实现ArgumentTypeStrategy的org.apache.flink.table.types.inference.strategies中的类

限定符和类型	类和说明
class	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.
class	AnyArgumentTypeStrategy Strategy for an argument that can be of any type.
class	CompositeArgumentTypeStrategy Strategy that checks that the argument has a composite type.
class	ConstraintArgumentTypeStrategy Strategy for an argument that must fulfill a given constraint.
class	ExplicitArgumentTypeStrategy Strategy for an argument that corresponds to an explicitly defined type.
class	FamilyArgumentTypeStrategy Strategy for an argument that corresponds to a given LogicalTypeFamily and nullability.
class	LiteralArgumentTypeStrategy Strategy that checks if an argument is a literal.
class	OrArgumentTypeStrategy Strategy for inferring and validating an argument using a disjunction of multiple ArgumentTypeStrategys into one like f(NUMERIC || STRING).
class	OutputArgumentTypeStrategy Strategy for inferring an unknown argument type from the function's output DataType if available.
class	RootArgumentTypeStrategy Strategy for an argument that corresponds to a given LogicalTypeRoot and nullability.
