abstract public class: AbstractIntCollection [javadoc |
source]
java.lang.Object
org.apache.commons.collections.primitives.AbstractIntCollection
All Implemented Interfaces:
IntCollection
Direct Known Subclasses:
ArrayUnsignedShortList, IntCollectionImpl, ArrayIntList, AbstractRandomAccessIntListImpl, RandomAccessIntSubList, RandomAccessIntList
Abstract base class for
IntCollection s.
Read-only subclasses must override
#iterator
and
#size . Mutable subclasses
should also override
#add and
IntIterator.remove .
All other methods have at least some base implementation
derived from these. Subclasses may choose to override
these methods to provide a more efficient implementation.
