Class DefaultClassLoaderStrategy

java.lang.Object

jodd.util.cl.DefaultClassLoaderStrategy

All Implemented Interfaces:

ClassLoaderStrategy

public class DefaultClassLoaderStrategy
extends java.lang.Object
implements ClassLoaderStrategy

Default Jodd class loader strategy. Loads a class with a given name dynamically, more reliable then Class.forName.

Class will be loaded using class loaders in the following order:

• provided class loader (if any)
• Thread.currentThread().getContextClassLoader()}
• caller classloader

Field Detail

PRIMITIVE_TYPE_NAMES

public static final java.lang.String[] PRIMITIVE_TYPE_NAMES

List of primitive type names.

PRIMITIVE_TYPES

public static final java.lang.Class[] PRIMITIVE_TYPES

List of primitive types that matches names list.

PRIMITIVE_BYTECODE_NAME

public static final char[] PRIMITIVE_BYTECODE_NAME

List of primitive bytecode characters that matches names list.

loadArrayClassByComponentTypes

protected boolean loadArrayClassByComponentTypes

Constructor Detail

DefaultClassLoaderStrategy

public DefaultClassLoaderStrategy()

Method Detail

isLoadArrayClassByComponentTypes

public boolean isLoadArrayClassByComponentTypes()

Returns arrays class loading strategy.

setLoadArrayClassByComponentTypes

public void setLoadArrayClassByComponentTypes(boolean loadArrayClassByComponentTypes)

Defines arrays class loading strategy. If false (default), classes will be loaded by Class.forName. If true, classes will be loaded by reflection and component types.

prepareArrayClassnameForLoading

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

Prepares classname for loading, respecting the arrays. Returns null if class name is not an array.

loadClass

public java.lang.Class loadClass(java.lang.String className,
                                 java.lang.ClassLoader classLoader)
                          throws java.lang.ClassNotFoundException

Loads class by name.

Specified by:

loadClass in interface ClassLoaderStrategy

Throws:

java.lang.ClassNotFoundException

loadClass

protected java.lang.Class loadClass(java.lang.String className,
                                    java.lang.String arrayClassName,
                                    java.lang.ClassLoader classLoader)

Loads a class using provided class loader. If class is an array, it will be first loaded using the Class.forName! We must use this since for JDK >= 6 arrays will be not loaded using classloader, but only with forName method. However, array loading strategy can be changed.

loadArrayClassByComponentType

protected java.lang.Class loadArrayClassByComponentType(java.lang.String className,
                                                        java.lang.ClassLoader classLoader)
                                                 throws java.lang.ClassNotFoundException

Loads array class using component type.

Throws:

java.lang.ClassNotFoundException
