Class BaseBlob

java.lang.Object

hu.elte.animaltracker.model.tracking.blobs.BaseBlob

All Implemented Interfaces:

java.io.Serializable

Direct Known Subclasses:

ByteBlob, ColorBlob, FloatBlob, ShortBlob

public class BaseBlob
extends java.lang.Object
implements java.io.Serializable

This is a basic blob class which contains several general functions and manages the base of serialization. It has four derived classes (ByteBlob, ShortBlob, FloatBlob, ColorBlob) in accordance with pixel types.
