public IClassLoader(IClassLoader optionalParentIClassLoader)

Method Detail

postConstruct

protected final void postConstruct()

This method must be called by the constructor of the directly derived class. (The reason being is that this method invokes abstract loadIClass(String) which will not work until the implementing class is constructed.)

loadIClass

public final IClass loadIClass(java.lang.String fieldDescriptor)
                        throws java.lang.ClassNotFoundException

Get an IClass by field descriptor.

Parameters:

fieldDescriptor - E.g. 'Lpkg1/pkg2/Outer$Inner;'

Returns:

null if an IClass could not be loaded

Throws:

java.lang.ClassNotFoundException - An exception was raised while loading the IClass

findIClass

protected abstract IClass findIClass(java.lang.String descriptor)
                              throws java.lang.ClassNotFoundException

Find a new IClass by descriptor; return null if a class for that descriptor could not be found.

Similar ClassLoader.findClass(java.lang.String), this method must

• Get an IClass object from somewhere for the given type
• Call defineIClass(IClass) with that IClass object as the argument
• Return the IClass object

The format of a descriptor is defined in JVMS 4.3.2. Typical descriptors are:

• I (Integer)
• Lpkg1/pkg2/Cls; (Class declared in package)
• Lpkg1/pkg2/Outer$Inner; Member class

Notice that this method is never called for array types.

Notice that this method is never called from more than one thread at a time. In other words, implementations of this method need not be synchronized.

Returns:

null if a class with that descriptor could not be found

Throws:

java.lang.ClassNotFoundException - if an exception was raised while loading the class

defineIClass

protected final void defineIClass(IClass iClass)

Define an IClass in the context of this IClassLoader. If an IClass with that descriptor already exists, a RuntimeException is thrown.

This method should only be called from an implementation of findIClass(String).

Throws:

java.lang.RuntimeException - A different IClass object is already defined for this type

createJavacLikePathIClassLoader

public static IClassLoader createJavacLikePathIClassLoader(java.io.File[] optionalBootClassPath,
                                                           java.io.File[] optionalExtDirs,
                                                           java.io.File[] classPath)

Create an IClassLoader that looks for classes in the given "boot class path", then in the given "extension directories", and then in the given "class path".

The default for the optionalBootClassPath is the path defined in the system property "sun.boot.class.path", and the default for the optionalExtensionDirs is the path defined in the "java.ext.dirs" system property.
