| <p><code><a href="/reference/androidx/collection/CircularIntArray.html">CircularIntArray</a></code> is a circular integer array data structure that provides O(1) random read, O(1) prepend and O(1) append. The CircularIntArray automatically grows its capacity when number of added integers is over its capacity.</p> |
