Class AbstractPartTreeBlazePersistenceQuery

java.lang.Object
org.springframework.data.jpa.repository.query.AbstractJpaQuery
com.blazebit.persistence.spring.data.base.query.AbstractPartTreeBlazePersistenceQuery
All Implemented Interfaces:
org.springframework.data.repository.query.RepositoryQuery
public abstract class AbstractPartTreeBlazePersistenceQuery extends org.springframework.data.jpa.repository.query.AbstractJpaQuery
Implementation is similar to PartTreeJpaQuery but was modified to work with entity views. About sorting The implementation of both AbstractPartTreeBlazePersistenceQuery and AbstractEntityViewAwareRepository aims to support mixed sorting, i.e. sorting by entity view attributes and entity attributes at the same time. To make this work we abstain from using the attribute sorter API of EntityViewSetting because it would not allow us to add the entity attribute sorts. Instead, we add both entity view attribute and entity attribute sorters uniformly via the core order API of OrderByBuilder *after* the entity view settings have been applied: - For entity view attribute sorts we resolve deterministic aliases from the order property that correspond to the select item aliases - For entity attribute sorts we just use the order property as is Sorters are retrieved from 4 sources. The order these sources are applied to the final query is as follows: 1. method name sorters e.g. findAllByOrderByNameAsc() 2./3. Pageable or Sort method parameter 4. EntityViewSettingProcessor method parameter that adds attribute sorters to the entity view settings
