Properties

_dataType

• Optional Readonly _dataType: E

Type of the Events which may be returned by the contained tags. Note that this does reflect only locally declared type knowledge; historic events delivered by the Actyx system may not match these types, and this is not automatically detected. It is therefore good practice to carefully review changes to the declared type so that they remain backwards compatible.
