Inherited from RangeOperators:

Class

comparator​_factory

Define comparison operations for range types.

Inherited from TypeEngine:

Class	​Comparator	Base class for custom comparison operations defined at the type level. See .TypeEngine.comparator_factory.
Method	adapt	Produce an "adapted" form of this type, given an "impl" class to work with.
Method	as​_generic	Return an instance of the generic type corresponding to this type using heuristic rule. The method may be overridden if this heuristic rule is not sufficient.
Method	bind​_expression	Given a bind value (i.e. a .BindParameter instance), return a SQL expression in its place.
Method	bind​_processor	Return a conversion function for processing bind values.
Method	coerce​_compared​_value	Suggest a type for a 'coerced' Python value in an expression.
Method	column​_expression	Given a SELECT column expression, return a wrapping SQL expression.
Method	compare​_against​_backend	Compare this type against the given backend type.
Method	compare​_values	Compare two values for equality.
Method	compile	Produce a string-compiled form of this .TypeEngine.
Method	dialect​_impl	Return a dialect-specific implementation for this .TypeEngine.
Method	evaluates​_none	Return a copy of this type which has the .should_evaluate_none flag set to True.
Method	get​_dbapi​_type	Return the corresponding type object from the underlying DB-API, if any.
Method	literal​_processor	Return a conversion function for processing literal values that are to be rendered directly without using binds.
Method	result​_processor	Return a conversion function for processing result row values.
Method	with​_variant	Produce a new type object that will utilize the given type when applied to the dialect of the given name.
Class Variable	hashable	Flag, if False, means values from this type aren't hashable.
Class Variable	should​_evaluate​_none	If True, the Python constant None is considered to be handled explicitly by this type.
Class Variable	sort​_key​_function	A sorting function that can be passed as the key to sorted.
Static Method	​_to​_instance	Undocumented
Method	__repr__	Undocumented
Method	__str__	Undocumented
Method	​_cached​_bind​_processor	Return a dialect-specific bind processor for this type.
Method	​_cached​_custom​_processor	Undocumented
Method	​_cached​_literal​_processor	Return a dialect-specific literal processor for this type.
Method	​_cached​_result​_processor	Return a dialect-specific result processor for this type.
Method	​_compare​_type​_affinity	Undocumented
Method	​_default​_dialect	Undocumented
Method	​_dialect​_info	Return a dialect-specific registry which caches a dialect-specific implementation, bind processing function, and one or more result processing functions.
Method	​_gen​_dialect​_impl	Undocumented
Method	​_resolve​_for​_literal	adjust this type given a literal Python value that will be stored in a bound parameter.
Method	​_unwrapped​_dialect​_impl	Return the 'unwrapped' dialect impl for this type.

Class Variable	​_is​_tuple​_type	Undocumented
Class Variable	​_is​_type​_decorator	Undocumented
Class Variable	​_isnull	Undocumented
Class Variable	​_sqla​_type	Undocumented
Property	​_generic​_type​_affinity	Undocumented
Property	​_has​_bind​_expression	memoized boolean, check if bind_expression is implemented.
Property	​_has​_column​_expression	memoized boolean, check if column_expression is implemented.
Property	​_static​_cache​_key	Undocumented
Property	​_type​_affinity	Return a rudimental 'affinity' value expressing the general class of type.
Property	python​_type	Return the Python type object expected to be returned by instances of this type, if known.

Inherited from Traversible (via TypeEngine):

Method	get​_children	Return immediate child .visitors.Traversible elements of this .visitors.Traversible.
