data::stream::bulk::filter

Data::Stream::Bulk::Filter(3pm) 			User Contributed Perl Documentation			   Data::Stream::Bulk::Filter(3pm)

NAME

       Data::Stream::Bulk::Filter - Streamed filtering (block oriented)

VERSION

       version 0.11

SYNOPSIS

	       use Data::Stream::Bulk::Filter;

	       Data::Stream::Bulk::Filter->new(
		       filter => sub { ... },
		       stream => $stream,
	       );

DESCRIPTION

       This class implements filtering of streams.

ATTRIBUTES

       filter
	   The code reference to apply to each block.

	   The block is passed to the filter both in $_ and as the first argument.

	   The return value should be an array reference. If no true value is returned the output stream does not end, but instead an empty block
	   is substituted (the parent stream controls when the stream is depleted).

       stream
	   The stream to be filtered

METHODS

       is_done
       loaded
	   Delegated to "stream"

       next
	   Calls "next" on "stream" and applies "filter" if a block was returned.
