has method
Returns if other
is a possible resolution of this
.
For example, a TarFormat with a value of 6 means that we do not have
enough information to determine if it is TarFormat.ustar or
TarFormat.pax, so either of them could be possible resolutions of
this
.
Implementation
@override
bool has(MaybeTarFormat other) {
return other == this;
}
