Interface PersistentFileContents

All Known Implementing Classes:

BlobPersistentFileContents, ByteArrayPersistentFileContents, DatabaseFileContents, InputStreamFileContents, SystemFileContents

public interface PersistentFileContents

Extends PersistentFile adding the file contents as an InputStream. File contents are kept apart to avoid them from being loaded eagerly. Lazy loading in some JPA containers (e.g. hibernate) required class code post-processing.
