static Class<?>	forName(String name) Deprecated. Same as Class.forName(), except that it works for primitive types.
static Class<?>	forName(String name, ClassLoader classLoader) Deprecated. Replacement for Class.forName() that also returns Class instances for primitives (like "int") and array class names (like "String[]").

static ClassLoader	getCallerClassLoader(Class<?> caller) Deprecated.
static ClassLoader	getClassLoader() Deprecated. Return the default ClassLoader to use: typically the thread context ClassLoader, if available; the ClassLoader that loaded the ClassUtils class will be used as fallback.

Method Detail

forNameWithThreadContextClassLoader

public static Class<?> forNameWithThreadContextClassLoader(String name)
                                                    throws ClassNotFoundException

Deprecated.

Throws:

ClassNotFoundException

forNameWithCallerClassLoader

public static Class<?> forNameWithCallerClassLoader(String name,
                                                    Class<?> caller)
                                             throws ClassNotFoundException

Deprecated.

Throws:

ClassNotFoundException

getCallerClassLoader

public static ClassLoader getCallerClassLoader(Class<?> caller)

Deprecated.

getClassLoader

public static ClassLoader getClassLoader(Class<?> clazz)

Deprecated.

get class loader

Parameters:

clazz -

Returns:

class loader

getClassLoader

public static ClassLoader getClassLoader()

Deprecated.

Return the default ClassLoader to use: typically the thread context ClassLoader, if available; the ClassLoader that loaded the ClassUtils class will be used as fallback.

Call this method if you intend to use the thread context ClassLoader in a scenario where you absolutely need a non-null ClassLoader reference: for example, for class path resource loading (but not necessarily for Class.forName, which accepts a null ClassLoader reference as well).

Returns:

the default ClassLoader (never null)

Thread.getContextClassLoader()

forName

public static Class<?> forName(String name)
                        throws ClassNotFoundException

Deprecated.

Same as Class.forName(), except that it works for primitive types.

Throws:

ClassNotFoundException

forName

public static Class<?> forName(String name,
                               ClassLoader classLoader)
                        throws ClassNotFoundException,
                               LinkageError

Deprecated.

Replacement for Class.forName() that also returns Class instances for primitives (like "int") and array class names (like "String[]").

Parameters:

name - the name of the Class

classLoader - the class loader to use (may be null, which indicates the default class loader)

Returns:

Class instance for the supplied name

Throws:

ClassNotFoundException - if the class was not found

LinkageError - if the class file could not be loaded

See Also:

Class.forName(String, boolean, ClassLoader)

resolvePrimitiveClassName

public static Class<?> resolvePrimitiveClassName(String name)

Deprecated.

Resolve the given class name as primitive class, if appropriate, according to the JVM's naming rules for primitive classes.

Also supports the JVM's internal class names for primitive arrays. Does not support the "[]" suffix notation for primitive arrays; this is only supported by forName(java.lang.String).

Parameters:

name - the name of the potentially primitive class

Returns:

the primitive class, or null if the name does not denote a primitive class or primitive array class

toShortString

public static String toShortString(Object obj)

Deprecated.

simpleClassName

public static String simpleClassName(Class<?> clazz)

Deprecated.

isSetter

public static boolean isSetter(Method method)

Deprecated. Replace to MethodUtils#isSetter(Method)

See Also:

MethodUtils.isSetter(Method)

isGetter

public static boolean isGetter(Method method)

Deprecated. Replace to MethodUtils#isGetter(Method)

isTypeMatch

public static boolean isTypeMatch(Class<?> type,
                                  String value)

We only check boolean value at this moment.

Parameters:

type -

value -

Returns:
