findIClassback to summary
public IClass findIClass(final String fieldDescriptor) throws ClassNotFoundException

Implements abstract org.codehaus.janino.IClassLoader.findIClass.

Doc from org.codehaus.janino.IClassLoader.findIClass.

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

Similar java.lang.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.

Parameters
fieldDescriptor:String

Field descriptor of the IClass to load, e.g. "Lpkg1/pkg2/Outer$Inner;"

Returns:IClass

null if a class with that descriptor could not be found

Annotations
@Override
@Nullable
