Abstract

Modelling a serialized object stream can include receiving a stream of bytes corresponding to the serialized form of a first object, creating an empty initial model for containing a generic object and a generic class, and, upon detection of a class from the stream, constructing a corresponding generic class object in the model using a processor. Upon detection of a new object from the stream, a corresponding generic object in the model can be constructed. Further objects and classes in the model that are associated with the generic objects and classes can be referenced.

Claims

1. A method for modelling a serialized object stream, comprising:

receiving a stream of bytes corresponding to the serialized form of a first object;

creating an empty initial model for containing a generic object and a generic class;

upon detection of a class from said stream, constructing a corresponding generic class object in the model using a processor;

upon detection of a new object from said stream, constructing a corresponding generic object in the model; and

referencing further objects and classes in the model that are associated with the generic objects and classes.

2. The method of claim 1, further comprising:

dynamically building a model as a content representation of the serialized object stream without referencing a library of definitions of classes of the serialized object; and

dynamically building a class directory as classes are discovered in the stream.

3. The method of claim 2, wherein the model includes a sequence representing an ordered list of objects, classes and data found in the stream in the order of occurrence in the stream.

4. The method of claim 1, wherein upon detection of a class from said stream, adding a class description to a class pool.

5. The method of claim 1, wherein upon detection of a new object from said stream, adding the new object to an object pool.

6. The method of claim 5, wherein upon detection of a new object from said stream, constructing an object reference pointing to the new object in the object pool.

7. The method of claim 5, wherein upon detection of a previous object from said stream, constructing an object reference pointing to an existing object in the object pool.

8. The method of claim 1, further comprising:

reproducing a serialized object stream from a model by iterating through a sequence list of the model and serializing each data, object and class in order.

9. The method of claim 8, further comprising:

adding a new object item if a referenced object has not already been serialized; and

adding a previous object item if a referenced object has already been serialized.

10. The method of claim 1, further comprising:

displaying an instance of a model; and

enabling a user to edit the field content of the model.

11. The method of claim 10, wherein displaying an instance of a model displays the model in tree form with fields presented as children of the object to which the fields belong.

12. The method of claim 10, wherein displaying an instance of a model includes representing objects in the form of one of the group of:

a flat list, grouped by classes, or arranged as a reference tree.

13. A system for modelling a serialized object stream, comprising:

a processor configured to perform operations comprising;

receiving a stream of bytes corresponding to the serialized form of a first object;

creating an empty initial model for containing a generic object and a generic class;

upon detection of a class from said stream, constructing a corresponding generic class object in the model;

upon detection of a new object from said stream, constructing a corresponding generic object in the model; and

referencing further objects and classes in the model that are associated with the generic objects and classes.

14. The system of claim 13, wherein the processor is further configured to perform operations comprising:

dynamically building a model as a content representation of the serialized object stream without referencing a library of definitions of classes of the serialized object; and

dynamically building a class directory as classes are discovered in the stream.

15. The system of claim 14, wherein the model includes a sequence representing an ordered list of objects, classes and data found in the stream in the order of occurrence in the stream.

16. The system of claim 13, wherein the processor is further configured to perform operations comprising:

reproducing a serialized object stream from a model by iterating through a sequence list of the model and serializing each data, object and class in order.

17. The system of claim 13, wherein the processor is further configured to perform operations comprising:

displaying an instance of a model and enabling a user to edit the field content of the model.

18. A computer program product for modelling a serialized object stream, comprising:

a computer readable storage medium having program code embodied therewith, the program code executable by a processor to perform operations comprising;

receiving a stream of bytes corresponding to the serialized form of a first object;

creating an empty initial model for containing a generic object and a generic class;

upon detection of a class from said stream, constricting a corresponding generic class object in the model;

upon detection of a new object from said stream, constructing a corresponding generic object in the model; and

referencing further objects and classes in the model that are associated with the generic objects and classes.

19. The computer program product of claim 18, wherein the program code is further executable by a processor to perform operations comprising:

dynamically building a model as a content representation of the serialized object stream without referencing a library of definitions of classes of the serialized object; and

dynamically building a class directory as classes are discovered in the stream.

20. The computer program product of claim 19, wherein the model includes a sequence representing an ordered list of objects, classes and data found in the stream in the order of occurrence in the stream.

21. The computer program product of claim 18, wherein the program code is further executable by a processor to perform operations comprising:

reproducing a serialized object stream from a model by iterating through a sequence list of the model and serializing each data, object and class in order.

22. The computer program product as claimed in claim 18, wherein the program code is further executable by a processor to perform operations comprising:

displaying an instance of a model and enabling a user to edit the field content of the model.
