NAME
Data::Stream::Bulk::Util - Utility functions for Data::Stream::BulkSYNOPSIS
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).
