Method	compile	Produce a string-compiled form of this :class:`.TypeEngine`.
Method	copy	Undocumented
Method	copy_value	Undocumented
Method	evaluates_none	Return a copy of this type which has the :attr:`.should_evaluate_none` flag set to True.
Method	get_dbapi_type	Return the corresponding type object from the underlying DB-API, if any.
Method	with_variant	Produce a copy of this type object that will utilize the given type when applied to the dialect of the given name.
Class Variable	render_literal_cast	render casts when rendering a value as an inline literal, e.g. with :meth:`.TypeEngine.literal_processor`.
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.

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	_resolve_for_python_type	given a Python type (e.g. ``int``, ``str``, etc. ) return an instance of this :class:`.TypeEngine` that's appropriate for this type.
