Interface HardLinkIdentitySupplier

All Known Implementing Classes:
PlexusIoFileResource, PlexusIoSymlinkResource
public interface HardLinkIdentitySupplier
Optional identity for resources whose contents can share one hard-link payload. Implementations must return null when transformation or a replacement content supplier invalidates that relationship. Equal identities must denote the same content within a stable source, not merely equal bytes from unrelated files. Consumers must also compare the metadata they intend to write.

3.7.1
