public class FindByPersistentMethod
extends AbstractClausedStaticPersistentMethod

The "findBy*" static persistent method. This method allows querying for instances of grails domain classes based on their properties. This method returns the first result of the query eg. Account.findByHolder("Joe Blogs"); // Where class "Account" has a property called "holder" Account.findByHolderAndBranch("Joe Blogs", "London" ); // Where class "Account" has a properties called "holder" and "branch"
