Package org.vast.swe.fast

Class DataBlockProcessor

java.lang.Object

org.vast.swe.fast.DataBlockProcessor

All Implemented Interfaces:

DataComponentVisitor

Direct Known Subclasses:

AbstractDataParser, AbstractDataWriter

public abstract class DataBlockProcessor
extends Object
implements DataComponentVisitor

Base class for all data block level processors.
The processor tree is pre-configured so that the processing can occur very fast on many data blocks matching the same components structure.
