public Neo4jPropertyHelper(org.hibernate.engine.spi.SessionFactoryImplementor sessionFactory,
                           org.hibernate.hql.ast.spi.EntityNamesResolver entityNames,
                           Neo4jAliasResolver aliasResolver)

Method Detail

convertToBackendType

public Object convertToBackendType(String entityType,
                                   List<String> propertyPath,
                                   Object value)

Specified by:

convertToBackendType in interface org.hibernate.hql.ast.spi.PropertyHelper

Overrides:

convertToBackendType in class ParserPropertyHelper

getPropertyIdentifier

public PropertyIdentifier getPropertyIdentifier(String entityType,
                                                List<String> propertyPath,
                                                int requiredDepth)

Returns the PropertyIdentifier for the given property path. In passing, it creates all the necessary aliases for embedded/associations.

Parameters:

entityType - the type of the entity

propertyPath - the path to the property without aliases

requiredDepth - it defines until where the aliases will be considered as required aliases (see Neo4jAliasResolver for more information)

Returns:

the PropertyIdentifier

getColumnName

public String getColumnName(String entityType,
                            List<String> propertyPathWithoutAlias)

getColumnName

public String getColumnName(Class<?> entityType,
                            List<String> propertyName)

isIdProperty

public boolean isIdProperty(String entityType,
                            List<String> propertyPath)

isIdProperty

public boolean isIdProperty(OgmEntityPersister persister,
                            List<String> namesWithoutAlias)

Check if the property is part of the identifier of the entity.

Parameters:

persister - the OgmEntityPersister of the entity with the property

namesWithoutAlias - the path to the property with all the aliases resolved

Returns:

true if the property is part of the id, false otherwise.
