Methods

__construct(
          \Reader $in
              =
              null
          )
        
        :
          void

inherited

Constructor used by Phing's introspection mechanism.

Inherited from: \BaseFilterReader::__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

Parses parameters to add user defined regular expressions.

chain(
          object $reader
          )
        
        :
          object

Creates a new LineContainsRegExp 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

Returns

Type	Description
object	regExp The <code>regexp</code> element added.

          )
        
        :
          boolean

Returns the array of regular expressions which must be contained within a line read from the original stream in order for it to match this filter.

Returns

Type	Description
array	The array of regular expressions which must be contained within a line read from the original stream in order for it to match this filter. The returned object is "live" - in other words, changes made to the returned object are mirrored in the filter.

getResource(
          
          )
        
        :
          string

inherited

        :
          mixed

Returns all lines in a buffer that contain specified strings.

FIXME: Clean up this function signature, as it a) params aren't being used and b) it doesn't make much sense.
