详细描述

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 枚举。

QCoapOption:: QCoapOption ( QCoapOption && other )

Move-constructs a QCoapOption, making it point to the same object as other 所指向的。

QCoapOption:: QCoapOption (const QCoapOption & other )

Constructs a new CoAP option as a copy of other , making the two options identical.

另请参阅 isValid ().

QCoapOption:: QCoapOption ( QCoapOption::OptionName name , quint32 intValue )

Constructs a new CoAP option with the given name and the unsigned integer intValue .

另请参阅 isValid ().

QCoapOption:: QCoapOption ( QCoapOption::OptionName name , const QString & stringValue )

Constructs a new CoAP option with the given name 和 QString stringValue .

另请参阅 isValid ().

QCoapOption:: QCoapOption ( QCoapOption::OptionName name = Invalid, const QByteArray & opaqueValue = QByteArray())

Constructs a new CoAP option with the given name and QByteArray opaqueValue . If no parameters are passed, constructs an Invalid object.

另请参阅 isValid ().

QCoapOption &QCoapOption:: operator= ( QCoapOption && other )

移动赋值运算符。

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

拷贝 other into this option, making the two options identical. Returns a reference to this QCoapOption .

QCoapOption:: ~QCoapOption ()

销毁 QCoapOption 对象。

bool QCoapOption:: isValid () const

返回 true if the option is valid.

int QCoapOption:: length () const

Returns the length of the value of the option.

QCoapOption::OptionName QCoapOption:: name () const

QString QCoapOption:: stringValue () const

返回 QString value of the option.

void QCoapOption:: swap ( QCoapOption & other )

Swaps this option with other 。此操作非常快且从不失败。

quint32 QCoapOption:: uintValue () const

Returns the integer value of the option.

bool QCoapOption:: operator!= (const QCoapOption & other ) const

返回 true 若此 QCoapOption and other are different.

bool QCoapOption:: operator== (const QCoapOption & other ) const

返回 true 若此 QCoapOption and other are equals.
