    public class FindByBooleanPropertyPersistentMethod

extends FindByPersistentMethod

The "find<booleanProperty>By*" static persistent method. This method allows querying for instances of grails domain classes based on a boolean property and any other arbitrary properties. This method returns the first result of the query. eg. Account.findActiveByHolder("Joe Blogs"); // Where class "Account" has a properties called "active" and "holder" Account.findActiveByHolderAndBranch("Joe Blogs", "London" ); // Where class "Account" has a properties called "active', "holder" and "branch" In both of those queries, the query will only select Account objects where active=true.
