Class Description


This class has been introduced to create instances of EOSQLExpressions. Very little of the API is new. Rather, most of it was moved EOSQLExpressionFactory from EOSQLExpression. The API is essentially the same except that in 4.5, the methods were static methods. In 5.0 the methods on EOSQLExpressionFactory are instance methods.
