Method Detail

equals

public boolean equals(HashedSequence<S> a,
                      int ai,
                      HashedSequence<S> b,
                      int bi)

Description copied from interface: SequenceComparator

Compare two items to determine if they are equivalent.

Specified by:

equals in interface SequenceComparator<HashedSequence<S extends Sequence>>

hash

public int hash(HashedSequence<S> seq,
                int i)

Description copied from interface: SequenceComparator

Get a hash value for an item in a sequence. If two items are equal according to this comparator's SequenceComparator.equals(Sequence, int, Sequence, int) method, then this hash method must produce the same integer result for both items. However not required to have different hash values for different items.
