protected KeyDao()

Method Detail

createStorableInstance

protected KeyEntity createStorableInstance(Key key)

Description copied from class: AbstractDao

Creates the instance of the persistent object (Entity).

Specified by:

createStorableInstance in class AbstractDao<String,KeyEntity,Key,KeyFilter,EmptySortAttribute>

Parameters:

key - transport object to get the data from.

Returns:

a new instance of the persistent object.

doConvert

protected Key doConvert(KeyEntity source)

Description copied from class: AbstractDao

Converts the persistent object to a transport object.

Specified by:

doConvert in class AbstractDao<String,KeyEntity,Key,KeyFilter,EmptySortAttribute>

Parameters:

source - persistent object to convert.

Returns:

a transport object with the same data than source

conform

protected void conform(KeyEntity target,
                       Key source)

Description copied from class: AbstractDao

Synchronizes the transport object and the persistent object state. This method is called from AbstractDao.update(Transportable, DataStoreContext), thus if AbstractDao.update(Transportable, DataStoreContext) is overwritten this method could have an empty implementation.

Specified by:

conform in class AbstractDao<String,KeyEntity,Key,KeyFilter,EmptySortAttribute>

Parameters:

target - object to update.

source - object to take the data from.

getQueryPredicate

protected javax.persistence.criteria.Predicate getQueryPredicate(KeyFilter filter,
                                                                 javax.persistence.criteria.CriteriaBuilder builder,
                                                                 javax.persistence.criteria.Root<KeyEntity> root)

Description copied from class: AbstractBaseDao

Augment the underlying database query with specifics to be included as part of the where clause

Specified by:

getQueryPredicate in class AbstractBaseDao<String,KeyEntity,Key,KeyFilter,EmptySortAttribute>

Parameters:

filter - The input filter from which the criteria is set.

builder - the criteria builder object for augmenting the query object

root - the root object type associated with the query

Returns:

Predicate object to be utilized in the query

getSingularAttribute

protected javax.persistence.metamodel.SingularAttribute<? super KeyEntity,?> getSingularAttribute(EmptySortAttribute sortAttribute)

Description copied from class: AbstractBaseDao

Gets the singular attribute (JPA entity attribute -Column- definition)

Specified by:

getSingularAttribute in class AbstractBaseDao<String,KeyEntity,Key,KeyFilter,EmptySortAttribute>

Parameters:

sortAttribute - sort attribute to map a column to.

Returns:

the singular attribute associated to the sorting attribute.
