Package org.yamcs.algorithms

Class ScriptAlgorithmExecutor

java.lang.Object

org.yamcs.algorithms.AbstractAlgorithmExecutor

org.yamcs.algorithms.ScriptAlgorithmExecutor

All Implemented Interfaces:

AlgorithmExecutor

public class ScriptAlgorithmExecutor
extends AbstractAlgorithmExecutor

Represents the execution context of one algorithm. An AlgorithmExecutor is reused upon each update of one or more of its InputParameters.

This class will create and compile on-the-fly ValueBinding implementations for every unique combination of raw and eng types.
