Methods

methodpublic__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
methodpublicchain( object $reader ) : object

Creates a new ExpandProperties 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
methodpublicclose( ) : void
inherited

Close stream.

Inherited from: \FilterReader::close()\BaseFilterReader::close()
Throws
Exception Description
\IOException if there is an error closing stream
methodpubliceof( ) : boolean
inherited

Returns whether the end of file has been reached with input stream.

Inherited from: \BaseFilterReader::eof()
Returns
Type Description
boolean
methodpublicgetInitialized( ) : boolean
inherited

Returns the initialized status.

Inherited from: \BaseFilterReader::getInitialized()
Returns
Type Description
boolean whether or not the filter is initialized
methodpublicgetProject( ) : object
inherited

Returns the project this filter is part of.

Inherited from: \BaseFilterReader::getProject()
Returns
Type Description
object The project this filter is part of
methodpublicgetResource( ) : string
inherited

Returns the filename, url, etc. that is being read from.

Inherited from: \FilterReader::getResource()\BaseFilterReader::getResource()

This is critical for, e.g., ExpatParser's ability to know the filename that is throwing an ExpatParserException, etc.

Returns
Type Description
string
methodpubliclog( string $msg, int $level = Project::MSG_INFO ) : void
inherited

Convenience method to support logging in filters.

Inherited from: \BaseFilterReader::log()
Parameters
Name Type Description
$msg string

Message to log.

$level int

Priority level.

methodpublicmark( ) : void
inherited

If supported, places a "marker" (like a bookmark) at current stream position.

Inherited from: \Reader::mark()\FilterReader::mark()\BaseFilterReader::mark()

A subsequent call to reset() will move stream position back to last marker (if supported).

methodpublicmarkSupported( ) : boolean
Returns
Type Description
boolean
methodpublicread( \off $len = null ) : mixed

Returns the filtered stream.

The original stream is first read in fully, and the Phing properties are expanded.

Parameters
Name Type Description
$len \off

Offset at which to start storing characters.

Returns
Type Description
mixed the filtered stream, or -1 if the end of the resulting stream has been reached.
Throws
Exception Description
\IOException If an I/O error occurs
Details
Exception
IOException if the underlying stream throws an IOException during reading  
methodpublicreadLine( ) : \the
inherited

Reads a line of text ending with '\n' (or until the end of the stream).

Inherited from: \BaseFilterReader::readLine()

The returned String retains the '\n'.

Returns
Type Description
\the line read, or <code>null</code> if the end of the stream has already been reached
Throws
Exception Description
\IOException if the underlying reader throws one during reading
methodpublicready( ) : boolean
inherited

Is stream ready for reading.

Inherited from: \Reader::ready()\FilterReader::ready()\BaseFilterReader::ready()
Returns
Type Description
boolean
methodpublicreset( ) : void
inherited

Reset the current position in stream to beginning or last mark (if supported).

Inherited from: \FilterReader::reset()\BaseFilterReader::reset()
methodpublicsetInitialized( boolean $initialized ) : void
inherited

Sets the initialized status.

Inherited from: \BaseFilterReader::setInitialized()
Parameters
