Examples of org.apache.derby.authentication.DatabasePrincipal

org.apache.derby.authentication.DatabasePrincipal
This class represents Derby's notion of a principal, a concept of user identity with controlled access to Derby-specific privileges. An authenticated user may have other identities which make sense in other code domains. A principal represents an identity characterized by a user name. The wildcard user name "*" can be used to declare a policy grant to "all users". In future, database-scoped identities will be supported by appending the user name with the distinguished character "@" followed by a database name or the wildcard "*" meaning all databases. Note that the special characters "@" and "*" may be part of the user or database names if escaped by a "\" character; the escaping "\" character itself may be included in a name if doubled.
