Attaches a prefix to every line.
Methods
Constructor used by Phing's introspection mechanism.
__construct(\Reader $in)
Inherited
The original filter reader is only used for chaining
purposes, never for filtering purposes (and indeed
it would be useless for filtering purposes, as it has
no real data to filter). ChainedReaderHelper uses
this placeholder instance to create a chain of real filters.

\BaseFilterReader::__construct() |

\BaseParamFilterReader::__construct() |
Parameters
Creates a new PrefixLines filter using the passed in
Reader for instantiation.
chain(\Reader $reader) : object
Parameters
$reader
object
A Reader object providing the underlying stream. Must not be null
.
Returns
object
A new filter based on this configuration, but filtering
the specified reader

read(\off $len) : mixed
FIXME: Clean up this function signature, as it a) params aren't being used
and b) it doesn't make much sense.
Parameters
$len
\off
Offset at which to start storing characters.
Exceptions
Returns
mixed
