Attribute (Digipost Digg 0.27 API)

java.lang.Object
- no.digipost.util.Attribute<V>

Type Parameters:

V - The type of the object this attribute is mapping.

All Implemented Interfaces:

Serializable, GetsNamedValue<V>, SetsNamedValue<V>
```
public final class Attribute<V>
extends Object
implements GetsNamedValue<V>, SetsNamedValue<V>, Serializable
```
An Attribute defines a String-based name (or key) and the type of a value which the name maps to. This construct offers pseudo-typesafe handling where objects of arbitrary types are retrieved by name and must be manually casted.
