This is a Php comment and string stripper reader that filters
those lexical tokens out for purposes of simple Php parsing.
(if you have more complex Php parsing needs, use a real lexer).
Since this class heavily relies on the single char read function,
you are reccomended to make it work on top of a buffered reader.
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.

\BaseFilterReader::__construct() |
Parameters
Creates a new StripPhpComments using the passed in
Reader for instantiation.
chain(\Reader $reader) : \a
Parameters
$reader
\reader
A Reader object providing the underlying stream. Must not be null
.
Returns
\a
new filter based on this configuration, but filtering
the specified reader
Close stream.
close()

\FilterReader::close() |
inherited_from |
\BaseFilterReader::close() |
Exceptions
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
boolean
whether or not the filter is initialized
Returns the project this filter is part of.
getProject() : object
Inherited
inherited_from |
\BaseFilterReader::getProject() |
Returns
object
The 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).

\BaseFilterReader::markSupported() |
Returns
boolean
Returns the stream without Php comments.
read(\off $len) : \the
FIXME: Clean up this function signature, as it a) params aren't being used
and b) it doesn't make much sense.
Parameters
$len
\off
Offset at which to start storing characters.
Exceptions
\IOException |
if the underlying stream throws an IOException
during reading |
Returns
\the
resulting 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
\the
line read, or null
if the end of the
stream has already been reached
Is stream ready for reading.
