Method Detail

equal

public final boolean equal(java.lang.Object a,
                           java.lang.Object b)

Description copied from interface: CustomConcurrentHashMap.Equivalence

Returns true if the given objects are considered equal. This function must obey an equivalence relation: equal(a, a) is always true, equal(a, b) implies equal(b, a), and (equal(a, b) && equal(b, c) implies equal(a, c). Note that the second argument need not be known to have the same declared type as the first.

Specified by:

equal in interface CustomConcurrentHashMap.Equivalence<java.lang.Object>

Parameters:

a - a key in, or being placed in, the map

b - an object queried for membership

Returns:

true if considered equal

hash

public final int hash(java.lang.Object a)

Description copied from interface: CustomConcurrentHashMap.Equivalence

Returns a hash value such that equal(a, b) implies hash(a)==hash(b).

Specified by:

hash in interface CustomConcurrentHashMap.Equivalence<java.lang.Object>

Parameters:

a - an object queried for membership

Returns:

a hash value
