java.lang.IllegalArgumentException - if the supplied class is null or does not represent a primitive type

isNonVoidPrimitive

public static boolean isNonVoidPrimitive(java.lang.Class clss)

Whether the class is strictly primitive - not including the Void.TYPE.

Parameters:

clss - the class

Returns:

true if and only if the class is primitive and not void

isNumberPrimitive

public static boolean isNumberPrimitive(java.lang.Class clss)

Whether the supplied class represents a number primitive.

Parameters:

clss - the class

Returns:

true if and only if clss equals the TYPE of some extension of Number

isBooleanPrimitive

public static boolean isBooleanPrimitive(java.lang.Class clss)

Whether the supplied class represents the boolean primitive.

Parameters:

clss - the class

Returns:

true if and only if clss == Boolean.TYPE
