NAME

       Data::Stream::Bulk::Array - Data::Stream::Bulk wrapper for simple arrays.

VERSION

       version 0.11

SYNOPSIS

	       return Data::Stream::Bulk::Array->new(
		       array => @results,
	       );

DESCRIPTION

       This implementation of the Data::Stream::Bulk api wraps an array.

       The use case is to keep the consumer of the data set implementation agnostic so that it can deal with larger data sets if they are
       encountered, but still retain most of the simplicity when the current data set easily fits in memory.

ATTRIBUTES

       array
	   The array reference to wrap.

METHODS

       next
	   Returns the array reference on the first invocation, and nothing thereafter.

       is_done
	   Returns true if "next" has been called.

       list_cat
	   Squishes adjacent arrays into a new array.

       filter $filter
	   Immediately applies $filter to the internal array and returns $self.

       loaded
	   Returns true

NAME

       Data::Stream::Bulk::DBI - N-at-a-time iteration of DBI statement results.

VERSION

       version 0.11

SYNOPSIS

	       use Data::Stream::Bulk::DBI;

	       my $sth = $dbh->prepare("SELECT hate FROM sql"); # very big resultset
	       $sth->execute;

	       return Data::Stream::Bulk::DBI->new(
		       sth => $sth,
		       max_rows => $n, # how many at a time
		       slice => [ ... ], # if you want to pass the first param to fetchall_arrayref
	       );

DESCRIPTION

       This implementation of Data::Stream::Bulk api works with DBI statement handles, using "fetchall_arrayref" in DBI.

       It fetches "max_rows" at a time (defaults to 500).

ATTRIBUTES

       sth The statement handle to call "fetchall_arrayref" on.

       slice
	   Passed verbatim as the first param to "fetchall_arrayref". Should usually be "undef", provided for completetness.

       max_rows
	   The second param to "fetchall_arrayref". Controls the size of each buffer.

	   Defaults to 500.

METHODS

       get_more
	   See Data::Stream::Bulk::DoneFlag.

	   Calls "fetchall_arrayref" to get the next chunk of rows.

       all Calls "fetchall_arrayref" to get the raminder of the data (without specifying "max_rows").
