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

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 <B>notB> 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.
