 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.

inherited_from \BaseFilterReader::__construct()

Parameters

$in

\Reader

Creates a new ExpandProperties 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

objectA new filter based on this configuration, but filtering the specified reader

Close stream.

close() 
Inherited
inherited_from \FilterReader::close()
inherited_from \BaseFilterReader::close()

Exceptions

\IOException if there is an error closing stream

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

eof() : boolean
Inherited
inherited_from \BaseFilterReader::eof()

Returns

boolean

Returns the initialized status.

getInitialized() : boolean
Inherited
inherited_from \BaseFilterReader::getInitialized()

Returns

booleanwhether or not the filter is initialized

Returns the project this filter is part of.

getProject() : object
Inherited
inherited_from \BaseFilterReader::getProject()

Returns

objectThe project this filter is part of

Returns the filename, url, etc.

getResource() : string
Inherited

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

inherited_from \FilterReader::getResource()
inherited_from \BaseFilterReader::getResource()

Returns

string

Convenience method to support logging in filters.

log(string $msg, int $level) 
Inherited
inherited_from \BaseFilterReader::log()

Parameters

$msg

string

Message to log.

$level

int

Priority level.

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

mark() 
Inherited

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

inherited_from \Reader::mark()
inherited_from \FilterReader::mark()
inherited_from \BaseFilterReader::mark()

Whether marking is supported.

markSupported() : boolean
Inherited
inherited_from \Reader::markSupported()
inherited_from \FilterReader::markSupported()
inherited_from \BaseFilterReader::markSupported()

Returns

boolean

Returns the filtered stream.

read(\off $len) : mixed

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

exception IOException if the underlying stream throws an IOException during reading

Parameters

$len

\off

Offset at which to start storing characters.

Exceptions

\IOException If an I/O error occurs

Returns

mixedthe filtered stream, or -1 if the end of the resulting stream has been reached.

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

readLine() : \the
Inherited

The returned String retains the '\n'.

inherited_from \BaseFilterReader::readLine()

Exceptions

\IOException if the underlying reader throws one during reading

Returns

\theline read, or null if the end of the stream has already been reached

Is stream ready for reading.

ready() : boolean
Inherited
inherited_from \Reader::ready()
inherited_from \FilterReader::ready()
inherited_from \BaseFilterReader::ready()

Returns

boolean

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

reset() 
Inherited
inherited_from \FilterReader::reset()
inherited_from \BaseFilterReader::reset()

Sets the initialized status.

setInitialized(boolean $initialized) 
Inherited
inherited_from \BaseFilterReader::setInitialized()

Parameters

$initialized

boolean

Whether or not the filter is initialized.

Set level of log messages generated (default = info)

setLevel(string $level) 

Parameters

$level

string

Sets the project to work with.

setProject(\Project $project) 
Inherited
inherited_from \BaseFilterReader::setProject()

Parameters

$project

object

The project this filter is part of. Should not be null.

setReader()

setReader(\Reader $in) 
Inherited
inherited_from \FilterReader::setReader()
inherited_from \BaseFilterReader::setReader()

Parameters

$in

Move stream position relative to current pos.

skip(int $n) 
Inherited
inherited_from \FilterReader::skip()
inherited_from \BaseFilterReader::skip()

Parameters

$n

int
