Each EnumValue has a base value and a display value. The type of the base value can be either String or Integer. Every EnumValue has a display value.
If the value of an Enumeration type object attribute is
null
, when that attribute is accessed an EnumValue is returned
that has a base value of null
, rather than null
itself. This means that empty(object.attribute)
would be
false
, and empty(object.attribute.value)
would be
true
