Executing cross-cutting concerns for client-server remote procedure calls

摘要

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.

主权项

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.
