The DescendantControl object extends the HierarchyControl object.

It is used in the input Root object of the get() API to request descendants of the entity. If the DescendantControl object is added to the Root object in a get() API call, this means the descendants of the entities under the Root object will be returned in the returning Root object.

Besides indicating whether or not to return descendants, DescendantControl can also be used for specifying the properties to be returned for descendants as well as the level of descendants to be returned.

  • level
    • 0: return all descendants
    • 1: return only the children
    • greater than 1: return the specified number of descendants. For example, a level set to 2 will return both the children and the granchildren.

Since DescendantControl is also extended from SearchControl, it is possible to specify other search properties like countLimit, and timeLimit in DescendantControl to only return the descendants which satisfies the search criteria. For example, adding the property expression with value: @xsi:type='Person' to only return the descendants which are of the Person entity type.
