Class AbstractBooleanList
- All Implemented Interfaces:
BooleanCollection
,BooleanIterable
,BooleanList
,BooleanStack
,Stack<Boolean>
,Comparable<List<? extends Boolean>>
,Iterable<Boolean>
,Collection<Boolean>
,List<Boolean>
,SequencedCollection<Boolean>
- Direct Known Subclasses:
AbstractBooleanList.BooleanSubList
,BooleanArrayList
,BooleanImmutableList
,BooleanLists.Singleton
As an additional bonus, this class implements on top of the list operations a type-specific stack.
Most of the methods in this class are optimized with the assumption that the List will have
have constant-time random access
. If this is not the case, you
should probably at least override listIterator(int)
and the xAll()
methods (such as addAll(int, java.util.Collection<? extends java.lang.Boolean>)
) with a more appropriate iteration scheme. Note the
subList(int, int)
method is cognizant of random-access or not, so that need not be
reimplemented.
