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.
