java.lang.Objectjava.text.CollationKey
public class CollationKey
This class represents a pre-computed series of bits representing a
String for under a particular Collator. This
value may be compared bitwise against another CollationKey
representing a different String under the same
Collator in a manner than is usually more efficient than
using the raw Collator compare methods. There is overhead
associated with calculating this value, so it is generally not
advisable to compute CollationKey's unless multiple
comparisons against a String will be done. (For example,
in a sort routine).
This class cannot be instantiated directly. Instead, a
CollationKey is created by calling the
getCollationKey method on an instance of Collator.

public int compareTo(CollationKey ck)
compareTo in interface Comparable<CollationKey>ck - The CollationKey to compare against this one.
public boolean equals(Object obj)
Object for equality with
this object. This will be true if and only if:
nullCollationKey.Collator
as this object.
equals in class Objectobj - The Object to test for equality.
true if the specified object is equal to this one, false otherwise.Object.hashCode()public String getSourceString()
String that this object was created
from.
String for this object.public int hashCode()
