertype>, and apply any adaptations to the given operator.

def __ne__(self, other):
overrides sqlalchemy.sql.operators.ColumnOperators.__ne__
Boolean expression. Returns true if two ranges are not equal
def adjacent_to(self, other):
Boolean expression. Returns true if the range in the column is adjacent to the range in the operand.
def contained_by(self, other):
Boolean expression. Returns true if the column is contained within the right hand operand.
def contains(self, other, **kw):
overrides sqlalchemy.sql.operators.ColumnOperators.contains

Boolean expression. Returns true if the right hand operand, which can be an element or a range, is contained within the column.

kwargs may be ignored by this operator but are required for API conformance.

def not_extend_left_of(self, other):
Boolean expression. Returns true if the range in the column does not extend left of the range in the operand.
def not_extend_right_of(self, other):
Boolean expression. Returns true if the range in the column does not extend right of the range in the operand.
def overlaps(self, other):
Boolean expression. Returns true if the column overlaps (has points in common with) the right hand operand.
def strictly_left_of(self, other):
Boolean expression. Returns true if the column is strictly left of the right hand operand.
def strictly_right_of(self, other):
Boolean expression. Returns true if the column is strictly right of the right hand operand.
def __add__(self, other):
overrides sqlalchemy.sql.operators.ColumnOperators.__add__
Range expression. Returns the union of the two ranges. Will raise an exception if the resulting range is not contiguous.
