Interface Summary

Interface	Description
ArgumentCount	Defines the count of accepted arguments (including open intervals) that a function can take.
ArgumentTypeStrategy	Strategy for inferring and validating a single input argument type of a function call.
CallContext	Provides details about a function call during TypeInference.
InputTypeStrategy	Strategy for inferring and validating input arguments in a function call.
StateTypeStrategy	Strategy for inferring a function call's intermediate result data type (i.e. state entry).
TypeInferenceUtil.SurroundingInfo	Information what the outer world (i.e. an outer wrapping call) expects from the current function call.
TypeStrategy	Strategy for inferring a function call's result data type.
TypeTransformation	Transforms one data type to another.
