Direct Known Subclasses:

ContainerAdapter, ItemAdapter, RepositoryAdapter

public abstract class AbstractAdapter
extends Object

This is the abstract adapter containing all the common elements between the three types of adapters: item, container, and repository. Each adapter translate a given type of DSpace object into a METS document for rendering into the DRI document. This class provides the chasses for those unique parts of the document to be build upon, there are seven rendering methods that may be overriden for each section of the METS document.
