Abstract

A computing device receives an object at runtime of a compiled application, wherein the object is a component of the application. The computing device generates a transactional proxy for the object, the transactional proxy including transactional logic, a transactional marker and a pointer to the object. The transactional proxy is passed to the application, wherein the application to make calls on the transactional proxy instead of on the object.

Claims

1. A computer implemented method, comprising:

receiving, by a computing device, an object at runtime of a compiled application, wherein the object is a component of the application;

generating a transactional proxy for the object by the computing device, the transactional proxy including transactional logic, a transactional marker and a pointer to the object; and

passing the transactional proxy to the application, wherein the application to make calls on the transactional proxy instead of on the object.

2. The method of claim 1, wherein the transaction logic includes logic for generating locks, for creating transaction logs, and for committing and aborting transactions, and wherein the transactional marker identifies to a transaction system that the transactional proxy is to be managed transactionally.

3. The method of claim 1, further comprising:

receiving a command by the transactional proxy to perform an action;

determining a locking strategy to use for the object based on the received command;

setting a lock for the object upon determining the locking strategy; and

forwarding the command to the object.

4. The method of claim 3, wherein the command is a command to modify a state of the object, the method further comprising:

determining that a write lock is appropriate;

saving the state of the object;

setting the write lock for the object; and

enrolling in an active transaction for the object.

5. The method of claim 3, wherein the command is a command to read a state of the object, the method further comprising:

determining that a read lock is appropriate; and

setting the read lock for the object.

6. The method of claim 1, further comprising:

receiving a command to generate the object;

generating the object using a first factory object; and

generating the transactional proxy for the object using a second factory object that wraps the first factory object.

7. The method of claim 1, further comprising:

receiving a command by the transactional proxy to perform an action;

setting a lock for the object based on a locking strategy that has been specified by an application optimizer, wherein the application optimizer monitored the behavior of the object to identify the locking strategy; and

forwarding the command to the object.

8. A computing apparatus, comprising:

a memory including instructions for a transactional object container; and

a processing device, connected with the memory, to execute the instructions, wherein the instructions cause the processing device to;

receive an object at runtime of a compiled application, wherein the object is a component of the application;

generate a transactional proxy for the object, the transactional proxy including transactional logic, a transactional marker and a pointer to the object; and

pass the transactional proxy to the application, wherein the application to make calls on the transactional proxy instead of on the object.

9. The computing apparatus of claim 8, wherein the transaction logic includes logic for generating locks, for creating transaction logs, and for committing and aborting transactions, and wherein the transactional marker identifies to a transaction system that the transactional proxy is to be managed transactionally.

10. The computing apparatus of claim 8, the instructions further to cause the processing device to:

receive a command by the transactional proxy to perform an action;

determine a locking strategy to use for the object based on the received command;

set a lock for the object upon determining the locking strategy; and

forward the command to the object.

11. The computing apparatus of claim 10, wherein the command is a command to modify a state of the object, the instructions further to cause the processor to:

determine that a write lock is appropriate;

save the state of the object;

set the write lock for the object; and

enroll in an active transaction for the object.

12. The computing apparatus of claim 10, wherein the command is a command to read a state of the object, the instructions further to cause the processor to:

determine that a read lock is appropriate; and

set the read lock for the object.

13. The computing apparatus of claim 8, the instructions further to cause the processor to:

receive a command to generate the object;

generate the object using a first factory object; and

generate the transactional proxy for the object using a second factory object that wraps the first factory object.

14. The computing apparatus of claim 8, the instructions further to cause the processor to:

receive a command by the transactional proxy to perform an action;

set a lock for the object based on a locking strategy that has been specified by an application optimizer, wherein the application optimizer monitored the behavior of the object to identify the locking strategy; and

forward the command to the object.

15. A computer readable storage medium including instructions that, when executed by a processing device, cause the processing device to perform a method comprising:

receiving, by a computing device, an object at runtime of a compiled application, wherein the object is a component of the application;

generating a transactional proxy for the object by the computing device, the transactional proxy including transactional logic, a transactional marker and a pointer to the object; and

passing the transactional proxy to the application, wherein the application to make calls on the transactional proxy instead of on the object.

16. The A computer readable storage medium of claim 15, wherein the transaction logic includes logic for generating locks, for creating transaction logs, and for committing and aborting transactions, and wherein the transactional marker identifies to a transaction system that the transactional proxy is to be managed transactionally.

17. The A computer readable storage medium of claim 16, the method further comprising:

receiving a command by the transactional proxy to perform an action;

determining a locking strategy to use for the object based on the received command;

setting a lock for the object upon determining the locking strategy; and

forwarding the command to the object.

18. The A computer readable storage medium of claim 17, wherein the command is a command to modify a state of the object, the method further comprising:

determining that a write lock is appropriate;

saving the state of the object;

setting the write lock for the object; and

enrolling in an active transaction for the object.

19. The A computer readable storage medium of claim 17, wherein the command is a command to read a state of the object, the method further comprising:

determining that a read lock is appropriate; and

setting the read lock for the object.

20. The A computer readable storage medium of claim 15, the method further comprising:

receiving a command to generate the object;

generating the object using a first factory object; and

generating the transactional proxy for the object using a second factory object that wraps the first factory object.

21. The A computer readable storage medium of claim 15, the method further comprising:

receiving a command by the transactional proxy to perform an action;

setting a lock for the object based on a locking strategy that has been specified by an application optimizer, wherein the application optimizer monitored the behavior of the object to identify the locking strategy; and

forwarding the command to the object.
