Data::Stream::Bulk::DoneFlag(3pm) User Contributed Perl Documentation Data::Stream::Bulk::DoneFlag(3pm) NAME
Data::Stream::Bulk::DoneFlag - Implement the "is_done" method in terms of a flag VERSION
version 0.11 SYNOPSIS
package Data::Stream::Bulk::Blah; use Moose; with qw(Data::Stream::Bulk::DoneFlag); sub get_more { if ( my @more = more() ) { return @more; } else { return; } } DESCRIPTION
This role implements the "Data::Stream::Bulk" core API in terms of one method ("get_more"). As a convenience it calls "finished" when the stream is exhausted, so that cleanup may be done. This is used by classes like Data::Stream::Bulk::DBI, Data::Stream::Bulk::Callback. METHODS
is_done Returns the state of the iterator. next As long as the iterator is not yet done, calls "get_more". If "get_more" returned a false value instead of an array reference then "done" is set, "finished" is called, and this "next" does nothing on subsequent calls. finished A noop by default. Can be overridden if so desired. REQUIRED_METHODS get_more Returns the next block of data as an array ref, or a false value if no items are left. AUTHOR
