filters/StripPhpComments.php
\StripPhpComments
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

__construct(
\Reader $in
=
null
)
:
voidConstructor used by Phing's introspection mechanism.
Inherited from: \BaseFilterReader::__construct()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.

| $in | \Reader |

chain(
\reader $reader
)
:
\aCreates a new StripPhpComments using the passed in Reader for instantiation.
| Name | Type | Description |

| $reader | \reader | A Reader object providing the underlying stream. Must not be |
| Type | Description |

| \a | new filter based on this configuration, but filtering the specified reader |

eof(
)
:
booleanReturns whether the end of file has been reached with input stream.

boolean
| Type | Description |
|---|---|
| boolean | whether or not the filter is initialized |

getProject(
)
:
objectReturns the project this filter is part of.
Inherited from: \BaseFilterReader::getProject()| Type | Description |
|---|---|
| object | The project this filter is part of |

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

read(
\off $len
=
null
)
:
\theReturns the stream without Php comments.
| Name | Type | Description |
|---|---|---|
| $len | \off | Offset at which to start storing characters. |
| Type | Description |
|---|---|
| \the | resulting stream, or -1 if the end of the resulting stream has been reached |
| Exception | Description |

| \IOException | if the underlying stream throws an IOException during reading |

readLine(
)

Inherited from: \BaseFilterReader::readLine()The returned String retains the '\n'.
| Type | Description |
|---|---|
| \the | line read, or <code>null</code> if the end of the stream has already been reached |
| Exception | Description |

| \IOException | if the underlying reader throws one during reading |

setInitialized(
