Methods

Performs lookup on key and returns appropriate replacement string.

replaceTokenCallback(array $matches) : string

access	private

Arguments

$matches

array

Array of 1 el containing key to search for.

Response

string

Text with which to replace key or value of key if none is found.

Read data from source.

read(int $len = null)

inherited abstract

If length is specified, then only that number of chars is read, otherwise stream is read until EOF.

Arguments

$len

int

Sets the "begin token" character.

setBeginToken(string $beginToken)

Arguments

$beginToken

string

the character used to denote the beginning of a token.

Returns the "begin token" character.

getBeginToken() : string

Response

string

The character used to denote the beginning of a token.

Sets the "end token" character.

setEndToken(string $endToken)

Arguments

$endToken

string

the character used to denote the end of a token

Returns the "end token" character.

getEndToken() : \the

Response

\the

character used to denote the beginning of a token

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

createToken() : object

Response

object

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

Adds a token source to the sources of this filter.

createTokensource() : object

Response

object

A Reference to the source just added.

Sets the map of tokens to replace.

setTokens($tokens)

; used by ReplaceTokens::chain()

Arguments

$tokens

Returns the map of tokens which will be replaced.

getTokens() : array

; used by ReplaceTokens::chain()

Response

array

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

Sets the tokensources to use; used by ReplaceTokens::chain()

setTokensources($sources)

Arguments

$sources

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

getTokensources() : array

Response

array

Creates a new ReplaceTokens using the passed in Reader for instantiation.

chain(\Reader $reader) : object

Arguments

$reader

\Reader

Response

object

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

Initializes tokens and loads the replacee-replacer hashtable.

_initialize()

This method is only called when this filter is used through a tag in build file.

Returns the initialized status.

getInitialized() : boolean

inherited

Response

boolean

whether or not the filter is initialized

Sets the initialized status.

setInitialized(boolean $initialized)

inherited

Arguments

$initialized

boolean

Whether or not the filter is initialized.

Sets the project to work with.

setProject(object $project)

inherited

Arguments

$project

object

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

Returns the project this filter is part of.

getProject() : object

inherited

Response

object

The project this filter is part of

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

readLine() : \the

inherited

The returned String retains the '\n'.

throws	if the underlying reader throws one during reading

Response

\the

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

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

eof() : boolean

inherited

Response

boolean

Convenience method to support logging in filters.

log(string $msg, int $level = \Project::MSG_INFO)

inherited

Arguments

$msg

string

Message to log.

$level

int

Priority level.

setReader

setReader(\Reader $in)

inherited

Arguments

$in

\Reader

Move stream position relative to current pos.

skip(int $n)

inherited

Arguments

$n

int

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

reset()

inherited

Close stream.

close()

inherited abstract

throws	if there is an error closing stream

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

getResource() : string

inherited abstract

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

Response

string

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).

Whether marking is supported.

markSupported() : boolean

inherited

Response

boolean

Is stream ready for reading.

ready() : boolean

inherited

Response

boolean
