edu.harvard.hul.ois.jhove.module.BytestreamModule
- All Implemented Interfaces: 
- Module
- public final class BytestreamModule 
- extends ModuleBase
Module for analysis of content as a byte stream.
  This is the module of last resort, accepting any content as
  valid and well-formed.

BytestreamModule
public BytestreamModule()
- Creates a BytestreamModule.
 
parse
public final int parse(java.io.InputStream stream,
                       RepInfo info,
                       int parseIndex)
                throws java.io.IOException
- Parse the content of a stream digital object and store the
   results in RepInfo.
   Any arbitrary bytestream is considered well-formed.
 
- 
- Specified by:
- parsein interface- Module
- Overrides:
- parsein class- ModuleBase
 
- 
- Parameters:
- stream- An InputStream, positioned at its beginning,
                    which is generated from the object to be parsed.
                    If multiple calls to- parseare made 
                    on the basis of a nonzero value being returned,
                    a new InputStream must be provided each time.
- info- A fresh (on the first call) RepInfo object 
                    which will be modified
                    to reflect the results of the parsing
                    If multiple calls to- parseare made 
                    on the basis of a nonzero value being returned, 
                    the same RepInfo object should be passed with each
                    call.
- parseIndex- Must be 0 in first call to- parse.  If- parsereturns a nonzero value, it must be
                    called again with- parseIndexequal to that return value.
- Throws:
- java.io.IOException
 
checkSignatures
public void checkSignatures(java.io.File file,
                            java.io.InputStream stream,
                            RepInfo info)
                     throws java.io.IOException
- Check signature.  Bytestreams have no signatures, but since any
 byte stream is considered a valid Bytestream, return immediately
 doing nothing.  The RepInfo._consistent flag will remain true.
 
- 
- Specified by:
- checkSignaturesin interface- Module
- Overrides:
- checkSignaturesin class- ModuleBase
 
- 
- Parameters:
- file- A File object for the object being parsed
- stream- An InputStream, positioned at its beginning,
                    which is generated from the object to be parsed
- info- A fresh RepInfo object which will be modified
                    to reflect the results of the test
- Throws:
- java.io.IOException
