Class DefaultMappedQuery<T,D>

java.lang.Object

io.ebeaninternal.server.querydefn.DefaultMappedQuery<T,D>

All Implemented Interfaces:

io.ebean.MappedQuery<D>

public final class DefaultMappedQuery<T,D>
extends Object
implements io.ebean.MappedQuery<D>

Default implementation of MappedQuery backing query.mapTo(dtoType).

Resolves the generated DtoMapper for the query's (entity, dto) pair, applies its DtoMapper.fetchGroup() (derived from the target DTO's declared shape) - unless the caller has already specified their own select()/fetch() spec, in which case that manual spec is left untouched - and forces setUnmodifiable(true) on the underlying query before it is executed, then maps the resulting entity graph into the target DTO graph.

Constructor	Description
DefaultMappedQuery(SpiEbeanServer server, SpiQuery<T> query, Class<D> dtoType)
DefaultMappedQuery(SpiEbeanServer server, SpiQuery<T> query, Class<D> dtoType, io.ebean.DtoMapper<T,D> mapper)	Use an already-resolved mapper instance directly - e.g. a named variant accessor on a generated mapper, such as query.mapTo(User.class, userMapper.noFleets()) - bypassing server.dtoMapper(...) lookup entirely.
