Field Detail

### value

    public final int value

Constructor Detail

### Expr.Constant

    public Expr.Constant(AbstractToken tok)

Method Detail

### evaluate

    public int evaluate(int currentByteAddress,
                        Context c)

  The `evaluate()` method computes the value of the expression in this context and returns its value. Since this is a constant, it simply returns its value.

  Specified by:
    `evaluate` in class `Expr`
  Parameters:
    `currentByteAddress` - the current byte address within the program
    `c` - the context in which to evaluate this expression
  Returns:
    the value of the expression as a 32-bit integer
