KiokuDB::Role::ID::Content - Content dependent object IDs
version 0.55
package BLOB; use Moose; use Digest::SHA1; with qw(KiokuDB::Role::ID::Content); sub kiokudb_object_id { my $self = shift; sha1_hex($self->data); } has data => ( isa => "Str", is => "ro", required => 1, );
This is a role for KiokuDB::Role::Immutable objects whose IDs depend on their content, or in other words content addressable objects.
A canonical example is a string identified by its SHA-1 hash, as is demonstrated in the "SYNOPSIS".
Objects which do this role are never updated in the database just like KiokuDB::Role::Immutable objects.
Additionally, it is not an error to insert such objects twice since the objects are assumed to be identical.
