Data::Stream::Bulk::Util(3pm) User Contributed Perl Documentation Data::Stream::Bulk::Util(3pm) NAME Data::Stream::Bulk::Util - Utility functions for Data::Stream::Bulk 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).
