NAME
POE::Filter::Zlib - A POE filter wrapped around Compress::ZlibSYNOPSIS
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.
