| 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 |
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. |
