Method Detail

create

public static <T extends Persistable<PK>,PK extends java.io.Serializable> ExtendedGenericDao<T,PK> create(javax.persistence.EntityManager entityManager,
                                                                                                          java.lang.Class<T> domainClass)

Factory method to create GenericEclipseLinkJpaDao instances.

Type Parameters:

T - the type of the entity to handle

PK - the type of the entity's identifier

Parameters:

entityManager - the EntityManager backing the DAO

domainClass - the domain class to handle

Returns:

readByExample

public java.util.List<T> readByExample(java.util.Collection<T> examples)

Description copied from interface: ExtendedGenericDao

Returns all entites matching the given criteria sorted by the given sort options.

Returns:

all entites matching the given criteria sorted by the given sort options
