Class Stream

java.lang.Object
  org.apache.poi.hdgf.streams.Stream

Direct Known Subclasses:

ChunkStream, PointerContainingStream, StringsStream, UnknownStream

public abstract class Stream
extends java.lang.Object

Base of all Streams within a HDGF document. Streams are what hold the data (the metadata of a stream is held in the pointer that points to the stream). A stream may be stored compressed or un-compressed on the disk, but that doesn't appear to change their use.
