Method Detail

getDefaultValue
final public static Object getDefaultValue(Class cls)(Code)
	Returns the default value of a primitive class, or null if it is not a primitive class. Example, getDefaultValue(int.class) returns Integer(0).

getNotation
final public static char getNotation(String className)(Code)
	Returns the notation of a primitive class, or ((char)0) if it is not a primitive class. Example, I for int, Z for boolean...

isPrimitive
final public static boolean isPrimitive(String clsName)(Code)
	Tests whether a class name is a primitive class, e.g., int and void.

toClass
final public static Class toClass(String clsName)(Code)
	Converts a primitive from name to the class, or null if it is not a primitive class. Example, toClass("int") returns int.class.
