Remarks
Provides an java.io.InputStream-like interface for accessing an entity's data during a restore operation. Used by BackupHelper classes within the BackupAgentHelper mechanism.
When BackupHelper#restoreEntity(BackupDataInputStream) BackupHelper.restoreEntity() is called, the current entity's header has already been read from the underlying BackupDataInput. The entity's key string and total data size are available through this class's #getKey() and #size() methods, respectively. <p class="note"> <strong>Note:</strong> The caller should take care not to seek or close the underlying data source, nor read more than #size() bytes from the stream.
