Class NumberBufferWrapper

java.lang.Object

de.esprit.common.util.DumpableObject

de.esprit.common.log.SimpleLogSupportAdapter

de.esprit.appsuite.nio.binary.ByteBufferWrapper

de.esprit.appsuite.nio.binary.NumberBufferWrapper

All Implemented Interfaces:

BinaryDataStructure, SimpleLogSupport, Dumpable, Resettable

Direct Known Subclasses:

DoubleBufferWrapper, FloatBufferWrapper, IntBufferWrapper, LongBufferWrapper, ShortBufferWrapper

public abstract class NumberBufferWrapper
extends ByteBufferWrapper

This is the super class for all number based buffer wrappers. It allows for getting the start-position of an indexed value which is useful in order to read single values of huge arrays rather than loading the whole array.
