Data::Stream::Bulk::Filter - Streamed filtering (block oriented)
use Data::Stream::Bulk::Filter;
Data::Stream::Bulk::Filter->new(
filter => sub { ... },
stream => $stream,
);
This class implements filtering of streams.
- 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
- is_done
- loaded
- Delegated to "stream"
- next
- Calls "next" on
"stream" and applies
"filter" if a block was returned.
