`jinja2.sandbox.MutableSet`¶

class jinja2.sandbox.MutableSet[source]¶

A mutable set is a finite, iterable container.

This class provides concrete generic implementations of all methods except for __contains__, __iter__, __len__, add(), and discard().

To override the comparisons (presumably for speed, as the semantics are fixed), all you have to do is redefine __le__ and then the other operations will automatically follow suit.

Methods¶

`add`(value)	Add an element.
`clear`()	This is slow (creates N new iterators!) but effective.
`discard`(value)	Remove an element.
`isdisjoint`(other)	Return True if two sets have a null intersection.
`pop`()	Return the popped value.
`remove`(value)	Remove an element.
