Class IndentedOutputStream

└ OutputStream

└ Object

An output stream which indents the lines it writes. IndentedOutputStream sits "on top of" another stream, directing its output to the underlying stream. Closing the IndentedOutputStream does not directly close the underlying stream, but if the IndentedOutputStream holds the only remaining reference to the underlying stream, then discarding the IndentedOutputStream will cause the underlying stream to likewise be discarded and thus closed.

It is possible to continue writing directly to the underlying stream despite having created an IndentedOutputStream on top of it; naturally, such writes will not be processed by the IndentedOutputStream and thus may interact badly with it.

Initializers


init
(out:OutputStream)

Creates a new IndentedOutputStream.

Parameters:: out - the underlying output stream

Fields

var level:Int

The current indentation level, in units of indentSize. Each line written to the underlying stream will be prefixed by indentSize * level spaces.

var indentSize:Int

The number of spaces represented by each increment of level. Defaults to 4.

Instance Methods

@override

method write

(b:UInt8
):Error?

Writes a single byte.

Parameters:: b - value of type UInt8

Overrides:: frost.io.OutputStream.write

@override

method write

(ptr:Pointer<UInt8>,
 count:Int
):Error?

Writes a block of data to this stream.

Parameters:: ptr - Pointer to the data to write
count - number of bytes to write

Overrides:: frost.io.OutputStream.write
