* Make EmptySkyValue not serializableGravatar Michajlo Matijkiw2015-10-21
| | | | | | | | Should be a singleton, should never be serialized or deserialized, but add equals and hash code as well for good measure. -- MOS_MIGRATED_REVID=105888511
* Refactor cycle related skyvalues to use shared empty valueGravatar Michajlo Matijkiw2015-10-13
Previously the cycle values (were supposed to) share a common abstract base class, however usage was inconsistent. Instead refactor to eliminate the specialized value classes, remove the abstract class, and share a common empty placeholder value, which should be useful for future/other current empty values. -- MOS_MIGRATED_REVID=105217399
