21 Simple way to hook up a line-tokenizer to an arbitrary InputStream,
|
|
|
22 such as a file conduit:
|
|
|
23 ---
|
|
|
24 auto input = new LineInput (new FileInput("path"));
|
|
|
25 foreach (line; input)
|
|
|
26 ...
|
|
|
27 input.close;
|
|
|
28 ---
|
|
|

|
|
|
30 Note that this is just a simple wrapper around LineIterator, and
|
|
|
31 supports utf8 lines only. Use LineIterator directly for utf16/32
|
|
|
32 support, or use the other tango.text.stream classes directly for
|
|
|
33 other tokenizing needs.
|
|
|
34
|
|
|
35 Note that this class is a true instance of InputStream, by way of
|
|
|
36 inheritance via the Iterator superclass.
