Method Detail
-
toBeanAttributes
public static org.refcodes.struct.Attribute[] toBeanAttributes(Object anObject)
This method uses reflection on order to analyze a given object. The java beans attributes and their values are retrieved and returned in an array of name-to-value pairs.- Parameters:
anObject
- The object to be analyzed.- Returns:
- An array of objects containing the java beans name-to-value pairs.
-
setAttribute
public static void setAttribute(Object anObject, String anAttributeName, Object anAttributeValue) throws NoSuchMethodException
This method sets a java beans attribute for the given object. The corresponding java beans method must begin with a 'set', the following letter must be in upper case and it must only take one argument being of the same (or super-) type as the attribute's type.- Parameters:
anObject
- The object which's java beans method is to be called.anAttributeName
- The attribute name of the java beans method.anAttributeValue
- The value of the attribute to be set.- Throws:
NoSuchMethodException
- Description of the Exception
-
setAttribute
public static void setAttribute(Object anObject, org.refcodes.struct.Attribute anAttributeValueStruct) throws NoSuchMethodException
This method sets a java beans attribute for the given object.- Parameters:
anObject
- The object which's attribute is to be set.anAttributeValueStruct
- The name-to-value struct for the attrubute to be set.- Throws:
NoSuchMethodException
- Description of the Exception
-
hasSetterAttribute
public static boolean hasSetterAttribute(Object anObject, String anAttributeName, Class<?> anAttributeType)
This method tests whether the given java beans setter attribute is found for the given object.- Parameters:
anObject
- The object which is to be tested.anAttributeName
- The attribute name.anAttributeType
- The expected (sub-) type of the attribute- Returns:
- True if the object has a method with the given java beans name which can be called with an argument of the given type.
-
hasGetterAttribute
public static boolean hasGetterAttribute(Object anObject, String anAttributeName, Class<?> aReturnType)
This method tests whether the given java beans getter attribute is found for the given object.- Parameters:
anObject
- The object which is to be tested.anAttributeName
- The attribute name.aReturnType
- The expected (sub-) type of the return value- Returns:
- True if the object has a method with the given java beans name which returns the given (super-) type.
