Static Method	​_convert​_value​_noop	Undocumented
Method	__getstate__	Undocumented
Method	​_parse​_expressions	Undocumented
Method	​_resolve​_output​_field	Attempt to infer the output type of the expression. If the output fields of all source fields match then, simply infer the same type here. This isn't always correct, but it makes sense most of the time.
Method	asc	Undocumented
Method	desc	Undocumented
Method	flatten	Recursively yield this expression and all subexpressions, in depth-first order.
Method	get​_db​_converters	Undocumented
Method	get​_group​_by​_cols	Undocumented
Method	get​_lookup	Undocumented
Method	get​_source​_fields	Return the underlying field types used by this aggregate.
Method	get​_transform	Undocumented
Method	relabeled​_clone	Undocumented
Method	reverse​_ordering	Undocumented

Class Variable	is​_summary	Undocumented
Class Variable	window​_compatible	Undocumented
Property	​_output​_field​_or​_none	Return the output field of this expression, or None if _resolve_output_field() didn't return an output type.
Property	conditional	Undocumented
Property	contains​_aggregate	Undocumented
Property	contains​_column​_references	Undocumented
Property	contains​_over​_clause	Undocumented
