enum dds::core::xtypes::ExtensibilityKind_def::type

The underlying enum type

Enumerator:

FINAL	Specifies that a type has FINAL extensibility. A type may be final, indicating that the range of its possible values is strictly defined. In particular, it is not possible to add elements to members of collection or aggregated types while maintaining type assignability. The following types are always final: dds::core::xtypes::TypeKind_def::ARRAY_TYPE All primitive types
EXTENSIBLE	Specifies that a type has EXTENSIBLE extensibility. A type may be extensible, indicating that two types, where one contains all of the elements/members of the other plus additional elements/members appended to the end, may remain assignable.
MUTABLE	Specifies that a type has MUTABLE extensibility. A type may be mutable, indicating that two types may differ from one another in the additional, removal, and/or transposition of elements/members while remaining assignable. The following types are always mutable: dds::core::xtypes::TypeKind_def::SEQUENCE_TYPE dds::core::xtypes::TypeKind_def::STRING_TYPE dds::core::xtypes::TypeKind_def::WSTRING_TYPE
