Subject [jira] [Commented] (LANG-778) Add UUIDUtils.toByteArray and UUIDUtils.fromByteArray
Date Wed, 23 Nov 2011 17:15:39 GMT

    [ https://issues.apache.org/jira/browse/LANG-778?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13155969#comment-13155969
] 

Sebb commented on LANG-778:
---------------------------

OK, so is there any documentation that we can point to which describes the format of those
16 bytes?

Assuming Oracle and HSQLDB use the same format, then perhaps there is a common standard that
can be referenced.

Maybe this is just a defacto standard.

Either way, we should add the details to the documentation, especially if we want to be compatible
with Oracle/HSQLDB.

> A UUID represents 16 bytes. In some situation (e.g. using DBs that do not have native
support for the type UUID) it is necessary to use directly the bytes. The JDK does not support
the transformation from UUID to bytes and back, therefore I'd like to add UUIDUtils with the
two proposed methods.
