QNetworkCacheMetaData Class

Member Function Documentation

QNetworkCacheMetaData::QNetworkCacheMetaData()

Constructs an invalid network cache meta data.

See also isValid().

QNetworkCacheMetaData::QNetworkCacheMetaData(const QNetworkCacheMetaData &other)

Constructs a copy of the other QNetworkCacheMetaData.

QNetworkCacheMetaData::~QNetworkCacheMetaData()

Destroys the network cache meta data.

AttributesMap QNetworkCacheMetaData::attributes() const

Returns all the attributes stored with this cache item.

This function was introduced in Qt 4.6.

See also setAttributes() and QNetworkRequest::Attribute.

QDateTime QNetworkCacheMetaData::expirationDate() const

Returns the date and time when the meta data expires.

See also setExpirationDate().

bool QNetworkCacheMetaData::isValid() const

Returns true if this network cache meta data has attributes that have been set otherwise false.

QDateTime QNetworkCacheMetaData::lastModified() const

Returns the date and time when the meta data was last modified.

See also setLastModified().

RawHeaderList QNetworkCacheMetaData::rawHeaders() const

Returns a list of all raw headers that are set in this meta data. The list is in the same order that the headers were set.

See also setRawHeaders().

bool QNetworkCacheMetaData::saveToDisk() const

Returns is this cache should be allowed to be stored on disk.

Some cache implementations can keep these cache items in memory for performance reasons, but for security reasons they should not be written to disk.

Specifically with http, documents marked with Pragma: no-cache, or have a Cache-control set to no-store or no-cache or any https document that doesn't have "Cache-control: public" set will set the saveToDisk to false.

See also setSaveToDisk().

void QNetworkCacheMetaData::setAttributes(const AttributesMap &attributes)

Sets all attributes of this cache item to be the map attributes.

This function was introduced in Qt 4.6.

See also attributes() and QNetworkRequest::setAttribute().

void QNetworkCacheMetaData::setExpirationDate(const QDateTime &dateTime)

Sets the date and time when the meta data expires to dateTime.

See also expirationDate().

void QNetworkCacheMetaData::setLastModified(const QDateTime &dateTime)

Sets the date and time when the meta data was last modified to dateTime.

See also lastModified().

void QNetworkCacheMetaData::setRawHeaders(const RawHeaderList &list)

Sets the raw headers to list.

See also rawHeaders().

void QNetworkCacheMetaData::setSaveToDisk(bool allow)

Sets whether this network cache meta data and associated content should be allowed to be stored on disk to allow.

See also saveToDisk().

void QNetworkCacheMetaData::setUrl(const QUrl &url)

Sets the URL this network cache meta data to be url.

The password and fragment are removed from the url.

See also url().

void QNetworkCacheMetaData::swap(QNetworkCacheMetaData &other)

Swaps this metadata instance with other. This function is very fast and never fails.

This function was introduced in Qt 5.0.

QUrl QNetworkCacheMetaData::url() const

Returns the URL this network cache meta data is referring to.

See also setUrl().

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

Returns true if this meta data is not equal to the other meta data; otherwise returns false.

See also operator==().

QNetworkCacheMetaData &QNetworkCacheMetaData::operator=(QNetworkCacheMetaData &&other)

Move-assignment operator.

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

Makes a copy of the other QNetworkCacheMetaData and returns a reference to the copy.

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

Returns true if this meta data is equal to the other meta data; otherwise returns false.

See also operator!=().
