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.
ArgumentMappingTypeStrategy	Type strategy that returns the n-th input argument, mapping it with the provided function.
ArrayComparableElementTypeStrategy	An InputTypeStrategy that checks if the input argument is an ARRAY type and check whether its' elements are comparable.
ArrayOfStringArgumentTypeStrategy	Strategy for an argument that must be an array of strings.
CommonArgumentTypeStrategy	Argument type strategy that checks and casts for a common, least restrictive type of all arguments.
CommonArrayInputTypeStrategy	An InputTypeStrategy that expects that all arguments have a common array type.
CommonInputTypeStrategy	An InputTypeStrategy that expects that all arguments have a common type.
CommonTypeStrategy	Type strategy that returns a common, least restrictive type of all arguments.
ComparableTypeStrategy	An InputTypeStrategy that checks if all input arguments can be compared with each other with the minimal provided comparison.
CompositeArgumentTypeStrategy	Strategy that checks that the argument has a composite type.
ConstraintArgumentTypeStrategy	Strategy for an argument that must fulfill a given constraint.
ExplicitArgumentTypeStrategy	Strategy for an argument that corresponds to an explicitly defined type.
ExplicitTypeStrategy	Type strategy that returns a fixed DataType.
FamilyArgumentTypeStrategy	Strategy for an argument that corresponds to a given LogicalTypeFamily and nullability.
FirstTypeStrategy	Type strategy that returns the first type that could be inferred.
ForceNullableTypeStrategy	Forces a given type strategy to be nullable.
HiveAggDecimalPlusTypeStrategy	Type strategy that returns the result type of a decimal addition, used internally for implementing native SUM/AVG aggregations on a Decimal type.
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 compatible types.
MatchFamilyTypeStrategy	Type strategy that returns the given argument if it is of the same logical type family.
MissingTypeStrategy	Placeholder for a missing type strategy.
NullableIfArgsTypeStrategy	A type strategy that can be used to make a result type nullable if any or all of the selected input arguments are nullable.
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.
RepeatingSequenceInputTypeStrategy	InputTypeStrategy composed of an arbitrarily often repeating list of ArgumentTypeStrategys.
RootArgumentTypeStrategy	Strategy for an argument that corresponds to a given LogicalTypeRoot and nullability.
SequenceInputTypeStrategy	Strategy for inferring and validating a function signature like f(STRING, NUMERIC) or f(s STRING, n NUMERIC) using a sequence of ArgumentTypeStrategys.
SpecificInputTypeStrategies	Entry point for specific input type strategies not covered in InputTypeStrategies.
SpecificTypeStrategies	Entry point for specific type strategies not covered in TypeStrategies.
SubsequenceInputTypeStrategy	An InputTypeStrategy that lets you apply other strategies for subsequences of the actual arguments.
SubsequenceInputTypeStrategy.SubsequenceStrategyBuilder	A Builder for SubsequenceInputTypeStrategy.
SymbolArgumentTypeStrategy<T extends Enum<? extends TableSymbol>>	Strategy for a symbol argument of a specific TableSymbol enum.
ToTimestampLtzTypeStrategy	Type strategy of TO_TIMESTAMP_LTZ.
TypeLiteralArgumentTypeStrategy	Strategy that checks if an argument is a type literal.
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.
VaryingStringTypeStrategy	A type strategy that ensures that the result type is either LogicalTypeRoot.VARCHAR or LogicalTypeRoot.VARBINARY from their corresponding non-varying roots.
WildcardInputTypeStrategy	Strategy that does not perform any modification or validation of the input.
