  • Method Details

    • getType

      public Type getType()
      Description copied from class: Expression
      Get the type returned by this expression
      Specified by:
      getType in class Expression
      Returns:
      The type of this expression

    • reset

      public void reset()
      Description copied from class: Expression
      Resets any labels in expressions so that the method can be regenerated
      Overrides:
      reset in class Expression

    • findCaptured

      public void findCaptured(Environment env)
      Description copied from class: Expression

      Specified by:
      convertToFullTailCalls in class Expression
      Parameters:
      inTailPosition - True if this expression is called from the tail position
      Returns:
      A version of this expression whose types are compatible with full tail call optimization

    • generate

      public void generate(ClassGenerator generator, Environment env, boolean inTailPosition)
      Description copied from class: Expression
      Generate the bytecode for this expression
      Specified by:
      generate in class Expression
      Parameters:
      generator - The generator for generating instructions and additional declarations
      env - The environment containing the local variables currently visible to this expression
