True in case of a value with primitive type; undefined if the type is unknown.
True in case of a value with primitive type; undefined if the type is unknown.
True if the value has a reference type; undefined if the type is unknown.
True if the value has a reference type; undefined if the type is unknown.
Returns true
if no type information is available.
Returns true
if no type information is available.
Specifies that no type information is available.
Recall that the computational type of a value always has to be available, but that a
ValuesDomain.typeOfValue(...)
query does not need to take the computational type into account. (Whenever the core framework requires the computational type of a value it uses the respective method.) However, in case that the underlying value may be an array or exception value the reported type must not beTypeUnknown
.
