Method Detail

equates

public final boolean equates(byte[] a,
                             byte[] b)

Description copied from interface: Equality

Returns a boolean indicating if the two parameters are considered equal by this Equality

Specified by:

equates in interface Equality<byte[]>

Parameters:

a - an Object of type E

b - another Object of type E

Returns:

true if this equality equates the two arguments

hash

public final int hash(byte[] k)

Description copied from interface: Equality

Returns the hash value of the object as defined by this Equality. For all objects this Equality can be applied to, it should be the case that equates(a, b) ==> hash(a) == hash(b)

Specified by:

hash in interface Equality<byte[]>

Parameters:

k - an Object of type E

Returns:

the hash of the parameter
