Data::Stream::Bulk::Filter - Streamed filtering (block oriented)
version 0.11
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.
