org.yamcs.algorithms.AlgorithmExecutionContext

public class AlgorithmExecutionContext
extends Object

A context is a collection of active algorithms. Each algorithm has only one instance active in a given context.

There is normally a global context in a processor and a few contexts related to the command verifiers.

The process(long, ProcessingData) method will trigger calling all the active algorithms from this context in order.

Method Details

process

public void process(long acqTime,
 ProcessingData data)

Update the input data and run the affected algorithms

Add the result of the algorithms to the processing data

getName

public String getName()

containsAlgorithm

addAlgorithm

public void addAlgorithm(ActiveAlgorithm activeAlgorithm)

removeAlgorithm

public ActiveAlgorithm removeAlgorithm(String algoFqn)

remove the active algorithm with the given identifier.

The algorithm will not be called in subsequent calls to process(long, ProcessingData)

Parameters:

algoFqn -

Returns:

the active algorithm removed or null if there was no active algorithm
