Class SingleCollectionLiteral
java.lang.Object
org.datanucleus.store.rdbms.sql.expression.SQLExpression
org.datanucleus.store.rdbms.sql.expression.DelegatedExpression
org.datanucleus.store.rdbms.sql.expression.SingleCollectionExpression
org.datanucleus.store.rdbms.sql.expression.SingleCollectionLiteral
- All Implemented Interfaces:
SQLLiteral
Cover-all literal to represent "single collection" mapped types.
Note that we should split this up if we ever want to have methods on particular types.
For example we could have OptionalExpression and provide methods "isPresent" and "get".
