All Implemented Interfaces:
IAttrTable
public class AttrTable
extends java.lang.Object
implements IAttrTable

A base class to access an attribute table. . Attribute table always store attributes in their native format, eg. color as Color object. Clients accessing the attribute table should knows the attribute type it is accessing. . For convenient, attributes can always be get/store through a String representation. attrString() always return the String representation of the attribute object and createAttr() method converts the String to the appropriate object type by consulting the AttrRegistry.
