Methods

__construct

__construct(\Reader $in = null) 
inherited

Arguments

$in

\Reader

Parses parameters to add user defined regular expressions.

_initialize() 

Close stream.

close() 
inherited abstract
throws

if there is an error closing stream

Adds a <code>regexp</code> element.

createRegexp() : object

Response

object

regExp The regexp element added.

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

eof() : boolean
inherited

Response

boolean

Returns the initialized status.

getInitialized() : boolean
inherited

Response

boolean

whether or not the filter is initialized

Returns the parameters to be used by this filter.

getParameters() : array
inherited

Response

array

the parameters to be used by this filter

Returns the project this filter is part of.

getProject() : object
inherited

Response

object

The project this filter is part of

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.

getRegexps() : array

Response

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.

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

Convenience method to support logging in filters.

log(string $msg, integer $level = \Project::MSG_INFO) : void
inherited

Arguments

$msg

string

Message to log.

$level

integer

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).

Whether marking is supported.

markSupported() : boolean
inherited

Response

boolean

Read data from source.

read(integer $len = null) 
inherited abstract

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

Arguments

$len

integer

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

readLine() : string
inherited

The returned String retains the '\n'.

throws

if the underlying reader throws one during

                reading

Response

string

the line read, or null if the end of the

        stream has already been reached

Is stream ready for reading.

ready() : boolean
inherited

Response

boolean

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

reset() 
inherited

Sets the initialized status.

setInitialized(boolean $initialized) 
inherited

Arguments

$initialized

boolean

Whether or not the filter is initialized.

Sets the parameters used by this filter, and sets the filter to an uninitialized status.

setParameters(array $parameters) : void
inherited
throws

Arguments

$parameters

array

Array of parameters to be used by this filter.

         Should not be <code>null</code>.

Sets the project to work with.

setProject(object|\Project $project) 
inherited

Arguments

$project

object|\Project

The project this filter is part of.

                   Should not be <code>null</code>.

setReader

setReader(\Reader $in) 
inherited

Arguments

$in

\Reader

Move stream position relative to current pos.

skip(integer $n) 
inherited

Arguments

$n

integer
