public static Method findSetter(Class<?> type,
                                String fieldName)

Returns the setter method for a field name in a specified class.

Parameters:

type - the class

fieldName - field name

Returns:

setter method for a field or null

findSetter

public static Method findSetter(Class<?> type,
                                String fieldName,
                                Set<Class<?>> mappableTypes)

Returns the setter method for a field name in a specified class that uses a parameter of a type in a set.

Parameters:
