public final class CircularIntArray
extends Object

java.lang.Object
↳	android.support.v4.util.CircularIntArray

CircularIntArray 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.

Summary

Public constructors
`CircularIntArray()` Creates a circular array with default capacity.
`CircularIntArray(int minCapacity)` Creates a circular array with capacity for at least `minCapacity` elements.

Public methods
`void`	`addFirst(int e)` Add an integer in front of the CircularIntArray.
`void`	`addLast(int e)` Add an integer at end of the CircularIntArray.
`void`	`clear()` Remove all integers from the CircularIntArray.
`int`	`get(int n)` Get nth (0 <= n <= size()-1) integer of the CircularIntArray.
`int`	`getFirst()` Get first integer of the CircularIntArray.
`int`	`getLast()` Get last integer of the CircularIntArray.
`boolean`	`isEmpty()` Return true if size() is 0.
`int`	`popFirst()` Remove first integer from front of the CircularIntArray and return it.
`int`	`popLast()` Remove last integer from end of the CircularIntArray and return it.
`void`	`removeFromEnd(int numOfElements)` Remove multiple elements from end of the CircularIntArray, ignore when numOfElements is less than or equals to 0.
`void`	`removeFromStart(int numOfElements)` Remove multiple integers from front of the CircularIntArray, ignore when numOfElements is less than or equals to 0.
`int`	`size()` Get number of integers in the CircularIntArray.
