      • findIClass

        @Nullable
public IClass findIClass​(java.lang.String fieldDescriptor)
                  throws java.lang.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

        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
        Parameters:
        fieldDescriptor - Field descriptor of the IClass to load, e.g. "Lpkg1/pkg2/Outer$Inner;"
        Returns:
        null if a class with that descriptor could not be found
        Throws:
        java.lang.ClassNotFoundException - An exception was raised while loading the IClass

        Finds the Java source file for the named class through the configured 'source resource finder' and parses it.
        Returns:
        null iff the source file could not be found
        Throws:
        java.io.IOException
