Detailed Description

CoAP defines a number of options that can be included in a message. Both requests and responses may include a list of one or more options. For example, the URI in a request is transported in several options, and metadata that would be carried in an HTTP header in HTTP is supplied as options as well.

An option contains a name, related to an option ID, and a value. The name is one of the values from the OptionName enumeration.

class OptionName

Indicates the name of an option. The value of each ID is as specified by the CoAP standard, with the exception of Invalid. You can refer to RFC 7252 and RFC 7959 for more details.
