Intra-application messaging that is non-coupled may be facilitated through byte code injection. For example, a consumer class may be annotated with an annotation that describes data with which the function is to be called to consume data. A producer class may annotate a field/variable of an annotation to indicate that the data is generated by the producer class. At run time, a customized class loader scans each class as it is loaded for these annotations. When a consumer class is found, a byte code injector may write byte code that registers a consumer object instantiated from the consumer class to receive the data from a message router. When a producer class is found, a byte code injector may write byte code that notifies the message router that the data is available.

Annotation-based intra-application non-coupled messaging facilitated by byte-code injection and manipulation

The present disclosure is directed to persisting values in a computing environment, particularly using computer programs that run on a virtual machine. An illustrative method includes first launching a computer program, preferably within the environment of a virtual machine. The method further includes loading a plurality of classes associated with the computer program into memory by way of a special class loader. This class loader scans at least one class of classes loaded into memory for at least one persistence-annotated field within that class. The special class loader further writes byte code into a class that contains the at least one persistence-annotated field. The byte code that is added to the class causes a first object that is later instantiated from the at least one class to have the persistence-annotated field.

Apparatuses, methods and systems for persisting values in a computing environment

The present disclosure is directed to persisting values in a computing environment, particularly using computer programs that are configured to run on a virtual machine. An illustrative method includes first launching a computer program, preferably within the environment of a virtual machine. The method further includes loading a plurality of classes associated with the computer program into memory by way of a specially configured class loader. This class loader is configured to scan at least one class of classes loaded into memory for at least one persistence-annotated field within that class. The specially configured class loader is further configured to write byte code into a class that contains the at least one persistence-annotated field. The byte code that is added to the class is configured to cause a first object that is later instantiated from the at least one class to have the persistence-annotated field.
