com.evolveum.midpoint.repo.sqale.mapping.CountMappingResolver<Q,R>

Type Parameters:: Q - query type of entity where the mapping is nested and declared; R - row type of CountMappingResolver

All Implemented Interfaces:: SqaleItemRelationResolver<Q,R,Q,R>, ItemRelationResolver<Q,R,Q,R>

public class CountMappingResolver<Q extends FlexibleRelationalPathBase<R>,R> extends Object implements SqaleItemRelationResolver<Q,R,Q,R>

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, boolean parent)

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

- resolve
  
  public SqaleUpdateContext<?,?,?> resolve(SqaleUpdateContext<?,Q,R> context, ItemPath itemPath)
  
  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.
