Package org.datanucleus.store.rdbms.sql.expression Description

Series of expressions representing conditions in SQL statements. Each expression represents an object, of a type, and hence has a JavaTypeMapping responsible for any get/set of that object in the SQL statement. Calling of the toSQL() method on an expression generates the SQL that it represents.
