Class ContainerProcessingContext

java.lang.Object

org.yamcs.mdb.ContainerProcessingContext

public class ContainerProcessingContext
extends Object

Keeps track of where we are when processing a packet.

It embeds the ContainerProcessingResult which is an extension of ProcessingContext. This accumulates the results of the processing (i.e. the parameters extracted from the packet)

We create an object of this class for all containers processed in hierarchy (i.e. inheritance). Each time a sub-container is encountered, a new object of this class is created (because the offset in the binary starts from 0 in the sub-container), keeping the reference to the same ContainerProcessingResult/ProcessingContext.
