POE::Filter::Zlib(3) User Contributed Perl Documentation POE::Filter::Zlib(3)NAMEPOE::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" ),
DESCRIPTIONPOE::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.
