Modifier and Type	Method	Description
com.querydsl.core.types.Predicate	createExistsPredicate(SqaleQueryContext<?,Q,R> context)	This creates the predicate representing the EXISTS filter.
SqaleUpdateContext<?,?,?>	resolve(SqaleUpdateContext<?,Q,R> context, ItemPath itemPath)	Resolves current query context to a new context (mapping is always part of context).
ItemRelationResolver.ResolutionResult<Q,R>	resolve(SqlQueryContext<?,Q,R> context)	Should not be called, the count must be treated before this happens.

Method Detail

resolve

public ItemRelationResolver.ResolutionResult<Q,R> resolve(SqlQueryContext<?,Q,R> context)

Should not be called, the count must be treated before this happens.

Specified by:

resolve in interface ItemRelationResolver<Q extends FlexibleRelationalPathBase<R>,R,Q extends FlexibleRelationalPathBase<R>,R>

createExistsPredicate

public com.querydsl.core.types.Predicate createExistsPredicate(SqaleQueryContext<?,Q,R> context)

This creates the predicate representing the EXISTS filter.

Description copied from interface: SqaleItemRelationResolver

Resolves current query context to a new context (mapping is always part of context). The information about the resolved item is captured in the instance resolver already in a manner that is specific for various types of resolution (JOIN or nested mapping). Optional ItemPath is provided for cases when container ID is necessary. Return value `null` indicates that the modification using the resolver should be ignored by the repository.

Specified by:

resolve in interface SqaleItemRelationResolver<Q extends FlexibleRelationalPathBase<R>,R,Q extends FlexibleRelationalPathBase<R>,R>
