### print

    public void print(Object obj)

  Description copied from class: `GrailsPrintWriter`
  Print an object. The string produced by the ``String.valueOf(Object)`` method is translated into bytes according to the platform's default character encoding, and these bytes are written in exactly the manner of the ``GrailsPrintWriter.write(int)`` method.

  Overrides:
    `print` in class `GrailsPrintWriter`
  Parameters:
    `obj` - The `Object` to be printed
  See Also:
    `Object.toString()`

### print

    public void print(String s)

  Description copied from class: `GrailsPrintWriter`
  Print a string. If the argument is `null` then the string `""` is printed. Otherwise, the string's characters are converted into bytes according to the platform's default character encoding, and these bytes are written in exactly the manner of the ``GrailsPrintWriter.write(int)`` method.

  Overrides:
    `print` in class `GrailsPrintWriter`
  Parameters:
    `s` - The `String` to be printed

### print

  Overrides:
    `print` in class `GrailsPrintWriter`

### write

    public void write(String s)

  Description copied from class: `GrailsPrintWriter`
  Writes a string. If the argument is `null` then the string `""` is printed.
