Attributes and properties of objects
An XMS object can have attributes and properties, which are characteristics of the object, that are implemented in different ways.
- Attributes
- An object characteristic that is always present and occupies storage, even if the attribute does not have a value. In this respect, an attribute is similar to a field in a fixed-length data structure. A distinguishing feature of attributes is that each attribute has its own methods for setting and getting its value.
- Properties
- A property of an object is present and occupies storage only after its value is set. A property cannot be deleted or its storage recovered after its value is set. You can change its value. XMS provides a set of generic methods for setting and getting property values.
