binarySearch	back to summary
public static <E extends @Nullable Object> int binarySearch(List<? extends E> list, E key, Comparator<? super E> comparator, SortedLists.KeyPresentBehavior presentBehavior, SortedLists.KeyAbsentBehavior absentBehavior) Searches the specified list for the specified object using the binary search algorithm. The list must be sorted into ascending order according to the specified comparator (as by the `Collections.sort(List, Comparator)` method), prior to making this call. If it is not sorted, the results are undefined. If there are elements in the list which compare as equal to the key, the choice of `KeyPresentBehavior` decides which index is returned. If no elements compare as equal to the key, the choice of `KeyAbsentBehavior` decides which index is returned. This method runs in log(n) time on random-access lists, which offer near-constant-time access to each list element. Parameters list:List<? extends E> the list to be searched. key:E the value to be searched for. comparator:Comparator<? super E> the comparator by which the list is ordered. presentBehavior:SortedLists.KeyPresentBehavior the specification for what to do if at least one element of the list compares as equal to the key. absentBehavior:SortedLists.KeyAbsentBehavior the specification for what to do if no elements of the list compare as equal to the key. Returns:int the index determined by the `KeyPresentBehavior`, if the key is in the list; otherwise the index determined by the `KeyAbsentBehavior`.

public static <E extends @Nullable Object> int binarySearch(List<? extends E> list, E key, Comparator<? super E> comparator, SortedLists.KeyPresentBehavior presentBehavior, SortedLists.KeyAbsentBehavior absentBehavior)

Searches the specified list for the specified object using the binary search algorithm. The list must be sorted into ascending order according to the specified comparator (as by the Collections.sort(List, Comparator) method), prior to making this call. If it is not sorted, the results are undefined.

If there are elements in the list which compare as equal to the key, the choice of KeyPresentBehavior decides which index is returned. If no elements compare as equal to the key, the choice of KeyAbsentBehavior decides which index is returned.

This method runs in log(n) time on random-access lists, which offer near-constant-time access to each list element.

Parameters

list:List<? extends E>: the list to be searched.
key:E: the value to be searched for.
comparator:Comparator<? super E>: the comparator by which the list is ordered.
presentBehavior:SortedLists.KeyPresentBehavior: the specification for what to do if at least one element of the list compares as equal to the key.
absentBehavior:SortedLists.KeyAbsentBehavior: the specification for what to do if no elements of the list compare as equal to the key.

Returns:int

the index determined by the KeyPresentBehavior, if the key is in the list; otherwise the index determined by the KeyAbsentBehavior.

INVERTED_INSERTION_INDEX back to summary

INVERTED_INSERTION_INDEX	back to summary
public static final SortedLists.KeyAbsentBehavior INVERTED_INSERTION_INDEX Return `~insertionIndex`, where `insertionIndex` is defined as the point at which the key would be inserted into the list: the index of the next higher element in the list, or `list.size()` if there is no such element. Note that the return value will be `>= 0` if and only if there is an element of the list that compares as equal to the key. This is equivalent to the behavior of `java.util.Collections#binarySearch(List, Object)` when the key isn't present, since `~insertionIndex` is equal to `-1 - insertionIndex`.

public static final SortedLists.KeyAbsentBehavior INVERTED_INSERTION_INDEX

Return ~insertionIndex, where insertionIndex is defined as the point at which the key would be inserted into the list: the index of the next higher element in the list, or list.size() if there is no such element.

Note that the return value will be >= 0 if and only if there is an element of the list that compares as equal to the key.

This is equivalent to the behavior of java.util.Collections#binarySearch(List, Object) when the key isn't present, since ~insertionIndex is equal to -1 - insertionIndex.
