Data::Stream::Bulk::Filter->new(

DESCRIPTION

ATTRIBUTES
filter
The code reference to apply to each block.
The block is passed to the filter both in $_ and as the first

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.
