System and method for reducing the static footprint of mixed-language JAVA classes

摘要

A system and a method for minimizing the functionality-gap between JAVA™ and native platforms while keeping the impact on each JAVA™ API static footprint as small as possible. A JAVA™ Runtime Dynamic Invocation API is used for low-level bridging between JAVA™ and C/C++, enabling the dynamic invocation of native C/C++ functions and C++ class/object methods from the JAVA™ side without adding any additional ad hoc implemented native code to the overall JAVA™ component implementation. Thereby, the need to write new native code when implementing a JAVA™ component that needs to invoke some native functionality is reduced.

1. A method of reducing the static footprint of mixed-language classes in an electronic device, comprising:
providing a runtime dynamic invocation (RDI) application program interface (API) configured to interact with applications and native APIs; and permitting the applications to manipulate native language entities at ran-time via the RDI API using a plurality of interfaces, without necessitating additional application-specific native code, wherein the native language entities available for manipulation by the applications include objects, primitive data-type variables, structures, and function pointers.
