      Description

      During the development of https://github.com/apache/openjpa/pull/69/files Romain Manni-Bucau suggested to keep track of the fact that a DBIdentifier contains a name that has been already delimited, this way operations like "removeDelimiters" can be no-op.

       

      This flag can be set during the creation of a DBIdentifier by the DBDictionary, basically when the DBIdentifier forces delimitAll=true
