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.
