NAME

POE::Filter::Zlib - A POE filter wrapped around Compress::Zlib

VERSION

version 2.04

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.

"get_pending"

Returns any data in a filter's input buffer. The filter's input buffer is not cleared, however.

"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"

Sets the level of compression employed to the given value. If no value is supplied, returns the current level setting.
