findIClass

@Nullable
protected IClass findIClass(String descriptor)
                     throws ClassNotFoundException

Description copied from class: IClassLoader

Finds a new IClass by descriptor and calls IClassLoader.defineIClass(IClass).

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

• Get an IClass object from somewhere for the given type
• Call IClassLoader.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/Clazz; (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 thread-safe.

Specified by:

findIClass in class IClassLoader

Returns:

null if a class with that descriptor could not be found

Throws:

ClassNotFoundException - An exception was raised while loading the class
