Methods

__construct(
\Reader $in
=
null
)
:
voidConstructor used by Phing's introspection mechanism.
Inherited from: \BaseFilterReader::__construct()\BaseParamFilterReader::__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.
| Name | Type | Description |
|---|---|---|
| $in | \Reader |

chain(
object $reader
)
:
objectCreates a new StripLineBreaks using the passed in Reader for instantiation.
| Name | Type | Description |
|---|---|---|
| $reader | object | A Reader object providing the underlying stream. Must not be |
| Type | Description |
|---|---|
| object | A new filter based on this configuration, but filtering the specified reader |

close(
)
:
voidClose stream.
Inherited from: \FilterReader::close()\BaseFilterReader::close()\BaseParamFilterReader::close()| Exception | Description |
|---|---|
| \IOException | if there is an error closing stream |

eof(
)
:
booleanReturns whether the end of file has been reached with input stream.
Inherited from: \BaseFilterReader::eof()\BaseParamFilterReader::eof()| Type | Description |
|---|---|
| boolean |

getInitialized(
)
:
booleanReturns the initialized status.
Inherited from: \BaseFilterReader::getInitialized()\BaseParamFilterReader::getInitialized()| Type | Description |
|---|---|
| boolean | whether or not the filter is initialized |

getLineBreaks(
)
:
stringGets the line-breaking characters.
| Type | Description |
|---|---|
| string | A String containing all the characters that are considered as line-breaking. |

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

getResource(
)
:
stringReturns the filename, url, etc. that is being read from.
Inherited from: \FilterReader::getResource()\BaseFilterReader::getResource()\BaseParamFilterReader::getResource()This is critical for, e.g., ExpatParser's ability to know the filename that is throwing an ExpatParserException, etc.
| Type | Description |
|---|---|
| string |

log(
string $msg, int $level

|---|---|---|
| $msg | string | Message to log. |
| $level | int | Priority level. |

mark(
)
:
voidIf supported, places a "marker" (like a bookmark) at current stream position.
Inherited from: \Reader::mark()\FilterReader::mark()\BaseFilterReader::mark()\BaseParamFilterReader::mark()A subsequent call to reset() will move stream position back to last marker (if supported).

markSupported(
)
:
booleanWhether marking is supported.
Inherited from: \Reader::markSupported()\FilterReader::markSupported()\BaseFilterReader::markSupported()\BaseParamFilterReader::markSupported()| Type | Description |

read(
\off $len
=
null
)
:
mixedReturns the filtered stream, only including characters not in the set of line-breaking characters.
FIXME: Clean up this function signature, as it a) params aren't being used and b) it doesn't make much sense.
| Name | Type | Description |
|---|---|---|
| $len | \off | Offset at which to start storing characters. |
| Type | Description |
|---|---|
| mixed | the resulting stream, or -1 if the end of the resulting stream has been reached. |
| Exception | Description |
|---|---|
| \IOException | If an I/O error occurs |
- Exception
- IOException if the underlying stream throws an IOException during reading

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