__construct(
          \Reader $in

inherited

Constructor used by Phing's introspection mechanism.

Inherited from: \BaseFilterReader::__construct()\BaseParamFilterReader::__construct()

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.

Parameters

Name	Type	Description
$in	\Reader

_initialize(
          
          )
        
        :
          void

Initializes the prefix if it is available from the parameters.

chain(
          object $reader
          )
        
        :
          object

Creates a new PrefixLines filter using the passed in Reader for instantiation.

Parameters

Name	Type	Description
$reader	object	A Reader object providing the underlying stream. Must not be `null`.

Returns

Type	Description
object	A new filter based on this configuration, but filtering the specified reader
