Method Detail

findGetter

public static Method findGetter(Object object,
                                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:

NullPointerException - if object or fieldName is null

SuperCsvReflectionException - if the getter doesn't exist or is not visible

findSetter

public static Method findSetter(Object object,
                                String fieldName,
                                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:

NullPointerException - if object, fieldName or fieldType is null

SuperCsvReflectionException - if the setter doesn't exist or is not visible
