public class ClassUtilities

extends java.lang.Object

Java's Class class can fail you on occasion when dealing with the primitive classes. Case in point: Class.forName(String) fails when passed "int" or any of the other 8 primitive names. However, this is the value that getName() returns when called on any of the primitive classes!!

This class provides primitive savvy methods for dealing with classes of all types

Field Summary

static java.lang.String	BOOLEAN_CLASS_NAME String representation of the primitive class boolean.
static java.lang.String	BYTE_CLASS_NAME String representation of the primitive class byte.
static java.lang.String	CHAR_CLASS_NAME String representation of the primitive class char.
static java.lang.String	DOUBLE_CLASS_NAME String representation of the primitive class double.
static java.lang.String	FLOAT_CLASS_NAME String representation of the primitive class float.
static java.lang.String	INT_CLASS_NAME String representation of the primitive class int.
static java.lang.String	LONG_CLASS_NAME String representation of the primitive class long.
static java.lang.String	SHORT_CLASS_NAME String representation of the primitive class short.
static java.lang.String	VOID_CLASS_NAME String representation of the primitive class void.

Method Summary

static java.lang.Class	forName(java.lang.String name) This method is intended to replace Class.forName(), with an alternate that fully supports all java class names.
static java.lang.String	getShortClassName(java.lang.Class type) generates a short class name for the given object.
static java.lang.String	getShortClassName(java.lang.Object object) Generates a short class name for the given object.
static java.lang.String	getShortClassName(java.lang.String className) Generates a short class name for the given classname.

Method Detail

getShortClassName

public static java.lang.String getShortClassName(java.lang.Object object)

Generates a short class name for the given object.

Parameters:

object - The Oobject you want to get the short class name for

Returns:

The short string reprentation of this object's class

See Also:

getShortClassName(Class)

getShortClassName

public static java.lang.String getShortClassName(java.lang.Class type)

generates a short class name for the given object.

 instanceof            ->  result string
 --------------------      --------------------
 ClassName             ->  "ClassName"
 com.foo.ClassName     ->  "ClassName"
 ClassName;            ->  "ClassName[]"
 ClassName$1           ->  "ClassName.1"
 ClassName$InnerClass  ->  "ClassName.InnerClass"
 

Parameters:

type - The Class that you want to get a short name for

Returns:

A short string representation of this class

getShortClassName

public static java.lang.String getShortClassName(java.lang.String className)

Generates a short class name for the given classname.

Parameters:

className - The fully qualified class name that you want shortened

Returns:

The short version of this fully qualified class name

See Also:

getShortClassName(Class)

forName

public static java.lang.Class forName(java.lang.String name)
                               throws java.lang.ClassNotFoundException

This method is intended to replace Class.forName(), with an alternate that fully supports all java class names. Class.forName() is incapable of processing the names of primitive types and the special type 'void'

Parameters:

name - The fully qualified name of the class you wish to instantiate

Returns:

An instance of that class

Throws:

java.lang.ClassNotFoundException - If the given class could not be found
