* Apex doesn't expose dependent picklist info directly, but it's possible to expose. | |
* Approach: | |
* * Schema.PicklistEntry doesn't expose validFor tokens, but they are there, and can be accessed by serializing to JSON | |
* (and then for convenience, deserializing back into an Apex POJO) | |
* * validFor tokens are converted from base64 representations (e.g. gAAA) to binary (100000000000000000000) | |
* each character corresponds to 6 bits, determined by normal base64 encoding rules. | |
* * The binary bits correspond to controlling values that are active - e.g. in the example above, this dependent option | |
* is available for the first controlling field only. | |
