AndArgumentTypeStrategy Strategy for inferring and validating an argument using a conjunction of multiple ArgumentTypeStrategys into one like f(NUMERIC && LITERAL) Some ArgumentTypeStrategys cannot contribute an inferred type that is different from the input type (e.g.
AnyArgumentTypeStrategy Strategy for an argument that can be of any type.
ConstraintArgumentTypeStrategy Strategy for an argument that must fulfill a given constraint.
ExplicitArgumentTypeStrategy Strategy for an argument that corresponds to an explicitly defined type.
FamilyArgumentTypeStrategy Strategy for an argument that corresponds to a given LogicalTypeFamily and nullability.
LiteralArgumentTypeStrategy Strategy that checks if an argument is a literal.
OrArgumentTypeStrategy Strategy for inferring and validating an argument using a disjunction of multiple ArgumentTypeStrategys into one like f(NUMERIC || STRING).
OutputArgumentTypeStrategy Strategy for inferring an unknown argument type from the function's output DataType if available.
RootArgumentTypeStrategy Strategy for an argument that corresponds to a given LogicalTypeRoot and nullability.
SubsequenceInputTypeStrategy.SubsequenceStrategyBuilder A Builder for SubsequenceInputTypeStrategy.
WildcardInputTypeStrategy Strategy that does not perform any modification or validation of the input.
