Cleanup warnings in java.util.Collections.
2016-03-18 Andrew John Hughes <gnu_and...@member.fsf.org>
Cleanup warnings in java.util.Collections.
* java/util/Collections.java:
(EMPTY_SET): Suppress warnings generated by this
legacy raw type.
(EMPTY_LIST): Likewise.
(EMPTY_MAP): Likewise.
(compare(T, T, Comparator): Suppress warning
generated by casting to Comparable.
(binarySearch(List, Comparator)): Remove unneeded
casts.
(reverse(List)): Suppress warnings when casting
to ListIterator<Object>. Cast is necessary as
lists are modified.
(reverseOrder(Comparator)): Return reverseOrder()
rather than rcInstance.
(reverseOrder()): Create appropriately typed
ReverseComparator rather than using set instance.
(rcInstance): Removed.
(ReverseComparator.compare(T,T)): Suppress warnings
from casting to Comparable<T>.
(rotate(List,int)): Suppress warnings when casting
to List<Object>. Cast is necessary to modify list.
(shuffle(List,Random)): Likewise.
(disjoint(Collection,Collection)): Remove unnecessary
casting.
(sort(List,Comparator)): Suppress warnings when casting
the returned array. Arrays of a generic type can not
be created.
(swap(List,int,int)): Suppress warnings when casting
list to List<Object>. This is necessary to use the
set method.
(entrySet().SynchronizedMapEntry): Type should not have its
own type parameters which hide those of the map.
(entrySet().SynchronizedSet.iterator()): Remove type
parameters from SynchronizedMapEntry creation.
(UnmodifiableList.list): Retain input type parameter
so as to avoid casting.
(UnmodifiableList.UnmodifiableList): Remove cast.
(UnmodifiableList.li): Retain input type parameter
so as to avoid casting.
(UnmodifiableListIterator(ListIterator)): Likewise.
(UnmodifiableMap(Map)): Suppress warnings from casting
down to Map<K,V>.
(UnmodifiableMap.entrySet()): Remove type parameters
from UnmodifiableEntrySet creation.
(UnmodifiableMap.UnmodifiableEntrySet): Remove type
parameters and make instance-specific so we can
use the UnmodifiableMap's type parameters.
(UnmodifiableMap.UnmodifiableEntrySet.UnmodifiableMapEntry):
Likewise.
(UnmodifiableMap.UnmodifiableEntrySet.UnmodifiableMapEntry.e):
Retain input type parameters so as to avoid casting.
(UnmodifiableMap.UnmodifiableEntrySet.UnmodifiableMapEntry.UnmodifiableMapEntry(Map.Entry)):
Likewise.
(UnmodifiableMap.UnmodifiableEntrySet.UnmodifiableEntrySet(Set)):
Likewise.
(UnmodifiableMap.UnmodifiableEntrySet.UnmodifiableIterator.next()):
Remove type parameters from UnmodifiableMapEntry creation.
(UnmodifiableMap.toArray()): Likewise and improve method
structure.
(UnmodifiableMap.toArray(S[])): Remove type parameters from
UnmodifiableMapEntry and suppress warnings from casting
array members.
(UnmodifiableSortedMap.sm): Retain input type parameters
so as to avoid casting.
(UnmodifiableSortedMap.UnmodifiableSortedMap(SortedMap)):
Remove cast.
(CheckedList.addAll(int,Collection)): Replace iterator with for-each
loop, removing the need for casting.
(CheckedMap.entrySet()): Remove type parameters from CheckedEntrySet
creation and klass argument.
(CheckedMap.CheckedEntrySet): Don't create additional
type parameters, use those of the containing map as
a instance class, not a static class.
(keyType): Type should be K to match enclosing CheckedMap.
(valueType): Type should be V to match enclosing CheckedMap.
(CheckedMap.CheckedEntrySet.CheckedEntrySet(Set,Class,Class)):
Suppress warnings when casting Map.Entry class.
(CheckedMap.CheckedEntrySet.iterator()): Make return type
Map.Entry<K,V> and create corresponding CheckedIterator instance.
(CheckedMap.CheckedEntrySet.CheckedIterator.next()): Likewise
with Map.Entry instance.
(CheckedMap.CheckedEntrySet.CheckedIterator.Map.Entry.getKey()):
Make return type K.
(CheckedMap.CheckedEntrySet.CheckedIterator.Map.Entry.getValue()):
Make return type V.
(CheckedMap.CheckedEntrySet.CheckedIterator.Map.Entry.setValue(Object)):
Likewise.
(CheckedMap.putAll(Map)): Use for-each loop instead of Iterator,
avoiding casting.
