      • findGetter

        public static java.lang.reflect.Method findGetter​(java.lang.Object object,
                                                  java.lang.String fieldName)
        Returns the getter method associated with the object's field.
        Parameters:
        object - the object
        fieldName - the name of the field
        Returns:
        the getter method
        Throws:
        java.lang.NullPointerException - if object or fieldName is null
        SuperCsvReflectionException - if the getter doesn't exist or is not visible

      • findSetter

        public static java.lang.reflect.Method findSetter​(java.lang.Object object,
                                                  java.lang.String fieldName,
                                                  java.lang.Class<?> argumentType)
        Returns the setter method associated with the object's field.

        This method handles any autoboxing/unboxing of the argument passed to the setter (e.g. if the setter type is a primitive int but the argument passed to the setter is an Integer) by looking for a setter with the same type, and failing that checking for a setter with the corresponding primitive/wrapper type.

        It also allows for an argument type that is a subclass or implementation of the setter type (when the setter type is an Object or interface respectively).

        Parameters:
        object - the object
        fieldName - the name of the field
        argumentType - the type to be passed to the setter
        Returns:
        the setter method
        Throws:
        java.lang.NullPointerException - if object, fieldName or fieldType is null
        SuperCsvReflectionException - if the setter doesn't exist or is not visible
