      name - the name of the enum constant to be returned.
      Returns:
      the enum constant with the specified name
      Throws:
      java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
      java.lang.NullPointerException - if the argument is null

    • loadFromResource

      public static java.lang.Class loadFromResource​(@NotNull java.lang.String className, @NotNull java.lang.String resourceName) throws java.io.IOException, java.lang.ClassNotFoundException

      className - expected class name of the outer class.
      resourceName - as the full file name with extension.
      Returns:
      the outer class loaded.
      Throws:
      java.io.IOException - the resource could not be loaded.
      java.lang.ClassNotFoundException - the class name didn't match or failed to initialise.

    • addClassPath

      public static boolean addClassPath​(@NotNull java.lang.String dir)
      Add a directory to the class path for compiling. This can be required with custom
      Parameters:
      dir - to add.
      Returns:
      whether the directory was found, if not it is not added either.
