Data::Stream::Bulk::Filter(3) User Contributed Perl Documentation Data::Stream::Bulk::Filter(3)

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.
