QCoapResource:: QCoapResource (const QCoapResource & other )

Constructs a new CoAP resource as a copy of other , making the two resources identical.

QCoapResource:: QCoapResource ()

Constructs a new QCoapResource.

QCoapResource &QCoapResource:: operator= (const QCoapResource & other )

拷贝 other into this resource, making the two resources identical. Returns a reference to this QCoapResource .

QCoapResource:: ~QCoapResource ()

Destroy the QCoapResource .

uint QCoapResource:: contentFormat () const

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 .

另请参阅 setContentFormat ().

QHostAddress QCoapResource:: host () const

Returns the host of the resource.

另请参阅 setHost ().

QString QCoapResource:: interface () const

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 ().

int QCoapResource:: maximumSize () const

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 .

另请参阅 setMaximumSize ().

bool QCoapResource:: observable () const

返回 true if the resource is observable

另请参阅 setObservable ().

QString QCoapResource:: path () const

Returns the path of the resource.

另请参阅 setPath ().

QString QCoapResource:: resourceType () const

Returns the type of the resource.

另请参阅 setResourceType ().

void QCoapResource:: setContentFormat ( uint contentFormat )

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.

另请参阅 contentFormat (), QCborStreamWriter ，和 QCborStreamReader .

void QCoapResource:: setHost (const QHostAddress & host )

Sets the host of the resource to host .

另请参阅 host ().

void QCoapResource:: setInterface (const QString & interface )

Sets the interface of the resource to interface .

另请参阅 interface ().

void QCoapResource:: setMaximumSize ( int maximumSize )

Sets the maximum size of the resource to maximumSize .

另请参阅 maximumSize ().
