public final class NumberTypes
extends Object

Contains NumberType utilities.

Method Summary

Modifier and Type	Method and Description
static <T> @Nullable NumberType<T>	from(@Nullable Class<T> clazz) Returns, if applicable, the NumberType instance from StandardNumberType and MoreNumberTypes that corresponds to the provided class, null otherwise.
static Stream<NumberType<?>>	streamThroughAll() Provides a stream of all NumberType implementations provided by this library.
static Number	unwrapToStandardNumberType(Number number) Unwraps the number to a basic number type, if applicable.
static @Nullable Number	unwrapToStandardNumberType(@Nullable Object object) Unwraps the object to a basic number type and returns the value if the given object is a Number or Character.

Method Detail

from

@Nullable
public static <T> @Nullable NumberType<T> from(@Nullable
                                                         @Nullable Class<T> clazz)

Returns, if applicable, the NumberType instance from StandardNumberType and MoreNumberTypes that corresponds to the provided class, null otherwise. Both primitive and equivalent reference type are supported (e.g. int.class and Integer.class return the same instance).

If you do not need the returned NumberType to produce values that exactly match the given class (i.e. if you need the number type for range information and reading of values), you can use unwrapToStandardNumberType(Number) to match more types.

Type Parameters:

T - the class's type

Parameters:

clazz - the class to process

Returns:

the number type for the given class, null if not available

streamThroughAll

public static Stream<NumberType<?>> streamThroughAll()

Provides a stream of all NumberType implementations provided by this library.

Returns:

stream of all number types by this library

unwrapToStandardNumberType

@Nullable
public static @Nullable Number unwrapToStandardNumberType(@Nullable
                                                                    @Nullable Object object)

Unwraps the object to a basic number type and returns the value if the given object is a Number or Character.

Specifically, this method converts Character to an int, and it unwraps the number types AtomicInteger, AtomicLong, LongAccumulator, LongAdder, DoubleAccumulator and DoubleAdder to their respective underlying type.

Parameters:

object - the object to unwrap

Returns:

the number value the object could be unwrapped to

unwrapToStandardNumberType

public static Number unwrapToStandardNumberType(Number number)

Unwraps the number to a basic number type, if applicable.

Specifically, this method unwraps the number types AtomicInteger, AtomicLong, LongAccumulator, LongAdder, DoubleAccumulator and DoubleAdder to their respective underlying type.

Parameters:

number - the object to unwrap

Returns:

the number value the object could be unwrapped to
