temporaryLoader()

temporaryLoader

(

$class

)

This temporary autoloader allows loading classes with their old-style names (SimpleSAML_Path_Something) even if they have been migrated to namespaces, by registering an alias for the new class.

If the class has not yet been migrated, the autoloader will then try to load it.

Parameters

string

$class

The full name of the class using underscores to separate the elements of the path, and starting with 'SimpleSAML_'.

Deprecated:

This function will be removed in SSP 2.0.
