Returns the Content-Format code of the resource.
The Content-Format code corresponds to the 'ct' attribute and provides a hint about the Content-Formats this resource returns. It is specified in RFC 7252 .

Returns the interface description of the resource.
The Interface Description 'if' attribute is an opaque string used to provide a name or URI indicating a specific interface definition used to interact with the target resource. It is specified in RFC 6690 .
另请参阅 setInterface ().
Returns the maximum size of the resource.
The maximum size estimate attribute 'sz' gives an indication of the maximum size of the resource representation returned by performing a GET on the target URI. It is specified in RFC 6690 .

Sets the content format of the resource to contentFormat . The content format can be one of the content formats defined in CoAP Content-Formats Registry .
注意: CoAP supports common content formats such as XML, JSON, and so on, but these are text based and consequently heavy both in payload and in processing. One of the recommended content formats to use with CoAP is CBOR, which is designed to be used in such contexts.
