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.
