Automated detection and implementation of state and object modifications
View Patent ↗Automatic detection and implementation of modifications to an application are described. A new base model of the application is generated using the edited version of the application. This base model is simulated to a selected state, resulting in a new presentation model that includes a tree of multiple objects described by the new base model at the selected state, and a pointer for each node of the tree that points back to the associated node in the new base model. The pointers of each node of the new presentation model are compared to the nodes of the previous presentation model of the application and then replaced with those corresponding nodes in the previous presentation model when the nodes are equivalent. Otherwise, the nodes of the new presentation model are maintained.
1. A computer-implemented method, comprising:
accessing a first base model of an application, the first base model representing code of the application;
receiving input defining a change to the code;
in response to the change to the code, creating an edited base model of the application representing the code of the application as changed;
creating a new stateful model of the application by processing the edited base model using a transform to simulate the edited base model in a state, the new stateful model representing a first appearance of the application when in the state;
accessing a previous stateful model of the application, the previous stateful model representing a simulation of the first base model in the state and representing a second appearance of the application, prior to the change, when in the state;
comparing the new stateful model to the previous stateful model to identify a change between the new stateful model and the previous stateful model; and
providing data identifying the change between the new stateful model and the previous stateful model.
2. The method of claim 1 , wherein providing data identifying the change comprises providing a change list.
3. The method of claim 1 , wherein the state is one of a plurality of states defined by the code of the application.
4. The method of claim 1 , wherein the code of the first base model is extensible markup language (XML) and wherein the transform to simulate the edited base model to a state is processed using extensible stylesheet language (XSL).
5. The method of claim 1 , wherein the data identifying the change is an edited stateful model representing a simulation of the edited base model, wherein the edited stateful model is constructed from both the previous stateful model and from the new stateful model.
6. A computer program product comprising a non-transitory computer-readable medium embodying program instructions, the program instructions comprising:
program instructions for accessing code of an application;
program instructions for creating a first base model of the application using the code of the application;
program instructions for receiving input defining a change to the code of the application;
program instructions for creating, in response to the change to the code of the application, an edited base model of the application representing the code of the application as changed;
program instructions for creating a new stateful model of the application by processing the edited base model using a transform to simulate the edited base model in a state, the new stateful model representing a first appearance of the application when in the state;
program instructions for accessing a previous stateful model of the application, the previous stateful model representing a simulation of the first base model in the state and representing a second appearance of the application, prior to the change, when in the state;
program instructions for comparing the new stateful model to a previous stateful model to identify a change between the new stateful model and the previous stateful model; and
program instructions for providing data identifying the change between the new stateful model and the previous stateful model.
7. The computer program product of claim 6 , wherein providing data identifying the change comprises providing a change list.
8. The computer program product of claim 6 , wherein the state is one of a plurality of states defined by the code of the application.
9. A system comprising a processor and a non-transitory computer-readable medium, wherein the non-transitory computer-readable medium embodies one or more program components that configure the computing system to carry out operations comprising:
accessing code of an application;
creating a first base model of the application using the code, the base model representing the underlying code of the application;
after creating, receiving input defining a change to the code;
in response to the change to the code, creating an edited base model of the application representing the underlying code of the application as changed;
creating a new stateful model of the application by processing the edited base model using a transform to simulate the edited base model in a state, the new stateful model representing a first appearance of the application when in the state;
accessing a previous stateful model of the application, the previous stateful model representing a simulation of the first base model in the state and representing a second appearance of the application, prior to the change, when in the state;
comparing the new stateful model to the previous stateful model to identify a change between the new stateful model and the previous stateful model; and
providing data identifying the change between the new stateful model and the previous stateful model.
10. The computing system set forth in claim 9 , wherein providing data identifying the change comprises providing a change list.
11. The computing system set forth in claim 9 , wherein the state is one of a plurality of states defined by the code of the application.
