A graphical user interface (GUI) scheduler program is provided for modeling business workflow processes. The GUI scheduler program includes tools to allow a user to create a schedule for business workflow processes based on a set of rules defined by the GUI scheduler program. The rules facilitate deadlock not occurring within the schedule. The program provides tools for creating and defining message flows between entities. Additionally, the program provides tools that allow a user to define a binding between the schedule and components, such as COM components, script components, message queues and other workflow schedules. The scheduler program allows a user to define actions and group actions into transactions using simple GUI scheduling tools. The schedule can then be converted to executable code in a variety of forms such as XML, C, C+ and C++. The executable code can then be converted or interpreted for running the schedule.

The invention relates to optimizing software code execution during state transitions. The system handles changes in execution context using differential rule checking techniques. For instance, when a thread executing in a data processing system changes state, its new state may be subject to different rules than its previous state. To enforce these rules, the thread may be associated with software code that causes certain restrictions, such as memory restrictions, to be applied to the thread. In an interpretive environment, this can be implemented by detecting a state transition in an active thread, and responding to the state transition by associating the thread with a dispatch table that reflects its state change. The dispatch table may cause the thread to be associated with code that enforces those restrictions. In one example, different dispatch tables can be provided, each table reflecting a different state of a thread, and each causing a thread to be subject to different restrictions. In another example, the same dispatch table can be rewritten to accommodate the changed state of the thread.

Indirect method invocation of methods that only return constant values is optimized using fetching operations and return constant tables. Such method calls can be optimized if all possible method calls via the call site instruction return a constant value and have no side effects. Each constant return value is loaded from a return constant table, and method invocation is eliminated. If all possible target methods in a program result in a constant return value and have no side effects, an associated virtual function dispatch table (vtable) may be used as the return constant table. Furthermore, control operation optimization may be applied to identify type constraints, based on one or more possible type-dependent constant return values from an indirect method invocation. An optimizer identifies and maps between a restricted set of values and an associated restricted set of types on which execution code may operate relative to a given control operation. The type constraints are used to optimize the associated execution code by filtering propagation of runtime type approximations for optimization.

A technique for implementing a data processor to determine if an exception has been thrown. Specifically, the technique may be used in an interpretive environment where a table known as a bytecode (upcode) dispatch table is used. The dispatch table contains addresses for code that implements each bytecode. When the interpreter executes normally, these addresses point to the basic target machine code for executing each bytecode. However, when an Asynchrounously Interrupted Exception (AIE) is thrown, then the dispatch table is repopulated so that all byte codes point to routines that can handle the exception. These may point to a routine, such as an athrow, that has been extended to handle the special case of the AIE. Alternatively, the rewritten table can point to a routine that is specifically written to handle the firing of an AIE. The table contents are restored to their prior state once the exception handling is complete. The scheme may also be implemented non-rewriting of the table if a thread is in a non-Asynchronous Transfer of Control (to defer ATC) deferred state.
