AttributeHandler - Dealing with Attributes

The attributeHandler class is responsible for managing a single attribute in the a given boObject instance. In an Object Model, each attribute is of given type but in the Java API the attributeHandler class is responsible for dealing with all of them (except collection attributes, for that use the BridgeHandler). This means an attributeHandler class has methods to retrieve and set the value of the attribute with different types (it's up to the developer to know an attribute's type). It's possible, however, to check the attribute model definition for its data type.

In the following sections the most important methods of the API will be presented.
