 Instances of classes that depend on automatic DI are only ready to be used after the DI has completed. Annotating methods in the injectee class with the @[PostConstruct]@ metadata causes them to be invoked directly after all injections have completed and it is safe to use the instance. Multiple methods can be invoked in a defined order by using the @order@ parameter: @[PostConstruct(order=1)]@.
 
+h3. Querying for injection mapping existence
+
+As of version 1.5, SwiftSuspenders supports querying for the existence of mapping rules for any request using @Injector#hasMapping@.
+@hasMapping@ expects a class or an interface and optionally a name for the mapping and returns @true@ if a request for this class/ name combination can be satisfied. Otherwise, it returns @false@.
+
+h3. Directly applying injection mappings
+
+As of version 1.5, SwiftSuspenders supports directly applying injection mappings using @Injector#getMappingResponse@.
+@getMappingResponse@ expects a class or an interface and optionally a name for the mapping and returns the mapping's result if one is defined. Otherwise, an exception is thrown.
+
+The returned value depends on the mapping defined for the relevant request. E.g., if a singleton mapping has been defined for the request, the shared singleton instance will be returned instead of creating a new instance of the class.

 h3. Error handling
 
 If a mapping for a requested injection is not found, an exception containing the target class and the requested property type.
