Detailed Description

The QNetworkCacheMetaData class provides cache information. QNetworkCacheMetaData provides information about a cache file including the url, when it was last modified, when the cache file was created, headers for file and if the file should be saved onto a disk.

Constructor & Destructor 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.

Method Documentation

AttributesMap QNetworkCacheMetaData::attributes ( ) const

Returns all the attributes stored with this cache item.

See also: setAttributes(), 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()

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

inline

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

See also: operator==()

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

Copy assigns from other and returns a reference to this object.

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

inline

Move assigns from other and returns a reference to this object.

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!=()

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 does not 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.

See also: attributes(), 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 current URL for this metadata to url. The password and fragment are removed from the given url.

See also: url()

void QNetworkCacheMetaData::swap ( QNetworkCacheMetaData & other )

inline

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

QUrl QNetworkCacheMetaData::url ( ) const

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

See also: setUrl()
