Class Summary

Class	Description
AndArgumentTypeStrategy	Strategy for inferring and validating an argument using a conjunction of multiple ArgumentTypeStrategys into one like f(NUMERIC && LITERAL)
AnyArgumentTypeStrategy	Strategy for an argument that can be of any type.
ExplicitArgumentTypeStrategy	Strategy for an argument that corresponds to an explicitly defined type.
ExplicitTypeStrategy	Type strategy that returns a fixed DataType.
LiteralArgumentTypeStrategy	Strategy that checks if an argument is a literal.
MappingTypeStrategy	Type strategy that maps an InputTypeStrategy to a TypeStrategy if the input strategy infers identical types.
MissingTypeStrategy	Placeholder for a missing type strategy.
OrArgumentTypeStrategy	Strategy for inferring and validating an argument using a disjunction of multiple ArgumentTypeStrategys into one like f(NUMERIC || STRING).
OrInputTypeStrategy	Strategy for inferring and validating the input using a disjunction of multiple InputTypeStrategys into one like f(NUMERIC) || f(STRING).
OutputArgumentTypeStrategy	Strategy for inferring an unknown argument type from the function's output DataType if available.
SequenceInputTypeStrategy	Strategy for inferring and validating a function signature like f(STRING, NUMERIC) or f(s STRING, n NUMERIC) using a sequence of ArgumentTypeStrategys.
UseArgumentTypeStrategy	Type strategy that returns the n-th input argument.
VaryingSequenceInputTypeStrategy	Strategy for inferring and validating a varying function signature like f(INT, STRING, NUMERIC...) or f(i INT, str STRING, num NUMERIC...) using a sequence of ArgumentTypeStrategys.
WildcardInputTypeStrategy	Strategy that does not perform any modification or validation of the input.
