                        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)

arraysEqual

public static boolean arraysEqual(Object[] array1,
                  Object[] array2)

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.

mapToArray

public static Object[] mapToArray(Map<String,Object> data,
                  String[] keys)

Converts map's value set to an array. keys parameter specifies requested elements and their order.

Parameters:

data - Source map.

keys - Array of keys that represent requested map values.

Returns:

Array of values stored in the map under specified keys. If map does not contain requested key, null is inserted.

getProperty

public static XProperty getProperty(XClass clazz,
                    String propertyName)

Parameters:

clazz - Source class.

propertyName - Property name.

Returns:

Property object or null if none with expected name has been found.

getProperty

public static XProperty getProperty(XClass clazz,
                    String propertyName,
                    String accessType)

Parameters:

clazz - Source class.

propertyName - Property name.

accessType - Expected access type. Legal values are field and property.

Returns:

Property object or null if none with expected name and access type has been found.
