Instance Method Details

#addition_requires_reconfiguration? ⇒ Boolean

Whether this service can be added dynamically (i.e. without requiring a reconfigure)

Returns:

  • (Boolean)

#remove_when_unused? ⇒ Boolean

Whether this service must be removed when unused

Returns:

  • (Boolean)

# File 'lib/syskit/models/bound_dynamic_data_service.rb', line 22

def remove_when_unused?
    dynamic_service.remove_when_unused?
end

#same_service?(other) ⇒ Boolean

Whether two services are the same service bound to two different interfaces

When subclassing, the services are promoted to the new component interface that is being accessed, so in effect when one does

bound_m = task_m.test_srv
sub_m = task_m.mew_submodel
sub_bound_m = bound_m.test_srv

Then sub_bound_m != bound_m as sub_bound_m is bound to sub_m and bound_m is bound to task_m. This is important, as we sometimes want to compare services including which interface they're bound to.

However, in some cases, we want to know whether two services are actually issues from the same service definition, i.e. have been promoted from the same service. This method performs that comparison

Parameters:

Returns:

  • (Boolean)
