Description

The operator count_objcount_objcount_objCountObjCountObj determines for the object parameter ObjectsObjectsObjectsObjectsobjects the number of objects it contains. In this connection it should be noted that object is not the same as connection component (see connectionconnectionconnectionConnectionConnection). For example, the number of objects of a region not consisting of three connected parts is 1.

Parallelization

Parameters

Complexity

Runtime complexity: O(|ObjectsObjectsObjectsObjectsobjects|).

Result

count_objcount_objcount_objCountObjCountObj returns the value 2 (H_MSG_TRUE).
