20090006067 | STAGE EVALUATION OF A STATE MACHINE - The present invention provides a method a system for facilitating enhanced processing of state diagrams in a state diagram environment. The method may include top-down processing a current state in a state diagram environment; determining whether processing of the current state results in an exception event; and passing the exception event to a superstate that includes the current state when it is determined that the current state results in an exception event. The superstate may be made the current state and it may be determined whether the current state can handle the exception event. When it is determined that the current state cannot handle the exception event, it may be determined whether the current state has a second superstate that includes the current state. An error event may be output from the state diagram environment when it is determined that the current state does not have a second superstate. | 01-01-2009 |
20090007079 | CALLING AN ENTITY OF A GRAPHICAL MODEL WITH A NON-GRAPHICAL ENTITY AND CALLING A NON-GRAPHICAL ENTITY OF A GRAPHICAL MODEL WITH A GRAPHICAL ENTITY - The present invention provides a graphical model in a computing environment, where the graphical model includes at least a caller entity. A call command associated with the caller entity is executed, where the call command includes at least a partial name of the callee entity. The at least one callee entity may be identified based on the partial name of the at least one callee entity provided in the call command. The at least one callee entity may then be called. | 01-01-2009 |
20090013307 | MULTI-RATE HIERARCHICAL STATE DIAGRAMS - Systems and methods are provided for a scheme and mechanism for performing static analysis of a sample time aware state diagram model to compute and propagate multiple samples rates associated with the state diagram model. A graphical intermediate representation of the state diagram model, such as a directed graph or control flow graph, is used to determine how the multiple sample rates are propagated via elements of the state diagram model. The graph provides a static representation of the control of flow, including alternative and/or conditional flow paths, of the state diagram model. The present invention determines the propagation of sample rates via analysis and traversal of the intermediate representation. By using the techniques of the present invention, a state diagram model may provide multiple sample rate outputs, such as by function calls and output signals to a graphical model, such as a model representing a dynamic system. | 01-08-2009 |
20090132993 | MODE-SWITCHED VARIABLE SIGNAL ATTRIBUTES IN BLOCK DIAGRAMS - A programming element is provided that defines model attributes in response to mode change events in a graphical modeling environment. Such definition may involve any signal attribute such as dimensions, data types, complexity and sample times. Events that trigger definition of model attributes may be explicit signaling events generated by other elements, elements within the block diagram programming environment, and elements external from the environment. Implicit events may also trigger definition of model attributes, such as a change of attribute in an input signal. | 05-21-2009 |
20120291003 | SYSTEM AND METHOD FOR CREATING AND USING GRAPHICAL OBJECT INSTANCES IN A STATECHART ENVIRONMENT - A method of providing multi-instantiable state templates to a statechart environment is discussed. The method includes the step of providing a graphical definition of an independent state machine object belonging to a statechart. The method further includes the step of instantiating a first instance and a second instance of the independent state machine object in the statechart. The method additionally includes the steps of starting execution of the first instance of the independent state machine object and then stopping execution of the first instance of the state machine object. Additionally, the method includes the step of starting the execution of the second instance of the independent state machine object in the state diagram. | 11-15-2012 |

20140351788 | RENAMING INSTANCES OF AN ENTITY IN A CODING ENVIRONMENT - Exemplary embodiments provide computer-implemented methods, computer-readable media, and systems for changing the identifier associated with an entity, such as a variable or function, in a portion of code. During editing, a reference may be maintained that identifies the location of each instance of the entity in the code. When the identifier associated with one instance of the entity is changed, the change in the identifier may be propagated throughout the code to change each instance of the identifier in the code. The identifier may be changed without interrupting the workflow of the user and without the need to change to a separate refactoring mode. In some embodiments, a syntactical analysis may be performed and some or all instances of the identifier may be changed based on one or more rules. | 11-27-2014 |
