Constructor & Destructor Documentation

__construct()

ilObjStudyProgramme::__construct	(		$a_id = 0,

	)

ATTENTION: After using the constructor the object won't be in the cache.

This could lead to unexpected behaviour when using the tree navigation.

Parameters

int	$a_id
bool	$a_call_by_reference
