class Generator[source]#

Bases: object

A generator is function that generates a set of values from a set of given values. Semantically, it certifies that the generated values satisfy a given condition.

Methods

short_str()

Attributes

`argument_names`	The names of the arguments of the operator.
`argument_types`	The types of the arguments of the operator.
`input_vars`	The input variables of the function.
`name`	The name of the generator.
`arguments`	The arguments of the generator.
`certifies`	The condition that the generated values should satisfy.
`context`	The context values that the generator depends on.
`generates`	The values that the generator generates.
`function`	The declaration of the underlying function that generates the values.
`output_vars`	The output variables of the function.
`output_types`	The output type of the function.
`flatten_certifies`	The condition that the generated values should satisfy, flattened.
`implementation`	The implementation of the generator.
`priority`	The priority of the generator.
`unsolvable`	Whether the generator is unsolvable.
