Examples of ProcessorPlan

org.teiid.query.processor.ProcessorPlan

This class represents a processor plan. It is generic in that it abstracts the interface to the plan by the processor, meaning that the actual implementation of the plan or the types of processing done by the plan is not important to the processor.

All the implementations of this interface need to implement {@link #clone}method. The plan is only clonable in the pre or post-processing stage, not during the processing state (things like program state, result sets, etc). It's only safe to clone in between query processings. In other words, it's only safe to call {@link #clone} before the call to {@link #open} or afterthe call to {@link #close}.
