Expand description

An error encountered while parsing the value or format of a property.

Variants§

§

Unknown

The value of the property or attribute is not yet known, or not set by the device.

§

WrongDatatype

The method call expected the property to have a particular datatype, but the datatype sent by the device was something different.

Fields

§expected: Datatype

The datatype expected by the method call.

§actual: Datatype

The actual datatype of the property, as sent by the device.

§

WrongFormat

The format of the property couldn’t be parsed or didn’t match what was expected by the method call.

Fields

§format: String

The format string of the property.

§

ParseFailed

The value of the property couldn’t be parsed as the expected type.

Fields

§value: String

The string value of the property.

§datatype: Datatype

The datatype as which the value was attempted to be parsed.
