示例1: getGroupName
import ca.nrc.cadc.util.StringUtil; //导入依赖的package包/类
public final String getGroupName() {
// canonical form: ivo://<authority>/<path>?<name>
String ret = groupID.getQuery();
if (StringUtil.hasText(ret)) {
return ret;
}
// backwards compat
ret = groupID.getFragment();
if (StringUtil.hasText(ret)) {
return ret;
}
// temporary backwards compat for caom2ac usage hack
return groupID.toASCIIString();
}
