Method Details

getBlazeOrderList

List<BlazeOrder> getBlazeOrderList()

Like getOrderList() but returns the subtype BlazeOrder instead.

Returns:

The list of ordering expressions

getOrderList

List<Order> getOrderList()

Return the ordering expressions in order of precedence. Returns empty list if no ordering expressions have been specified. Modifications to the list do not affect the query.

Returns:

the list of ordering expressions

orderBy

BlazeSubquery<T> orderBy(Order... orders)

Specify the ordering expressions that are used to order the query results. Replaces the previous ordering expressions, if any. If no ordering expressions are specified, the previous ordering, if any, is simply removed, and results will be returned in no particular order. The order of the ordering expressions in the list determines the precedence, whereby the first element in the list has highest precedence.

Parameters:

orders - zero or more ordering expressions

Returns:

this for chaining

orderBy

BlazeSubquery<T> orderBy(BlazeOrder... orders)

Like orderBy(Order...) but accepts the subtype BlazeOrder.

Parameters:

orders - zero or more ordering expressions

Returns:

this for chaining

orderBy

BlazeSubquery<T> orderBy(List<BlazeOrder> orderList)

Specify the ordering expressions that are used to order the query results. Replaces the previous ordering expressions, if any. If no ordering expressions are specified, the previous ordering, if any, is simply removed, and results will be returned in no particular order. The order of the ordering expressions in the list determines the precedence, whereby the first element in the list has highest precedence.

Parameters:

orderList - list of zero or more ordering expressions

Returns:

this for chaining

getParameters

Set<ParameterExpression<?>> getParameters()

Returns the parameters defined on this query.

Returns:

The parameters

getContainingQuery

BlazeCommonAbstractCriteria getContainingQuery()

Returns the query (which may be a CriteriaQuery, CriteriaUpdate, CriteriaDelete, or a Subquery) of which this is a subquery.

Returns:

The enclosing query or subquery
