QNetworkCacheMetaData¶

PyQt5.QtNetwork.QNetworkCacheMetaData

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.

Methods¶

__init__(): Constructs an invalid network cache meta data.

See also

isValid().

__init__(QNetworkCacheMetaData): Constructs a copy of the other QNetworkCacheMetaData.

attributes() → Dict[Attribute, Any]: Returns all the attributes stored with this cache item.

See also

setAttributes(), Attribute.

__eq__(QNetworkCacheMetaData) → bool: TODO

expirationDate() → QDateTime: Returns the date and time when the meta data expires.

See also

setExpirationDate().

isValid() → bool: Returns true if this network cache meta data has attributes that have been set otherwise false.

lastModified() → QDateTime: Returns the date and time when the meta data was last modified.

See also

setLastModified().

__ne__(QNetworkCacheMetaData) → bool: TODO

rawHeaders() → List[Tuple[QByteArray, QByteArray]]: 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().

saveToDisk() → bool

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 to false.
