Method Details

addConstraints

void addConstraints(javax.persistence.criteria.Predicate... predicates)

Add new Predicates which will be ANDed together with the top-level constraints specified in the WebQuery

Parameters:

predicates - the predicate(s) to add

addConstraints

void addConstraints(List<WQConstraintLine> constraints)

Add new constraints as if they'd been defined at the top level of the WebQuery (N.B. will be ANDed together with all other constraints

Parameters:

constraints -

getProperty

javax.persistence.criteria.Expression<?> getProperty(WQPath path)

Get a property as an expression for use in a constraint; will automatically set up non-fetch joins as needed

Parameters:

path -

Returns:

getOrCreateJoin

JPAJoin getOrCreateJoin(WQPath path)

Get or create non-fetch join(s) to a particular relation path. N.B. should not include a property as part of the path

Parameters:

path -

Returns:

applyFetches

void applyFetches()

Set up fetch joins as specified by the dbfetch/expand/default EAGER fetch annotations
