Method Detail

createPeer

public static <T extends RawEntity<K>,K> T createPeer(EntityManager manager,
                                                      Class<T> type,
                                                      K key)

convertSimpleClassName

public static String convertSimpleClassName(String name)

convertDowncaseName

public static String convertDowncaseName(String name)

interfaceInheritsFrom

public static boolean interfaceInheritsFrom(Class<?> type,
                                            Class<?> superType)

typeInstanceOf

public static boolean typeInstanceOf(Class<?> type,
                                     Class<?> otherType)

getMappingFields

public static String[] getMappingFields(FieldNameConverter converter,
                                        Class<? extends RawEntity<?>> from,
                                        Class<? extends RawEntity<?>> to)

getPolymorphicFieldNames

public static String[] getPolymorphicFieldNames(FieldNameConverter converter,
                                                Class<? extends RawEntity<?>> from,
                                                Class<? extends RawEntity<?>> to)

getAnnotationDelegate

public static AnnotationDelegate getAnnotationDelegate(FieldNameConverter converter,
                                                       Method method)

Note: this method leads to the creation and quick discard of large numbers of AnnotationDelegate objects. Need to do some research to determine whether or not this is actually a problem.

findCounterpart

                                     Method method)

Finds the corresponding method in an accessor/mutator pair based on the given method (or null if no corresponding method).

Parameters:

converter - TODO
