Abstract
Abstract A system and method are disclosed for a common set of Component Peer classes for the Java abstract windowing toolkit (AWT). The native methods employed by the various platform-specific versions of a Peer class are similar in operation, but contain differences in the source code of the C/C++ functions that implement them. Consequently, they represent distinct bodies of software, which must be supported and maintained separately. The present invention provides a basis for replacing the diverse versions of the Component Peers with a single set, employing a standardized set of native methods. This results in a unique codebase for the Component Peers, across all the supported operating systems, thereby reducing the effort required to maintain and upgrade the software.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
102 words
A computer system, comprising: an operating environment containing a processor and an operating system; a compiler adapted to compile source code into object code specific to the operating environment; a software interface between an application program and the operating environment, wherein the software interface is written in source code and is substantially independent of the operating environment, wherein the software interface is adapted to produce a body of object code when the software inferface is compiled by the compiler, and wherein the body of object code contains instructions executable by the processor for eliciting a set of actions from the operating environment.
Claim 2
Dependent Claim
102 words
A computer system, comprising: an operating environment containing a processor and an operating system; a compiler adapted to compile source code into object code specific to the operating environment; a software interface between an application program and the operating environment, wherein the software interface is written in source code and is substantially independent of the operating environment, wherein the software interface is adapted to produce a body of object code when the software inferface is compiled by the compiler, and wherein the body of object code contains instructions executable by the processor for eliciting a set of actions from the operating environment.
Claim 3
Dependent Claim
66 words
The computer system as recited in claim 1 , further comprising a second compiler adapted to compile the source code into a second body of object code specific to a second operating environment, distinct from the first, and containing instructions executable by a second processor for eliciting substantially the same set of actions from the second operating environment as those elicited from the first operating environment.
Claim 4
Dependent Claim
42 words
The computer system as recited in claim 1 , wherein the application program further comprises a Java application running within the operating environment and adapted to utilize the instructions contained in the object code to elicit pre-defined actions from the operating environment.
Claim 5
Dependent Claim
38 words
The computer system as recited in claim 1 , wherein the software interface further comprises a plurality of software elements that associate desired actions elicited from the operating environment with at least some of the standard Java classes.
Claim 6
Dependent Claim
44 words
The computer system as recited in claim 4 , wherein the Java application program interacts with the operating system by employing standard Java classes with which desired actions on the part of the operating system have been associated by the plurality of software elements.
Claim 7
Dependent Claim
19 words
The computer system as recited in claim 5 , wherein the software interface comprises the abstract windowing toolkit (AWT).
Claim 8
Dependent Claim
22 words
The computer system as recited in claim 6 , wherein the plurality of software elements comprises the Java AWT Component Peer classes.
Claim 9
Dependent Claim
22 words
The computer system as recited in claim 1 , wherein the operating system comprises a Windows, Unix or OS/2 computer operating system.
Claim 10
Dependent Claim
30 words
The computer system as recited in claim 1 , wherein the source code in which the software interface is written comprises instructions in the Java, C and C++ programming languages.
Claim 11
Independent Claim
90 words
A method for creating a common interface to any of a plurality of operating environments, wherein an operating environment comprises a processor and an operating system, the method comprising: defining a software interface between an application program and the operating environment by a body of source code substantially independent of any operating environment; and deriving a body of object code by compiling the body of source code that defines the software interface, such that the object code contains instructions for eliciting a set of actions from a particular operating environment.
Claim 12
Independent Claim
90 words
A method for creating a common interface to any of a plurality of operating environments, wherein an operating environment comprises a processor and an operating system, the method comprising: defining a software interface between an application program and the operating environment by a body of source code substantially independent of any operating environment; and deriving a body of object code by compiling the body of source code that defines the software interface, such that the object code contains instructions for eliciting a set of actions from a particular operating environment.
Claim 13
Dependent Claim
22 words
The method as recited in claim 10 , wherein the body of source code comprises instructions written in the Java programming language.
Claim 14
Dependent Claim
23 words
The method as recited in claim 11 , wherein the body of source code further comprises instructions written in the C/C++ programming language.
Claim 15
Dependent Claim
32 words
The method as recited in claim 10 , wherein the application program further comprises a Java application running within the operating environment and initiating execution of instructions contained within the object code.
Claim 16
Dependent Claim
25 words
The method as recited in claim 10 , wherein the body of object code comprises at least one of the Java AWT Component Peer classes.
Claim 17
Dependent Claim
16 words
The system as recited in claim 10 , wherein the operating environment further comprises a JVM.
Claim 18
Dependent Claim
73 words
A computer-readable storage device, comprising: a software interface between a Java application program and an operating environment containing a processor and an operating system, wherein the software interface is written in source code and is substantially independent of any particular operating environment; and a body of object code, produced when the source code for the software interface is compiled, and containing instructions for eliciting a set of actions from a particular operating environment.
Claim 19
Dependent Claim
73 words
A computer-readable storage device, comprising: a software interface between a Java application program and an operating environment containing a processor and an operating system, wherein the software interface is written in source code and is substantially independent of any particular operating environment; and a body of object code, produced when the source code for the software interface is compiled, and containing instructions for eliciting a set of actions from a particular operating environment.
Claim 20
Dependent Claim
25 words
The computer-readable storage device as recited in claim 16 , wherein the software interface comprises at least one of the Java AWT Component Peer classes.
Claim 21
Dependent Claim
14 words
The computer-readable storage device as recited in claim 16 , further comprising a JVM.
