Constructor Detail

QueryBuilder

public QueryBuilder(String entityName,
                    String alias,
                    SessionFactoryImplementor sessionFactory)

Parameters:

entityName - Main entity which should be selected.

alias - Alias of the entity

sessionFactory - Session factory

Method Detail

deepCopy

public QueryBuilder deepCopy()

getAlias

public String getAlias()

Returns:

the main alias of this query builder

addFrom

public void addFrom(String entityName,
                    String alias,
                    boolean select)

Add an entity from which to select.

Parameters:

entityName - Name of the entity from which to select.

alias - Alias of the entity. Should be different than all other aliases.

select - whether the entity should be selected

addJoin

public Parameters addJoin(JoinType joinType,
                          String entityName,
                          String alias,
                          boolean select)

generateAlias

public String generateAlias()

newSubQueryBuilder

public QueryBuilder newSubQueryBuilder(String entityName,
                                       String alias)

Parameters:

entityName - Entity name, which will be the main entity for the sub-query.

alias - Alias of the entity, which can later be used in parameters.

Returns:

A sub-query builder for the given entity, with the given alias. The sub-query can be later used as a value of a parameter.
