Unique ID for org.apache.jackrabbit.value.BinaryValue
-----------------------------------------------------

                 Key: JCR-1892
                 URL: https://issues.apache.org/jira/browse/JCR-1892
             Project: Jackrabbit
          Issue Type: New Feature
          Components: jackrabbit-jcr-commons
            Reporter: Thomas Mueller

BinaryValue should have a method get the unique identifier (if one is 
available). That way an application may not have to read the stream if that 
value is already processed.

When the DataStore is used, a unique identifier is available, so probably this 
feature is quite simple to implement.

(but please don't reply to this thread from now on - instead add comments to 
this issue).

Another feature is getFileName() to get the file name if it is stored in the 
file system. This method may need a security mechanism, for example 
getFileName(Session s) so that the system can check it. In any case the file 
should not be modified, but maybe knowing the file name is already too 
dangerous in some cases.
