Classes

Class	Description
Criteria	Use `Criteria` to specify the search conditions of a query. At runtime, DomainObjects converts a `Criteria` instance to the `WHERE` clause of a SQL statement. Each instance of a `Criteria` in a query generates a parenthesized set of constraints in a `WHERE` clause.
DeleteByCriteria	Use `DeleteByCriteria` to execute 'batch' deletes to your domain objects directly to the database. At runtime DomainObjects translates a `DeleteByCriteria` instance into a SQL `DELETE` statement.
InsertByQuery<InsertIntoClass,SelectFromClass>	Use `InsertByQuery` to 'batch' insert your domain objects directly to the database via a select subquery. At runtime DomainObjects translates an `InsertByQuery` instance into a SQL `INSERT INTO...SELECT` statement.
PersistenceFacade	Use `PersistenceFacade` to transactionally persist or delete objects that have been created, modified, or deleted outside the context of a transaction.
Query	`Query` is an abstract base class for queries handled by DomainObjects. This class is not intended for subclassing outside of the DomainObjects framework. Use `Query<ClassToFind>` to create your queries.
Query<ClassToFind>	Use `Query<ClassToFind>` to define a query in terms of your object model. At runtime DomainObjects translates a `Query<ClassToFind>` instance into a SQL `SELECT` statement.
ScalarQuery	ScalarQuery is an abstract base class for queries handled by DomainObjects. This class is not intended for subclassing outside of the DomainObjects framework. Use ScalarQuery`1 to create your queries.
ScalarQuery<SelectFromClass>	A query that returns a single scalar value (one column, one row).
TableExpressionQuery
TableExpressionQuery<ClassToFind>
UpdateByCriteria	Use `UpdateByCriteria` to execute 'batch' updates to your domain objects directly to the database. At runtime DomainObjects translates an `UpdateByCriteria` instance into a SQL `UPDATE` statement.
