Class GreedyResolver

java.lang.Object
org.glassfish.hk2.utilities.GreedyResolver
All Implemented Interfaces:
JustInTimeInjectionResolver

@Singleton @Visibility(LOCAL) public class GreedyResolver extends Object implements JustInTimeInjectionResolver
This is a greedy resolve that will add in any class that has failed to be resolved. It uses ServiceLocatorUtilities.addClasses(org.glassfish.hk2.api.ServiceLocator, Class...) in order to add classes, and hence will use the default class analyzer to discover injection points and constructors.

If the injected class is an interface the interface may use the GreedyDefaultImplementation in order to specify the class that should be used when another implementation of this interface cannot be found.

WARNING: This resolve should be used with care as it could cause unexpected class files to be instantiated by hk2

      public boolean justInTimeResolution(Injectee failedInjectionPoint)
      Description copied from interface: JustInTimeInjectionResolver
      This method will be called whenever an injection point cannot be resolved. If this method adds anything to the configuration it should return true. Otherwise it should return false. The injection point that failed to be resolved is given in failedInjectionPoint.

      If this method throws an exception that exception will be added to the set of exceptions in the MultiException that may be thrown from the injection resolver.

      This method can be called on multiple threads with different or the same Injectee. Therefore care must be taken in this method to not add the same descriptor more than once

      Specified by:
      justInTimeResolution in interface JustInTimeInjectionResolver
      Parameters:
      failedInjectionPoint - The injection point that failed to resolve
      Returns:
      true if this method has added a descriptor to the ServiceLocator which may be used to resolve the Injectee. False if this method did not add a descriptor to the ServiceLocator that might help resolve the injection point
