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 objectfieldName
- the name of the field- Returns:
- the getter method
- Throws:
java.lang.NullPointerException
- if object or fieldName is nullSuperCsvReflectionException
- 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 anInteger
) 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
orinterface
respectively).- Parameters:
object
- the objectfieldName
- the name of the fieldargumentType
- the type to be passed to the setter- Returns:
- the setter method
- Throws:
java.lang.NullPointerException
- if object, fieldName or fieldType is nullSuperCsvReflectionException
- if the setter doesn't exist or is not visible
