equals
public boolean equals(Object o)
Compares the specified object with this list for equality. Returnstrue
if and only if the specified object is also anIntegerList
, both lists have the same size, and all corresponding pairs of elements in the two lists are equal. In other words, two lists are defined to be equal if they contain the same elements in the same order.This implementation first checks if the specified object is this list. If so, it returns
true
; if not, it checks if the specified object is anIntegerList
. If not, it returnsfalse
; if so, it checks the size of both lists. If the lists are not the same size, it returnsfalse
; otherwise it iterates over both lists, comparing corresponding pairs of elements. If any comparison returnsfalse
, this method returnsfalse
.
-
hashCode
public int hashCode()
Returns the hash code value for this list.This implementation uses exactly the code that is used to define the list hash function in the documentation for the
List.hashCode()
method.
-
toString
public String toString()
Returns a string representation of this list.
-
binarySearch
public final int binarySearch(int key)
-
binarySearch
public final int binarySearch(int fromIndex, int toIndex, int key)
-
toCharArray
public final char[] toCharArray()
Convert the int list to a char array where values > 0x7FFFF take 2 bytes. TODO????? If all values are less than the 0x7FFF 16-bit code point limit (1 bit taken to indicatethen this is just a char array of 16-bit char as usual. For values in the supplementary range, encode them as two UTF-16 code units.
