    • postConstruct

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

    • requireType

      private IClass requireType(String descriptor)

    • getMethod

      @Nullable private static IClass.IMethod getMethod(IClass declaringType, String name, IClass... parameterTypes)
      Returns:
      null iff the declaringType does not declare a method with that name and parameter types

    • requireMethod

      private static IClass.IMethod requireMethod(IClass declaringType, String name, IClass... parameterTypes)
      Throws:
      AssertionError - The declaringType does not declare a method with that name and parameter types

    • requireConstructor

      private static IClass.IConstructor requireConstructor(IClass declaringType, IClass... parameterTypes)

    • loadIClass

      @Nullable public final IClass loadIClass(String fieldDescriptor) throws ClassNotFoundException
      Gets an IClass by field descriptor.
      Parameters:
      fieldDescriptor - E.g. 'Lpkg1/pkg2/Outer$Inner;'
      Returns:
      null if an IClass could not be loaded
      Throws:
      ClassNotFoundException - An exception was raised while loading the IClass

    • findIClass

      @Nullable protected abstract IClass findIClass(String descriptor) throws ClassNotFoundException
      Finds a new IClass by descriptor and calls 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.

      Returns:
      null if a class with that descriptor could not be found
      Throws:
      ClassNotFoundException - An exception was raised while loading the class

    • defineIClass

      protected final void defineIClass(IClass iClass)
      Defines an IClass in the context of this IClassLoader.

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

      Throws:
      InternalCompilerException - A different IClass object is already defined for this type

    • getArrayIClass

      public IClass getArrayIClass(IClass componentType, int n)
      Gets an IClass that represents an n-dimensional array of this type.
      Parameters:
      componentType - Required because the superclass of an array class is Object by definition
      n - Dimension count

    • getArrayIClass

      public IClass getArrayIClass(IClass componentType)
      Gets an IClass that represents an array of this type.
      Parameters:
      componentType - Required because the superclass of an array class is Object by definition

    • getArrayIClass2

      private IClass getArrayIClass2(IClass componentType)
      Parameters:
      objectType - Must pass TYPE_java_lang_Object here

    • createJavacLikePathIClassLoader

      public static IClassLoader createJavacLikePathIClassLoader(@Nullable File[] bootClassPath, @Nullable File[] extDirs, File[] classPath)
      Creates 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 bootClassPath is the path defined in the system property "sun.boot.class.path", and the default for the extensionDirs is the path defined in the "java.ext.dirs" system property.
