HWPFDocumentCore (POI API Documentation)

java.lang.Object
- org.apache.poi.POIDocument
- - org.apache.poi.hwpf.HWPFDocumentCore

All Implemented Interfaces:

java.io.Closeable, java.lang.AutoCloseable

Direct Known Subclasses:

HWPFDocument, HWPFOldDocument
```
public abstract class HWPFDocumentCore
extends POIDocument
```
This class holds much of the core of a Word document, but without some of the table structure information. You generally want to work with one of HWPFDocument or HWPFOldDocument

                                throws java.io.IOException
```
    Reads OLE Stream into byte array - if an EncryptionInfo is available, decrypt the bytes starting at encryptionOffset. If encryptionOffset = -1, then do not try to decrypt the bytes
    
    Parameters:
    
    name - the name of the stream
    
    encryptionOffset - the offset from which to start decrypting, use -1 for no decryption
    
    len - length of the bytes to be read, use Integer.MAX_VALUE for all bytes
    
    Returns:
    
    the read bytes
    
    Throws:
    
    java.io.IOException - if the stream can't be found
