ContinueInstruction()

Method Summary

java.util.Map	getDescriptionProperties() Get a description as a set of properties of primitive types such as String, Integer, etc.
void	process(ProcedurePlan env) Allow this instruction to do whatever processing it needs, and to in turn manipulate the running program, (via the ProcessorEnvironment getProgramStack method.) A typical instruction should simply increment the program counter of the current program, but specialized instructions may add sub programs to the stack or not increment the counter (so that they are executed again.)
