      Description copied from interface: ServiceLocator
      Converts a descriptor to an ActiveDescriptor. Will use the registered HK2Loaders to perform this action. If no HK2Loader is available for the descriptor, will use the injectee to discover a classloader
      Specified by:
      reifyDescriptor in interface ServiceLocator
      Parameters:
      descriptor - The descriptor to convert, may not be null
      injectee - The injectee on behalf of whom this descriptor is being injected. May be null if the injectee is unknown
      Returns:

    • reifyDescriptor

      public ActiveDescriptor<?> reifyDescriptor(Descriptor descriptor) throws MultiException
      Description copied from interface: ServiceLocator
      Converts a descriptor to an ActiveDescriptor. Will use the registered HK2Loaders to perform this action

      public ActiveDescriptor<?> getInjecteeDescriptor(Injectee injectee) throws MultiException
      Description copied from interface: ServiceLocator
      This method will first find a descriptor for this injectee, and then reify that descriptor. If multiple descriptors are found, they will be reified in ranking order until an ActiveDescriptor matching the Injectee is found.

    • getLocatorId

      public long getLocatorId()
      Description copied from interface: ServiceLocator
      This returns the unique locator ID for this locator. The locator ID will be assigned at the time of creation and must be a monotonacally increasing number (starting at zero)
      Specified by:
      getLocatorId in interface ServiceLocator
      Returns:
      The identifier for this service locator

    • getDefaultClassAnalyzerName

      public String getDefaultClassAnalyzerName()
      Description copied from interface: ServiceLocator
      Gets the name of the default class analyzer service
      Specified by:
      getDefaultClassAnalyzerName in interface ServiceLocator
      Returns:
      The name of the default class analyzer. Will not return null

    • setDefaultClassAnalyzerName

      public void setDefaultClassAnalyzerName(String defaultClassAnalyzer)
      Description copied from interface: ServiceLocator
      Sets the name of the default class analyzer that should be used for all Descriptors that return null as their class analyzer. If null is given then the default class analyzer name of ClassAnalyzer.DEFAULT_IMPLEMENTATION_NAME will be used
      Specified by:
      setDefaultClassAnalyzerName in interface ServiceLocator
      Parameters:
      defaultClassAnalyzer - The possibly null name of the default class analyzer (the class analyzer that will be used if a descriptor has not explicitly set the name of its class analyzer)

    • getDefaultUnqualified

      public Unqualified getDefaultUnqualified()
      Description copied from interface: ServiceLocator
      This returns the default Unqualified annotation that will be put on all injection points that do not have any qualifiers. This Unqualified will not be returned by the Injectee.getUnqualified() method as it is considered to be the systems default Unqualified annotation. If an injection point has its own Unqualified annotation returned from Injectee.getUnqualified() then that one takes precedence over this one. Further any injection point that is a IterableProvider will not have the default unqualified applied to it
      Specified by:
      getDefaultUnqualified in interface ServiceLocator
      Returns:
      The Unqualified annotation that will be (virtually) put on injection points that have no qualifiers and no other Unqualified annotation. If null then this ServiceLocator has no default Unqualified annotation to be applied

    • setDefaultUnqualified

      public void setDefaultUnqualified(Unqualified unqualified)
      Description copied from interface: ServiceLocator
      This sets the default Unqualified annotation that will be put on all injection points that do not have any qualifiers. This Unqualified will not be returned by the Injectee.getUnqualified() method as it is considered to be the systems default Unqualified annotation. If an injection point has its own Unqualified annotation returned from Injectee.getUnqualified() then that one takes precedence over this one. Further any injection point that is a IterableProvider will not have the default unqualified applied to it

      This method may be called at any time, but will only affect lookups and injections that have not yet occurred

      Specified by:
      setDefaultUnqualified in interface ServiceLocator
      Parameters:
      unqualified - The Unqualified annotation that will be (virtually) put on injection points that have no qualifiers and no other Unqualified annotation. If null then this ServiceLocator has no default Unqualified annotation to be applied

    • getParent

      public ServiceLocator getParent()
      Description copied from interface: ServiceLocator
      Gets the parent service locator for this locator
      Specified by:
      getParent in interface ServiceLocator
      Returns:
      The parent service locator for this locator, or null if this service locator does not have a parent

    • getNeutralContextClassLoader

      public boolean getNeutralContextClassLoader()
      Description copied from interface: ServiceLocator
      This returns the value of neutralContextClassLoader. If this value is true then HK2 will ensure that the context class loader on the thread is maintained whenever hk2 calls into user code. If this value is false then the value of the context class loader on the thread may be changed by the code hk2 is calling.

      When set to false this value is used to increase performance since getting and setting the context class loader can be expensive. However, if the user code being called by hk2 may change the context class loader of the thread, this value should be true to ensure that tricky and hard to find bugs don't arise when this thread is used for other purposes later on

      All new ServiceLocator implementation have this value initially set to true

      Specified by:
      getNeutralContextClassLoader in interface ServiceLocator
      Returns:
      If true hk2 will ensure that the context class loader cannot be changed by user code. If false hk2 will not modify the context class loader of the thread when user code has finished

    • setNeutralContextClassLoader

      public void setNeutralContextClassLoader(boolean neutralContextClassLoader)
      Description copied from interface: ServiceLocator
      This sets the value of neutralContextClassLoader. If this value is true then HK2 will ensure that the context class loader on the thread is maintained whenever hk2 calls into user code. If this value is false then the value of the context class loader on the thread may be changed by the code hk2 is calling.

      When set to false this value is used to increase performance since getting and setting the context class loader can be expensive. However, if the user code being called by hk2 may change the context class loader of the thread, this value should be true to ensure that tricky and hard to find bugs don't arise when this thread is used for other purposes later on

      All new ServiceLocator implementation have this value initially set to true

      Specified by:
      setNeutralContextClassLoader in interface ServiceLocator
      Parameters:
      neutralContextClassLoader - true if hk2 should ensure context class loader neutrality, false if hk2 should not change the context class loader on the thread around user code calls
