Class AlgorithmExecutionContext

java.lang.Object

org.yamcs.algorithms.AlgorithmExecutionContext

public class AlgorithmExecutionContext
extends Object

Algorithms for command verifiers must execute in parallel in different contexts - meaning that each algorithm will have their own values for inputs referring to command specifics (e.g. command sequence count) That's why we associate to each AlgorithmExecutor (which represents the instantiation of one algorithm) one of these AlgorithmExecutionContext. Currently it stores the historical values for parameters requiring that. Each execution context has a parent that stores the values which are not context specific.
