Method Detail

getPrimitives

public static java.util.stream.Stream<java.lang.Class<?>> getPrimitives()

Get all primitive type classes

Returns:

A set containing all primitive types.

isPrimitive

public static boolean isPrimitive(java.lang.reflect.Type type)

Is the given type a primitive type as per the Java type system.

Parameters:

type - The type we wish to classify.

Returns:

True if the type is primitive, false otherwise.

isPrimitiveWrapper

public static boolean isPrimitiveWrapper(java.lang.reflect.Type type)

Is the type a wrapper for a primitive type as per the Java type system.

Parameters:

type - The type we wish to classify.

Returns:

True if the type is a primitive wrapper, false otherwise.

wrapPrimitive

public static <T extends java.lang.reflect.Type> T wrapPrimitive(T type)

If this TypeToken is a primitive type, determine the wrapped primitive type.

Type Parameters:

T - The type we wish to wrap.

Parameters:

type - The type we wish to wrap.

Returns:

The wrapper type of the primitive type this TypeToken represents, otherwise this TypeToken itself.

unwrapPrimitive

public static <T extends java.lang.reflect.Type> T unwrapPrimitive(T type)

If this TypeToken is a wrapper of a primitive type, determine the unwrapped primitive type.

Type Parameters:

T - The type we wish to unwrap.

Parameters:

type - The type we wish to unwrap.

Returns:

The primitive type wrapped by this TypeToken, otherwise this TypeToken itself.
