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.
