doEquivalent

protected boolean doEquivalent(java.lang.Iterable<T> iterableA,
                               java.lang.Iterable<T> iterableB)

Description copied from class: Equivalence

Implemented by the user to determine whether a and b are considered equivalent, subject to the requirements specified in Equivalence.equivalent(T, T).

This method should not be called except by Equivalence.equivalent(T, T). When Equivalence.equivalent(T, T) calls this method, a and b are guaranteed to be distinct, non-null instances.

Specified by:

doEquivalent in class Equivalence<java.lang.Iterable<T>>

doHash

protected int doHash(java.lang.Iterable<T> iterable)

Description copied from class: Equivalence

Implemented by the user to return a hash code for t, subject to the requirements specified in Equivalence.hash(T).

This method should not be called except by Equivalence.hash(T). When Equivalence.hash(T) calls this method, t is guaranteed to be non-null.

Specified by:
