Class ByCriteriaStatic

java.lang.Object
  edu.internet2.middleware.grouper.hibernate.ByCriteriaStatic

public class ByCriteriaStatic
extends java.lang.Object

for simple criteria queries, use this instead of inverse of control. this will do proper error handling and descriptive exception handling. This will by default use the transaction modes GrouperTransactionType.READONLY_OR_USE_EXISTING, and GrouperTransactionType.READ_WRITE_OR_USE_EXISTING depending on if a transaction is needed.
