Member Function Documentation▲
QNetworkCacheMetaData::QNetworkCacheMetaData()▲
QNetworkCacheMetaData::QNetworkCacheMetaData(const QNetworkCacheMetaData &other)▲
Constructs a copy of the other QNetworkCacheMetaData.
QNetworkCacheMetaData::~QNetworkCacheMetaData()▲
Destroys the network cache meta data.
QNetworkCacheMetaData::AttributesMap QNetworkCacheMetaData::attributes() const▲
Returns all the attributes stored with this cache item.
See Also▲
See also setAttributes(), QNetworkRequest::Attribute
QDateTime QNetworkCacheMetaData::expirationDate() const▲
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▲
See also setLastModified()
QNetworkCacheMetaData::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▲
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 with Cache-control set to no-store or any https document that doesn't have "Cache-control: public" set will set the saveToDisk to false.

void QNetworkCacheMetaData::setAttributes(const QNetworkCacheMetaData::AttributesMap &attributes)▲
Sets all attributes of this cache item to be the map attributes.
