Methods


__construct(
\Reader $in
=
null
)
:
void
Constructor 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
)
:
object
Creates 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(
)
:
void
Close stream.
Inherited from: \FilterReader::close()\BaseFilterReader::close()\BaseParamFilterReader::close()Exception | Description |
---|---|
\IOException | if there is an error closing stream |


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


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


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


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


getResource(
)
:
string
Returns 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.

mark(
)
:
void
If 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(
)
:
boolean
Whether marking is supported.

read(
\off $len
=
null
)
:
mixed
Returns 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 |
