NAME
POE::Filter::Zlib::Stream - A POE filter wrapped around Compress::Zlib deflate and inflate.
SYNOPSIS
use POE::Filter::Zlib::Stream;
my $filter = POE::Filter::Zlib::Stream->new( deflateopts => { -Level => 9 } );
my $scalar = 'Blah Blah Blah';
my $compressed_array = $filter->put( [ $scalar ] );
my $uncompressed_array = $filter->get( $compressed_array );
use POE qw(Filter::Stackable Filter::Line Filter::Zlib::Stream);
my ($filter) = POE::Filter::Stackable->new();
$filter->push( POE::Filter::Zlib::Stream->new(),
POE::Filter::Line->new( InputRegexp => '\015?\012', OutputLiteral => "\015\012" ),DESCRIPTION
POE::Filter::Zlib::Stream provides a POE filter for performing compression/uncompression using Compress::Zlib. It is suitable for use with POE::Filter::Stackable.
Unlike POE::Filter::Zlib this filter uses deflate and inflate, not the higher level compress and uncompress.
Ideal for streaming compressed data over sockets.
CONSTRUCTOR
- new
-
Creates a new POE::Filter::Zlib::Stream object. Takes some optional arguments:
"deflateopts", a hashref of options to be passed to deflateInit(); "inflateopts", a hashref of options to be passed to inflateInit();Consult Compress::Zlib for more detail regarding these options.
METHODS
- get
- get_one_start
- get_one
-
Takes an arrayref which is contains streams of compressed input. Returns an arrayref of uncompressed streams.
- put
-
Takes an arrayref containing streams of uncompressed output, returns an arrayref of compressed streams.
- clone
-
Makes a copy of the filter, and clears the copy's buffer.
