public abstract class AbstractIntCollection
extends AbstractPrimitiveCollectable<Integer>
implements IntCollection

Abstract base class for collections of primitive int elements.

This class implements Collection allowing seamless integration with other APIs.

The iterator and size must be implemented by subclases. To make the subclass modifiable, the add(int) and iterator remove() methods must also be implemented. Subclasses may override other methods to increase efficiency.

Checks if this collection contains all of the values in the specified array. If the specified array is empty, true is returned.

This implementation uses contains(int).

Parameters:

values - the values to search for, null treated as empty array

Returns:

Parameters:

values - the values to search for, null treated as empty array

Returns:

true if at least one of the values is found
