Examples of org.apache.abdera.model.Base

org.apache.abdera.model.Base
The Base interface provides the basis for the Feed Object Model API and defines the operations common to both the Element and Document APIs. Classes implementing Base MUST NOT be assumed to be thread safe. Developers wishing to allow multiple threads to perform concurrent modifications to a Base MUST provide their own synchronization.
