Hash::Util::FieldHash::Compat(3pm) User Contributed Perl Documentation Hash::Util::FieldHash::Compat(3pm)NAME
Hash::Util::FieldHash::Compat - Use Hash::Util::FieldHash or ties, depending on availability.
SYNOPSIS
use Hash::Util::FieldHash::Compat;
# pretend you are using L<Hash::Util::FieldHash>
# under older perls it'll be Tie::RefHash::Weak instead (slower, but same behavior)
DESCRIPTION
Under older perls this module provides a drop in compatible api to Hash::Util::FieldHash using perltie. When Hash::Util::FieldHash is
available it will use that instead.
This way code requiring field hashes can benefit from fast, robust field hashes on Perl 5.10 and newer, but still run on older perls that
don't ship with that module.
See Hash::Util::FieldHash for all the details of the API.
SEE ALSO

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).
