Interface Resource

All Known Subinterfaces:
  BinaryResource, XMLResource

All Known Implementing Classes:
  LocalBinaryResource, LocalXMLResource, RemoteBinaryResource, RemoteXMLResource

public interface Resource

`Resource` is a container for data stored within the database. Raw resources are not particulary useful. It is necessary to have a resource implementation that provides handling for a specific content type before anything useful can be done.

Method Summary
`java.lang.Object` | `getContent()` Retrieves the content from the resource.
`java.lang.String` | `getId()` Returns the unique id for this `Resource` or null if the `Resource` is anonymous.
`Collection` | `getParentCollection()` Returns the `Collection` instance that this resource is associated with.
`java.lang.String` | `getResourceType()` Returns the resource type for this Resource.
`void` | `setContent(java.lang.Object value)` Sets the content for this resource.
