Class DmcAttributeInfo

java.lang.Object

org.dmd.dmc.DmcAttributeInfo

All Implemented Interfaces:

Comparable<DmcAttributeInfo>

public class DmcAttributeInfo
extends Object
implements Comparable<DmcAttributeInfo>

The DmcAttributeInfo class is a helper class that stores a small amount of information about the individual attributes that comprise a generated Dark Matter object (DMO). This information is used to assist with serialization and deserialization of objects in a generic manner. In some regards, it can be seen as serving a similar purpose to the information provided to the Google Protocol Buffer mechanisms, except that its information is derived from the AttributeDefinition of Dark Matter Schema (DMS) specifications.
