Detailed Description

This is a utility class with only static functions for dealing with namespaces that encodes all the "magic" behaviors of them based on index.

The textual names of the namespaces are handled by Language.php.

These are synonyms for the names given in the language file Users and translators should not change them

Member Function Documentation

static MWNamespace::canTalk (   $index)
static

Does this namespace ever have a talk namespace?

Deprecated:
since 1.30, use hasTalkNamespace() instead.
Parameters
int$indexNamespace index
Returns
bool True if this namespace either is or has a corresponding talk namespace.

Definition at line 288 of file MWNamespace.php.

Referenced by ChangesFeed\buildItems(), and MWNamespaceTest\testCanTalk().

static MWNamespace::equals (   $ns1,
  $ns2 
)
static

Returns whether the specified namespaces are the same namespace.

Note
It's possible that in the future we may start using something other than just namespace indexes. Under that circumstance making use of this function rather than directly doing comparison will make sure that code will not potentially break.
Parameters
int$ns1The first namespace index
int$ns2The second namespace index
Returns
bool

1.19

Member Data Documentation

MWNamespace::$alwaysCapitalizedNamespaces = [ NS_SPECIAL, NS_USER, NS_MEDIAWIKI ]
staticprivate

These namespaces should always be first-letter capitalized, now and forevermore.

Historically, they could've probably been lowercased too, but some things are just too ingrained now. :)
