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.
METHODS
new
Creates a new POE::Filter::Zlib object. Takes one optional argument, 'level': the level of compression to employ. Consult Compress::Zlib for details.
get
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.
level
Sets the level of compression employed to the given value. If no value is supplied, returns the current level setting.
