Class AutowiringImpl

java.lang.Object
  org.apache.hivemind.service.impl.AutowiringImpl

All Implemented Interfaces:

Autowiring

public class AutowiringImpl
extends java.lang.Object
implements Autowiring

Implementation of Autowiring. Skips properties of primitive type and the standard java data types (String, Double etc.). Properties that are already assigned are skipped too. Delegates the autowiring to implementations of AutowiringStrategy. If errors occur they are passed to an ErrorHandler. Depending on its implementation the wiring either continues with the next property or an exception is thrown.
