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

public class SingleCollectionLiteral
extends SingleCollectionExpression
implements 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".
