      • configure

        protected abstract void configure()
        Implement to provide binding definitions using the exposed binding methods.
      • bind

        public <T> ActiveDescriptor<T> bind​(Descriptor descriptor)
        This method will bind the given descriptor to this Module. If the descriptor given is not an ActiveDescriptor then a non-reified ActiveDescriptor will be returned with the system provided fields set. If the descriptor given is a reified ActiveDescriptor then the descriptor returned will be a reified ActiveDescriptor that takes all values except for the id from the given descriptor. A deep copy will be made of the incoming descriptor

        This method can be called only in the execution context of the configure() method.

        Specified by:
        bind in interface DynamicConfiguration
        Parameters:
        descriptor - May not be null. Will be used to derive the various key fields associated with the given provider
        Returns:
        The entry as added to the service registry, with fields of the Descriptor filled in by the system as appropriate

        This adds two active descriptors to the system based completely on the analysis of the given Factory class. The Factory class itself and all interfaces marked contract will be in the list of advertised services. The scope and qualifiers will be taken from the annotations on the class. The annotations on the Factory.provide() method will provide the scope and qualifiers of the service produced by the Factory

        This method can be called only in the execution context of the configure() method.

        Specified by:
        addActiveFactoryDescriptor in interface DynamicConfiguration
        Parameters:
        rawFactoryClass - The class to analyze, must not be null
        Returns:
        The factory descriptors that have been added to the system, with all fields filled in based on the rawFactoryClass

      • addUnbindFilter

        public void addUnbindFilter​(Filter unbindFilter)
                             throws IllegalArgumentException
        This filter will added to the list of filters in this Configuration that will determine which Descriptors will be removed from the system. Only services directly from this Configuration objects' associated ServiceLocator will be given to this Filter (it will not be given descriptors from the ServiceLocators parent). The descriptors passed into this filter may be cast to ActiveDescriptor. The descriptors passed into this filter may or may not have been reified. This filter should not reify passed in descriptors.

        And descriptor for which this filter returns true will be removed from the ServiceLocator prior to any additions that are performed with this Configuration object. Hence a Configuration can remove and add a descriptor of the same type in one commit.

        In order to unbind a filter the caller of commit must pass the LOOKUP validators and the UNBIND validators.

        This method can be called only in the execution context of the configure() method.

        Specified by:
        addUnbindFilter in interface DynamicConfiguration
        Parameters:
        unbindFilter - This filter will be added to the list of filters that this configuration object will use to determine which descriptors to unbind from the system. May not be null
        Throws:
        IllegalArgumentException - if unbindFilter is null
      • addIdempotentFilter

        public void addIdempotentFilter​(Filter... unbindFilter)
                                 throws IllegalArgumentException
        At commit time all idempotent filters in this dynamic configuration will be run against all validation-visible descriptors. If any of the idempotent filters are a match then the commit will FAIL and none of the descriptors in this DynamicConfiguration will be added or removed. The idempotent filters will be run under the same lock as the commit, and hence can guarantee true idempotency of the transaction.

        The normal use case for the use of this filter is to ensure that a service is only added once to the ServiceLocator, even when multiple threads may be attempting to add the same service

        The filter passed in should not do any change to the set of descriptors itself, any attempt to do so will leave the system in an inconsistent state. IndexedFilter is supported and is the normal use of an idempotent filter, though it is not required

        This method can be called only in the execution context of the configure() method.

        Specified by:
        addIdempotentFilter in interface DynamicConfiguration
        Parameters:
        unbindFilter - A non-null idempotent filter to use during commit. If any descriptors match the filter, the commit will fail
        Throws:
        IllegalArgumentException - If any of the filters are null
      • registerTwoPhaseResources

        public void registerTwoPhaseResources​(TwoPhaseResource... resources)
        Description copied from interface: DynamicConfiguration
        Registers two-phase resources in the order in which they are to run. Subsequent calls to this method will add resources at the end of the existing list
        Specified by:
        registerTwoPhaseResources in interface DynamicConfiguration
        Parameters:
        resources - A list of resources to add to this dynamic configuration
      • commit

        public void commit()
                    throws MultiException
        This causes the configuration to get committed. This method may only be called once

        This method can be called only in the execution context of the configure() method.

        Specified by:
        commit in interface DynamicConfiguration
        Throws:
        MultiException - If errors were found in the commit process
      • install

        public final void install​(Binder... binders)
        Adds all binding definitions from the binders to the binding configuration.
        Parameters:
        binders - binders whose binding definitions should be configured.
