# Term: ActiveMeshObjectSet

A MeshObjectSet that autonomously recalculates its content by subscribing to and evaluating certain events, such as events emitted by MeshObjects.

ActiveMeshObjectSets provide methods that enable listeners to receive events when the content of the ActiveMeshObjectSet changes.

InfoGrid provides several kinds of active sets, including:

- the set of all MeshObjects found at "the other end" of a Relationship Traversal from a given start MeshObject. Example: the set of all Order MeshObjects, given a Customer MeshObject.
- the set of all MeshObjects that can be found by traversing N Relationships from a given start MeshObject.
- the (sub-)set of all MeshObjects that meet a certain criteria, given another ActiveMeshObjectSet as an input.
