Method and system for implementing an interrupt handler

A computer-implemented method for handling an interrupt in a Java operating system comprising a single execution flow scheduler, the execution flow scheduler comprising a single Java native execution flow activation method that causes a context switch to an execution flow context specified when the execution flow activation method is invoked, the computer-implemented method comprising:

• instantiating an interrupt handler object for the interrupt using an interrupt handler class that extends an execution flow class, defines a handler method for the interrupt, and defines an execution flow execution method that overrides an execution flow execution method defined in the execution flow class and comprises one or more instructions to invoke the handler method, wherein an execution flow context for the handler method is created;
• invoking the Java native execution flow activation method of the execution flow scheduler to switch to the handler execution flow context when the interrupt is signaled;
• and
• invoking the execution flow execution method of the interrupt handler class to initiate execution of the handler method after switching to the handler execution flow context.

A non-transitory computer-readable medium storing a Java software system comprising a single execution flow scheduler, the execution flow scheduler comprising a single Java native execution flow activation method that causes a context switch to an execution flow context specified when the execution flow activation method is invoked, wherein when the Java software system is executed by a processor, a method for handling an interrupt is performed, the method comprising:

• instantiating an interrupt handler object for the interrupt using an interrupt handler class that extends an execution flow class, defines a handler method for the interrupt, and defines an execution flow execution method that overrides an execution flow execution method defined in the execution flow class and comprises one or more instructions to invoke the handler method, wherein an execution flow context for the handler method is created;
• invoking the Java native execution flow activation method of the execution flow scheduler to switch to the handler execution flow context when the interrupt is signaled;
• and
• invoking the execution flow execution method of the interrupt handler class to initiate execution of the handler method after switching to the handler execution flow context.

A system, comprising:

• a processor;
• a Java software system configured to execute on the processor, the Java software system comprising a Java virtual machine and a single execution flow scheduler, the execution flow scheduler comprising a single Java native execution flow activation method that causes a context switch to an execution flow context specified when the execution flow activation method is invoked, wherein the Java software system is configured
• to instantiate an interrupt handler object for an interrupt using an interrupt handler class that extends an execution flow class, defines a handler method for the interrupt, and defines an execution flow execution method that overrides an execution flow execution method defined in the execution flow class and comprises one or more instructions to invoke the handler method, wherein an execution flow context for the handler method is created;
• to invoke the Java native execution flow activation method of the execution flow scheduler to switch to the handler execution flow context when the interrupt is signaled;
• and
• to invoke the execution flow execution method of the interrupt handler class to initiate execution of the handler method after switching to the handler execution flow context.
