newLinkedHashMap

public static <K,V> Map<K,V> newLinkedHashMap()

entitiesEqual

public static boolean entitiesEqual(SessionImplementor session,
                                    String entityName,
                                    Object obj1,
                                    Object obj2)

getIdentifier

public static Object getIdentifier(SessionImplementor session,
                                   String entityName,
                                   Object obj)

getTargetFromProxy

public static Object getTargetFromProxy(SessionFactoryImplementor sessionFactoryImplementor,
                                        HibernateProxy proxy)

getTargetClassIfProxied

public static <T> Class<T> getTargetClassIfProxied(Class<T> clazz)

Type Parameters:

T - Class type.

Parameters:

clazz - Class wrapped with a proxy or not.

Returns:

Returns target class in case it has been wrapped with a proxy. If null reference is passed, method returns null.

objectsEqual

public static boolean objectsEqual(Object obj1,
                                   Object obj2)

iteratorToList

public static <T> List<T> iteratorToList(Iterator<T> iter)

iteratorsContentEqual

public static boolean iteratorsContentEqual(Iterator iter1,
                                            Iterator iter2)

listToIndexElementPairList

public static <T> List<Pair<Integer,T>> listToIndexElementPairList(List<T> list)

Transforms a list of arbitrary elements to a list of index-element pairs.

Parameters:

list - List to transform.

Returns:

A list of pairs: ((0, element_at_index_0), (1, element_at_index_1), ...)

getProperty

public static String getProperty(Properties properties,
                                 String propertyName,
                                 String legacyPropertyName,
                                 String defaultValue)

Parameters:

properties - Properties from which to read.

propertyName - The name of the property.

legacyPropertyName - Legacy name of the property. The value of this property is read if value for propertyName is not set.

defaultValue - Default value returned if a value neither for propertyName or legacyPropertyName is set.

Returns:

The value of the property, legacy proparty or the default value, if neither of the values are not set.

getEntityClass

public static Class getEntityClass(SessionImplementor sessionImplementor,
                                   Session session,
                                   String entityName)

Returns:

Java class mapped to specified entity name.
