org.apache.cayenne.exp.parser.AggregateConditionNode
- All Implemented Interfaces:
Serializable,Node,XMLSerializable
public abstract class AggregateConditionNode extends SimpleNode
Superclass of aggregated conditional nodes such as NOT, AND, OR. Performs
extra checks on parent and child expressions to validate conditions that are
not addressed in the Cayenne expressions grammar.
