Abstract

Systems and methods for implementing cross-cutting actions that cut across many remote procedure calls (RPCs) in an interactive application, such as location-based parallel reality game are provided. In particular, one or more decorators can be associated in a source file, such as a Java source file, with a remote procedure call class defining a plurality of RPC methods for the interactive application. Each decorator can be a set of instructions that gets executed before and after an RPC method and addresses concerns that cut across a plurality of RPC methods for the interactive application.

Claims

1. A computer-implemented method of executing cross-cutting actions across a plurality of remote procedure calls in an interactive application, comprising:

processing a source file defining a remote procedure call class specifying a plurality of remote procedure call methods, the source file comprising a decorator annotation annotating the remote procedure call class with one or more decorators such that each of the one or more decorators applies to each of a plurality of remote procedure call methods specified in the remote procedure call class, each of the one or more decorators specifying a cross-cutting action for the interactive application; and

executing the cross-cutting actions specified in each of the decorators in conjunction with executing at least one of the plurality of remote procedure call methods specified in the remote procedure call class

wherein the decorators are specified in the source file in the decorator annotation annotating the remote procedure call class.

2. The computer-implemented method of claim 1, wherein the source file is a Java source file.

3. The computer-implemented method of claim 1, wherein each decorator is specified as a decorator class in the decorator annotation, each decorator class implementing a marker interface.

4. The computer-implemented method of claim 3, wherein each decorator class defines a before method and an after method associated with the cross-cutting action.

5. The computer-implemented method of claim 4, wherein the before method and the after method are specified as annotations in the decorator class.

6. The computer-implemented method of claim 4, wherein executing the cross-cutting actions specified in each of the decorators in conjunction with executing the remote procedure call method comprises:

executing the before method defined for each decorator class specified in the decorator annotation associated with the remote procedure call class;

subsequent to executing the before method for each decorator class, executing the at least one remote procedure call method defined in the remote procedure call class; and

subsequent to executing the remote procedure call method, executing the after method defined for each decorator class specified in the decoration annotation associated with the remote procedure call class.

8. The computer-implemented method of claim 1, wherein the interactive application is a location-based parallel reality game.

9. The computer-implemented method of claim 8, wherein the one or more cross-cutting actions comprise at least one or more of recording a player'"'"'s location information, recording the time at which the player last connected, updating virtual energy associated with the player, updating player damage, or verifying log in information.

7. The computer-implemented method of 4, wherein the before method comprises initiating an asynchronous data store query associated with the cross-cutting action and the after method comprises completing the asynchronous data store query associated with the cross-cutting action.

10. A computing device having one or more processors and one or more non-transitory computer-readable media, the one or more non-transitory computer-readable media storing computer-readable instructions for executing a plurality of remote procedure call methods for an interactive application, such as a location based-parallel reality game, the one or more computer-readable media storing a source file defining a remote procedure call class specifying a plurality of remote procedure call methods, the source file annotating the remote procedure call class with one or more decorators such that each of the one or more decorators applies to each of a plurality of remote procedure call methods specified in the remote procedure call class, each of the one or more decorators specifying a cross-cutting action for the interactive application, wherein the one or more processors are configured to execute the cross-cutting actions specified in each of the decorators in conjunction with executing a remote procedure call method specified in the remote procedure call class

wherein each decorator is specified in the source file in the decorator annotation annotating the remote procedure call class.

11. The computing device of claim 10, wherein the source file is a Java source file.

12. The computing device of claim 10, wherein each decorator is specified as a decorator class that defines a before method and an after method.

13. The computing device of claim 12, wherein the before method and the after method are specified as annotations in the source file.

14. The computing device of claim 12, wherein the one or more processors are configured to execute the cross-cutting actions specified in each of the decorators in conjunction with executing the remote procedure call method by:

executing the before method defined for each decorator specified in the decorator annotation annotating the remote procedure call class;

subsequent to executing the before method for each decorator, executing the at least one remote procedure call method defined in the remote procedure call class; and

subsequent to executing the remote procedure call method, executing the after method defined for each decorator specified in the decoration annotation annotating the remote procedure call class.

15. A tangible, non-transitory computer-readable medium storing computer-storing computer-readable instructions that when executed by the one or more processors cause the one or more processors to perform operations, the operations comprising:

processing a source file defining a remote procedure call class specifying a plurality of remote procedure call methods, the source file annotating the remote procedure call class with one or more decorators such that each of the one or more decorators applies to each of a plurality of remote procedure call methods specified in the remote procedure call class, each of the one or more decorators specifying a cross-cutting action for the interactive application; and

executing the cross-cutting actions specified in each of the decorators in conjunction with executing a remote procedure call method specified in the remote procedure call class

wherein the decorators are specified in the source file in the decorator annotation annotating the remote procedure call class.

16. The tangible, non-transitory computer-readable medium of claim 15, wherein each decorator is specified as a decorator class that defines a before method and an after method.

17. The tangible, non-transitory computer-readable medium of claim 16, wherein the before method and the after method are specified as annotations in the source file.

18. The tangible, non-transitory computer-readable medium of claim 17, wherein the operation of executing the cross-cutting actions specified in each of the decorators in conjunction with executing the remote procedure call method comprises:

executing the before method defined for each decorator specified in the decorator annotation annotating the remote procedure call class;

subsequent to executing the before method for each decorator, executing the at least one remote procedure call method defined in the remote procedure call class; and

subsequent to executing the remote procedure call method, executing the after method defined for each decorator specified in the decoration annotation annotating the remote procedure call class.
