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.
