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();
- flushtype
- The type of flush to use when flushing the compressed data. Defaults to Z_SYNC_FLUSH so you get a single stream, but if there is a POE::Filter::Zlib on the other end, you want to set this to Z_FINISH.
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.
- 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 streams of uncompressed output, returns an arrayref of compressed streams.
- clone
- Makes a copy of the filter, and clears the copy's buffer.
