All Known Implementing Classes:

FileStorageObjectData, InMemoryStorageObjectData, StorageObjectDataBase

public interface StorageObjectData

Interface for system-specific objects that hold or enable access to the data for a storage object, e.g., a File object. The data is always managed as bytes, not characters.

Method Summary

void	close() Closes any open output streams.
byte[]	getBytes() Gets all the bytes of the storage object.
java.io.InputStream	getInputStream() Gets an input stream from which the storage object data bytes can be read.
java.io.OutputStream	getOutputStream() Returns an exclusive output stream to which new data can be written.
StorageObject	getStorageObject()
boolean	isOpen() Returns true if the data object is open for writing.
long	size() Returns the number of bytes in the storage object.
