[GitHub] [arrow] sgilmore10 opened a new issue, #37251: [MATLAB] Remove `arrow.type.TemporalType` superclass temporarily

["sgilmore10 (via GitHub)" <gi...@apache.org>]

sgilmore10 opened a new issue, #37251:
URL: https://github.com/apache/arrow/issues/37251

   ### Describe the enhancement requested
   
   Our original motivation for adding the super-class `arrow.type.TemporalType` in #37236 was to define a common implementation for extracting the `Unit` property from `TimestampType`, `Time32Type`, `Time64Type`, `Date32Type`, and `Date64Type`. However, this approach doesn't work because the `Unit` property on `Date32Type` and `Date64Type` is a `DateUnit`, while the `Unit` property on the other three types is a`TimeUnit`. This means we can't define a method for extracting the `Unit` property within `TemporalType`. 
   
   For now, we plan on removing the `TemporalType` class since it won't defined any shared functionality. 
   
   However, in the future, we would like add `TemporalType` back as a "mixin" class for type-checking purposes. We would also add a function called `arrow.type.isTemporal(arrowType)` that would return `true` if the `arrowType` class inherits from `TemporalType`.
