Interface BeanConfiguration

All Known Implementing Classes:
BasicBeanConfiguration
public interface BeanConfiguration
API for a configuration object.

This API can be used to publish configuration information from one OSGi bundle to another, without knowing the actual implementation of any target service. For example, imagine two serial IO implementation bundles exist, but the SolarNode application does not know which one the user will choose to use. In this case, the SolarNode application bundle need not import either of the IO implementation bundles directly. Instead it can publish a BeanConfiguration service that the IO implementations can register to use to configure itself.

The BeanConfigurationServiceRegistrationListener provides an easy way for implementation bundles to bind to BeanConfiguration services at runtime and dynamically publish services based on this configuration.

    • getConfiguration

      Map<String,Object> getConfiguration()
      Get the configuration properties as a Map.
      Returns:
      Map of configuration properties

    • getAttributes

      Map<String,Object> getAttributes()
      Get configuration attributes as a Map.

      These attributes are not configuration properties that get applied directly to services, but can be used to distinguish one configuration from another.

      Returns:
      Map of configuration attributes

    • getOrdering

      Integer getOrdering()
      Get a configuration ordering.

      The ordering can be used to treat similar configurations in an ordered fashion.

      Returns:
      an ordering
