  • Constructor Details

    • ReflectedUniverse

      public ReflectedUniverse()
      Deprecated.
      Constructs a new reflected universe.

    • ReflectedUniverse

      Constructs a new reflected universe, with the given URLs representing additional search paths for imported classes (in addition to the CLASSPATH).

      Deprecated.
      Constructs a new reflected universe that uses the given class loader.
      Parameters:
      loader - the ClassLoader to use in this universe. If null, the default ClassLoader for the ReflectedUniverse class will be used.

  • Method Details

    • isInstance

      public static boolean isInstance​(java.lang.Class<?> c, java.lang.Object o)
      Deprecated.
      Returns whether the given object is compatible with the specified class for the purposes of reflection.
      Parameters:
      c - the base class
      o - the object that needs type checking
      Returns:
      true if the object is an instance of the base class

    • exec

      public java.lang.Object exec​(java.lang.String command) throws ReflectException
      Deprecated.
      Executes a command in the universe. The following syntaxes are valid:
      • import fully.qualified.package.ClassName
      • var = new ClassName(param1, ..., paramN)
      • var.method(param1, ..., paramN)
      • var2 = var.method(param1, ..., paramN)
      • ClassName.method(param1, ..., paramN)
      • var2 = ClassName.method(param1, ..., paramN)
      • var2 = var
      Important guidelines:
      • Any referenced class must be imported first using "import".
      • Variables can be exported from the universe with getVar().
      • Variables can be imported to the universe with setVar().
      • Each parameter must be either:
        1. a variable in the universe
        2. a static or instance field (i.e., no nested methods)
        3. a string literal (remember to escape the double quotes)
        4. an integer literal
        5. a long literal (ending in L)
        6. a double literal (containing a decimal point)
        7. a boolean literal (true or false)
        8. the null keyword
      Parameters:
      command - the command to be executed (see examples above)
      Returns:
      the result of executing the command. For import statements, the return value is null. Otherwise, the return value of the invoked method or the value assigned to a variable is returned (depending upon the command).
      Throws:
      ReflectException - if the command is invalid or fails to execute
