Function checkJmapId

checkJmapId(id, message?): void
JMap.Util.checkJmapId

Throws an Error if the passed Id is not a valid JMap Id, otherwise does nothing. You can use this method as a safeguard in your methods that accept JMap Ids. JMap.Util.checkJmapId always run a strict check on the passed value, i.e. the string "123" will not pass.

- id: any
  The JMap Id to validate
- Optional message: string
  Optional message that will be used in the thrown error if the passed value doesn't pass the check.

JMap.Util.checkJmapId("", "My custom error message")
// Error thrown "My custom error message"

JMap.Util.checkJmapId(4)
// undefined
