NAME

Data::Stream::Bulk::Util - Utility functions for Data::Stream::Bulk

CONTENTS

VERSION

version 0.11

SYNOPSIS



        use Data::Stream::Bulk::Util qw(array);

        use namespace::clean;

        # Wrap a list in L<Data::Stream::Bulk::Array>
        return bulk(qw(foo bar gorch baz));

        # return an empty resultset
        return nil();



DESCRIPTION

This module exports convenience functions for use with Data::Stream::Bulk.

EXPORTS

Sub::Exporter is used to create the import routine, and all of its aliasing/currying goodness is of course supported.
nil Creates a new Data::Stream::Bulk::Nil object.

Takes no arguments.

bulk @items Creates a new Data::Stream::Bulk::Array wrapping @items.
cat @streams Concatenate several streams together.

Returns nil if no arguments are provided.

filter { ... } $stream Calls filter on $stream with the provided filter.
unique $stream Filter the stream to remove duplicates.

Note that memory use may potentially scale to O(k) where k is the number of distinct items, because this is implemented in terms of a seen hash.

In the future this will be optimized to be iterative for sorted streams.

References are keyed by their refaddr (see id in Hash::Util::FieldHash).
