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.

__init__()

Constructs an invalid network cache meta data.

isValid()

__init__(other)
Parameters:

otherQNetworkCacheMetaData

Constructs a copy of the other QNetworkCacheMetaData .

attributes()
Return type:

Dictionary with keys of type .QNetworkRequest.Attribute and values of type QVariant.

Returns all the attributes stored with this cache item.

expirationDate()
Return type:

QDateTime

Returns the date and time when the meta data expires.

headers()
Return type:

QHttpHeaders

Returns headers in form of QHttpHeaders that are set in this meta data.

See also

setHeaders()

isValid()
Return type:

bool

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

lastModified()
Return type:

QDateTime

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

__ne__(other)
Parameters:

otherQNetworkCacheMetaData

Return type:

bool

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

operator==()

__eq__(other)
Parameters:

otherQNetworkCacheMetaData

Return type:

bool

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

operator!=()

rawHeaders()
Return type:

.list of std.pairQByteArray,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.

saveToDisk()
Return type:

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 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.
