NAME

       Data::Stream::Bulk::Path::Class - Path::Class::Dir traversal

VERSION

       version 0.11

SYNOPSIS

	       use Data::Stream::Bulk::Path::Class;

	       my $dir = Data::Stream::Bulk::Path::Class->new(
		       dir => Path::Class::Dir->new( ... ),
	       );

DESCRIPTION

       This stream produces depth or breadth first traversal order recursion through Path::Class::Dir objects.

       Items are read iteratively, and a stack of open directory handles is used to keep track of state.

ATTRIBUTES

       chunk_size
	   Defaults to 250.

       depth_first
	   Chooses between depth first and breadth first traversal order.

       only_files
	   If true only Path::Class::File items will be returned in the output streams (no directories).

METHODS

       is_done
	   Returns true when no more files are left to iterate.

       next
	   Returns the next chunk of Path::Class objects

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).
