 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()
inherited_from \BaseParamFilterReader::__construct()

Parameters

$in

\Reader

Creates a new ReplaceTokens 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()
inherited_from \BaseParamFilterReader::close()

Exceptions

\IOException if there is an error closing stream

Adds a token element to the map of tokens to replace.

createToken() : object

Returns

objectThe token added to the map of replacements. Must not be null.

Adds a token source to the sources of this filter.

createTokensource() : object

Returns

objectA Reference to the source just added.

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

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

Returns

boolean

Returns the "begin token" character.

getBeginToken() : string

Returns

stringThe character used to denote the beginning of a token.

Returns the "end token" character.

getEndToken() : \the

Returns

\thecharacter used to denote the beginning of a token

Returns the initialized status.

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

Returns

booleanwhether or not the filter is initialized

getParameters()

getParameters() 
Inherited
inherited_from \BaseParamFilterReader::getParameters()

Returns the project this filter is part of.

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

Returns

string

Returns the map of tokens which will be replaced.

getTokens() : array

; used by ReplaceTokens::chain()

Returns

arrayA map (String->String) of token keys to replacement values.

Returns the token sources used by this filter; used by ReplaceTokens::chain()

getTokensources() : array

Returns

array

Convenience method to support logging in filters.

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

Whether marking is supported.

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

Returns

boolean

Returns stream with tokens having been replaced with appropriate values.

read(\off $len) : mixed

If a replacement value is not found for a token, the token is left in the stream.

Parameters

$len

\off

Offset at which to start storing characters.

Exceptions

\IOException If an I/O error occurs

Returns

mixedfiltered stream, -1 on EOF.

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()
inherited_from \BaseParamFilterReader::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()
inherited_from \BaseParamFilterReader::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()
inherited_from \BaseParamFilterReader::reset()

Sets the "begin token" character.

setBeginToken(string $beginToken) 

Parameters
