- searchProvidedTypeHandler
  
  public static <D, T> PersistenceTypeHandler<D,T> searchProvidedTypeHandler(Class<D> dataType, Class<T> entityType, Predicate<? super Method> selector) throws ReflectiveOperationException
  
  Searches the methods of the passed entityType for a static method with arbitrary name and visibility, no arguments and PersistenceTypeHandler or a sub type of it as its return type.
  Which method to select is also determined by testing the returned PersistenceTypeHandler instance if it has the correct PersistenceTypeHandler.dataType() for the used persistence context and the correct PersistenceTypeHandler.type() for the given entity class.
  This mechanism is a convenience shortcut alternative to PersistenceFoundation.registerCustomTypeHandler(PersistenceTypeHandler).
  
  Type Parameters:
  
  D -
  
  T -
  
  Parameters:
  
  dataType -
  
  entityType -
  
  Throws:
  
  ReflectiveOperationException
