Abstract

Determining how to perform operations specified in executable code. A method may include accessing a language context. The language context is related to a consumer location in executable code. The language context specifies an operation to be performed on one or more objects. The method includes sending a message requesting information about how to perform the operation on the one or more objects. A meta-object is received. The meta-object includes or produces executable code, that when executed performs the operation on the one or more objects.

Claims

1. In a computing environment, a method of determining how to perform operations specified in executable code, the method comprising:

accessing a language context, wherein the language context is related to a consumer location in executable code, wherein the consumer location specifies an operation to be performed on one or more objects;

sending a message requesting information about how to perform the operation on the one or more objects; and

receiving a meta-object, the meta-object comprising or capable of producing executable code, that when executed performs the operation on the one or more objects.

2. The method of claim 1, wherein sending a message requesting information about how to perform the operation comprises sending one or more of the arguments for the operation.

3. The method of claim 1, wherein receiving a meta-object comprises receiving a meta-object with information specified by the language context.

4. The method of claim 3, wherein receiving a meta-object with information specified by the language context comprises receiving a meta-object created by the language context that includes or is capable of producing executable code created based on one or more meta-objects received from the one or more objects.

5. The method of claim 4, wherein to create the meta-object created by the language context that includes or is capable of producing executable code created based on one or more meta-objects received from the one or more objects, the language context performs the following:

receiving a request from the one or more objects for one or more requirements of the language context as the requirements relate to the operation;

sending a message including one or more requirements of the language context as the requirements relate to the operation to the one or more objects; and

receiving one or more meta-objects from the one or more objects, the one or more meta-objects from the one or more objects comprising or capable of producing executable code configured to take into account the one or more requirements of the language context.

6. The method of claim 1, wherein receiving a meta-object comprises receiving a meta-object with information specified by one of the one or more objects.

7. The method of claim 6, wherein the one or more objects are written in a different language than the language context.

8. The method of claim 1, wherein receiving a meta-object comprises receiving a meta-object with information specified by a helper object provided by a dynamic language runtime.

9. The method of claim 1, wherein receiving a meta-object comprises receiving a meta-object with information specified by an extension.

10. The method of claim 1, wherein the meta-object comprises a test specifying one or more conditions for when the executable code in the meta-object should be executed.

11. The method of claim 10, further comprising:

caching the meta-object;

determining that the specified one or more conditions have been met; and

as a result, executing the executable code in the meta-object on a subsequent request to execute the operation based on determining that the specified one or more conditions have been met so as to avoid a subsequent request for information about how to perform the operation.

12. In a computing environment, a method of determining how to perform operations specified in executable code, the method comprising:

accessing a language context, wherein the language context is related to a consumer location in executable code, wherein the consumer location in executable code specifies an operation to be performed on one or more objects;

accessing a meta-object, the meta-object comprising or producing executable code, that when executed performs the operation on the one or more objects; and

executing the code in or produced by the meta object to perform the operation.

13. The method of claim 12, wherein the language context and the one or more meta-objects are implemented in a plurality of different languages.

14. The method of claim 12, wherein the executable code in or produced by the meta-object comprises code generated from information received from at least one of the one or more objects.

15. The method of claim 12, wherein the executable code in or produced by the meta-object comprises code generated from information received from a helper object of a dynamic language runtime framework in which the language context is executed.

16. The method of claim 12, wherein the executable code in or produced by the meta-object comprises code generated from information received from an extension object of a language executing the language context.

17. The method of claim 12, wherein the meta-object comprises or produces a test specifying one or more conditions for when the executable code in the meta-object should be executed, the method further comprising:

caching the test and the executable code in or produced by the meta-object.

18. The method of claim 17, further comprising:

determining that the specified one or more conditions have been met; and

as a result, executing the executable code in or produced by the meta-object on a subsequent request to execute the operation based on determining that the specified one or more conditions have been met.

19. The method of claim 17, further comprising:

determining that the test will never succeed; and

as a result flushing the test from the cache.

20. In a computing environment, the computing environment comprising a dynamic language runtime, the dynamic language runtime comprising a framework for executing executable code, a method of determining how to perform operations specified in the executable code, the method comprising:

accessing a language context, wherein the language context is related to a consumer location in executable code, wherein the consumer location in executable code specifies an operation to be performed on one or more objects, wherein at least one of the one or more objects is written in a different language than the language context;

requesting information about how to perform the operation on the one or more objects; and

in response to requesting information about how to perform the operation, receiving a meta-object, wherein the meta-object comprises or produces;

executable code, that when executed performs the operation on the one or more objects;

test information specifying one or more conditions for using the executable code in the meta-object when subsequent instances of the operation are encountered; and

wherein the executable code is generated from information stored by the language context, and information received by the language context querying one or more of the one or more objects themselves for information about how to perform the operation, extension objects to the dynamic language runtime including information about how to perform the operation, or a language including the language context, wherein the language comprises objects including information about how to perform the operation.
