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.

  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.
