psidev.psi.mi.jami.utils.comparator.xref.ExactExternalIdentifierComparator

All Implemented Interfaces:

Comparator<Xref>

public class ExactExternalIdentifierComparator
extends UnambiguousExternalIdentifierComparator

Exact comparator for external identifiers (Xref database and id). It compares first the databases using UnambiguousCvTermComparator, then the ids (case sensitive) and then the version. To compare the databases, it looks first at the PSI-MI ids if at least one of the database has a PSI-MI id, otherwise it looks at the database shortlabel only. - Two external identifiers which are null are equals - The external identifier which is not null is before null. - If the two external identifiers are set : - compare the databases. If both databases are equal, compare the ids (is case sensitive) - if both ids are the same, compares the versions.

Method Detail

compare

public int compare(Xref externalIdentifier1,
                   Xref externalIdentifier2)

It compares first the databases using UnambiguousCvTermComparator, then the ids (case sensitive) and then the version. To compare the databases, it looks first at the PSI-MI ids if at least one of the database has a PSI-MI id, otherwise it looks at the database shortlabel only. - Two external identifiers which are null are equals - The external identifier which is not null is before null. - If the two external identifiers are set : - compare the databases. If both databases are equal, compare the ids (is case sensitive) - if both ids are the same, compares the versions.

Specified by:

compare in interface Comparator<Xref>

Overrides:

compare in class UnambiguousExternalIdentifierComparator

Parameters:

externalIdentifier1 - a Xref object.

externalIdentifier2 - a Xref object.

Returns:

a int.

                                Xref externalIdentifier2)

Use ExactExternalIdentifierComparator to know if two external identifiers are equals.

hashCode
