Errors/Exceptions
-----------------
.. include:: /includes/extracts/error-invalidargumentexception.rst
Behavior
--------
If you construct a Collection explicitly, the Collection inherits any options
from the :php:`MongoDB\\Driver\\Manager <class.mongodb-driver-manager>` object.
If you select the Collection from a :phpclass:`Client <MongoDB\\Client>` or
:phpclass:`Database <MongoDB\\Database>` object, the Collection inherits its
options from that object.
.. todo: add an example
