Filter which includes only those lines that contain the user-specified
regular expression matching strings.
Example:
Or:
This will fetch all those lines that contain the pattern
foo
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 LineContainsRegExp 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

a line read from the original stream in order for it to match this
filter.

the returned object are mirrored in the filter.
Returns the filename, url, etc.
