Examples of org.apache.poi.hpsf.ClassID

org.apache.poi.hpsf.ClassID

Represents a class ID (16 bytes). Unlike other little-endian type the {@link ClassID} is not just 16 bytes stored in the wrongorder. Instead, it is a double word (4 bytes) followed by two words (2 bytes each) followed by 8 bytes.
