<clause number="10.8.1" title="Fully qualified names">
|
||
|
|
<paragraph>Every namespace and type has a fully qualified name, which uniquely identifies the namespace or type amongst all others. The fully qualified name of a namespace or type N is determined as follows: <list><list_item> If N is a member of the global namespace, its fully qualified name is N. </list_item><list_item> Otherwise, its fully qualified name is S.N, where S is the fully qualified name of the namespace or type in which N is declared. </list_item></list></paragraph>
|
||
|
|
<paragraph>In other words, the fully qualified name of N is the complete hierarchical path of identifiers that lead to N, starting from the global namespace. Because every member of a namespace or type must have a unique name, it follows that the fully qualified name of a namespace or type is always unique. </paragraph>
