NAME ^

Context::Set::Storage::Split - Split storage of Context::Set accross different Context::Set::Storage's

MANUAL ^

Contexts are dispatched accross different storage according to a set of rules.

A rule should have:

  - name : This is free and mandatory.
  - test: A Code Ref that test a given context (see example).
  - storage: Where to store the contexts that pass the test. Should be an instance of any subclass of L<Context::Set::Storage>

Rules are tested in the order of the definition, so the default one should go at the end of the list. If you don't specify a default, this storage will die if no rule matches the context you make it manage.

For example:

   $users_store and $general_store are instances of L<Context::Set::Storage>

   ## Store the contexts unders 'users' in a special store, all the rest in a general one.
   my $split_store = Context::Set::Storage::Split->new({
                                                     rules => [{
                                                                name => 'users_specific',
                                                                test => sub{ shift->is_inside('users'); },
                                                                storage => $users_store
                                                               },
                                                               {
                                                                name => 'default',
                                                                test => sub{ 1; },
                                                                storage => $general_store
                                                               }]
                                                    });
