## Clear

  - *notes:* Clear the specified names from the per-thread map.
@param names The names to be removed from the map.

## UnsetOrLoad

Reads a long variable from the input, hashes and scales it to the unit interval 0.0d - 1.0d, then uses the result to determine whether to return UNSET.value or a loaded value.

- long -> UnsetOrLoad(double: ratio, java.lang.String: varname) -> java.lang.Object


## UnsetOrPass

Reads a long variable from the thread local variable map, hashes and scales it to the unit interval 0.0d - 1.0d, then uses the result to determine whether to return UNSET.value or the input value.

- java.lang.Object -> UnsetOrPass(double: ratio, java.lang.String: varname) -> java.lang.Object
