Methods in org.apache.openjpa.persistence.query that return DomainObject

Modifier and Type	Method and Description
DomainObject	QueryDefinitionImpl.addRoot(Class cls) Root domain object has no parent, no path but a non-null Class.
DomainObject	AbstractDomainObject.addRoot(Class cls) Adding a root adds a root domain to the owning query.
DomainObject	QueryDefinition.addRoot(Class cls) Add a query root corresponding to the given entity, forming a cartesian product with any existing roots.
DomainObject	QueryDefinitionImpl.addSubqueryRoot(PathExpression path)
DomainObject	AbstractDomainObject.addSubqueryRoot(PathExpression path) Adding a query root adds a subquery to the owning query.
DomainObject	QueryDefinition.addSubqueryRoot(PathExpression path) Add a root derived from a domain object of the containing query definition to a query definition used as a subquery.
DomainObject	QueryBuilder.createQueryDefinition(Class root) Create a query definition object with the given root.
DomainObject	QueryBuilderImpl.createQueryDefinition(Class root) Creates a QueryDefinition with given class as domain.
DomainObject	QueryBuilder.createSubqueryDefinition(PathExpression path) Create a query definition object whose root is derived from a domain object of the containing query.
DomainObject	QueryBuilderImpl.createSubqueryDefinition(PathExpression path) Creates a QueryDefinition that can be used a correlated subquery with the given path as domain.
DomainObject	AbstractDomainObject.join(String attr) Derives a path from this path by joining the given field.
DomainObject	DomainObject.join(String attribute) Extend the query domain by joining with a class that can be navigated to or that is embedded in the class corresponding to the domain object on which the method is invoked.
DomainObject	AbstractDomainObject.leftJoin(String attr) Derives a path from this path by outer joining the given field.
