Filter which includes only those lines that contain all the user-specified
strings.
Example:
Or:
This will include only those lines that contain
foo
and
bar
.
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.
| inherited_from |
\BaseFilterReader::__construct() |
| inherited_from |
\BaseParamFilterReader::__construct() |
Parameters
Creates a new LineContains using the passed in
Reader for instantiation.
chain(\Reader $reader) : object
Parameters
$reader
objectA Reader object providing the underlying stream.
Must not be null.
Returns
objectA new filter based on this configuration, but filtering
the specified reader
Close stream.
close()

\BaseParamFilterReader::close() |
Exceptions
Adds a <code>contains</code> nested element.
createContains() : \Contains
Returns
\ContainsThe
contains element added.
Must not be
null.
Returns whether the end of file has been reached with input stream.
eof() : boolean

\BaseFilterReader::eof() |

\BaseParamFilterReader::eof() |
Returns
boolean
Returns the vector of words which must be contained within a line read
from the original stream in order for it to match this filter.
getContains() : array
Returns
arrayThe array of words 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 initialized status.

This is critical for, e.g., ExpatParser's ability to know
the filename that is throwing an ExpatParserException, etc.

\BaseFilterReader::log() |
| inherited_from |
\BaseParamFilterReader::log() |
Parameters
$msg
stringMessage to log.
$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).

Returns
boolean
Returns all lines in a buffer that contain specified strings.
read(\off $len) : mixed
FIXME: Clean up this function signature, as it a) params aren't being used
and b) it doesn't make much sense.
Parameters
$len
\offOffset at which to start storing characters.
Exceptions
Returns
mixedbuffer, -1 on EOF
[Deprecated.
readChar() : \the
For reference only, used to be read() method.]
Returns the next character in the filtered stream, only including
lines from the original stream which contain all of the specified words.
| exception |
IOException if the underlying stream throws an IOException
during reading |
Returns
\thenext character in 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'.

\BaseFilterReader::readLine() |
| inherited_from |
\BaseParamFilterReader::readLine() |
Exceptions
\IOException |
if the underlying reader throws one during
reading |
Returns
\theline read, or null if the end of the
stream has already been reached
Is stream ready for reading.
