Get rich versions from toml


I would like to get the strictly/preferred/required version I created in the toml file. How is this possible?
Example toml:

groovy = { strictly = "[2.5,3.0)", prefer = "2.5.13" }

I saw the current implementation from the versions is:

 private String doGetVersion(String name) {
            ImmutableVersionConstraint version = findVersionConstraint(name);
            String requiredVersion = version.getRequiredVersion();
            if (!requiredVersion.isEmpty()) {
                return requiredVersion;
            String strictVersion = version.getStrictVersion();
            if (!strictVersion.isEmpty()) {
                return strictVersion;
            return version.getPreferredVersion();

I would like to just get e.g. the strict version.
How can I achieve this?
