org.apache.stanbol.enhancer.servicesapi.helper.ContentItemImpl
A generic ContentItem implementation that takes the uri, main content part and the graph used to store the metadata as parameter.
This content item consisting initially of a single blob. Subclasses don't have to care about multi-parts aspects of content item. By inheriting from this class the ability for clients to add additional parts is ensured.
Even through this class does implement the full {@link ContentItem} interfaceit is marked as abstract and has only a protected constructor because it is not intended that users directly instantiate it. The intended usage is to create subclasses that instantiate ContentItmes with specific combinations of {@link Blob} nad {@link MGraph} implementations.
Examples are:
- The {@link InMemoryContentItem} intended for in-memorystorage of ContentItems during the stateless enhancement workflow
- The {@link WebContentItem} that allows to create a ContentItem from an URI.
TODO (rwesten): check if we want this to be an abstract class or if there are reasons to have a general purpose ContentItem implementation
