NAME
POE::Filter::Zlib - A POE filter wrapped around Compress::Zlib
SYNOPSIS
use POE::Filter::Zlib;
my $filter = POE::Filter::Zlib->new();
my $scalar = 'Blah Blah Blah';
my $compressed_array = $filter->put( [ $scalar ] );
my $uncompressed_array = $filter->get( $compressed_array );
use POE qw(Filter::Stackable Filter::Line Filter::Zlib);
my ($filter) = POE::Filter::Stackable->new();
$filter->push( POE::Filter::Zlib->new(),
POE::Filter::Line->new( InputRegexp => '\015?\012', OutputLiteral => "\015\012" ),
DESCRIPTION
POE::Filter::Zlib provides a POE filter for performing compression/uncompression using Compress::Zlib. It is suitable for use with POE::Filter::Stackable.
This filter is not ideal for streaming compressed data over sockets etc. as it employs compress and uncompress zlib functions.
POE::Filter::Zlib::Stream is recommended for that type of activity.
CONSTRUCTOR
- new
-
Creates a new POE::Filter::Zlib object. Takes one optional argument,
'level': the level of compression to employ.
Consult Compress::Zlib for details.
METHODS
- get
- get_one_start
- get_one
-
Takes an arrayref which is contains lines of compressed input. Returns an arrayref of uncompressed lines.
- put
-
Takes an arrayref containing lines of uncompressed output, returns an arrayref of compressed lines.
- clone
-
Makes a copy of the filter, and clears the copy's buffer.
- level
