----------------------------------------
Summary: Allow external entity to interact during the service
resolution
Key: FELIX-4120
URL: https://issues.apache.org/jira/browse/FELIX-4120
Project: Felix
Issue Type: New Feature
Components: iPOJO
Affects Versions: ipojo-runtime-1.10
Reporter: Clement Escoffier
Assignee: Clement Escoffier
Fix For: ipojo-runtime-1.10.1
When iPOJO is tracking services, it should let extenral entities to intercept
service resolution to determine the services to use.
With this feature it is possible to:
* mark services
* change filters, even build filter chains
* update the selected services dynamically
Two interception are supported:
* tracking : allow filtering out and transforming references. Transformation
changes the properties of the reference
* ranking : sort the set of references
Both interceptors are exposed as services and are plugged on the service
dependency dynamically. Obviously they can leave and arrive at runtime. To
manage a dependency, they expose a service property named 'target' which is a
LDAP filter selecting a set of dependencies.
