NAME

       KiokuDB::Backend::Role::Scan - Root set iteration

VERSION

       version 0.57

SYNOPSIS

           with qw(KiokuDB::Backend::Role::Scan);

           sub all_entries {
               my $self = shift;

               # return all root set entries
               return Data::Stream::Bulk::Foo->new(...);
           }

DESCRIPTION

       This is a role for iterative scanning of all entries in a backend.

       It is used for database backups, and various other tasks.

REQUIRED METHODS

       all_entries
           Should return a Data::Stream::Bulk stream enumerating all entries in the database.

OPTIONAL METHODS

       These method have default implementations defined in terms of "all_entries" but maybe
       overridden if there is a more optimal solution than just filtering that stream.

       root_entries
           Should return a Data::Stream::Bulk of just the root entries.

       child_entries
           Should return a Data::Stream::Bulk of everything but the root entries.
