Detailed Description¶

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.

See also

isValid()

__init__(other)

Parameters:: other – QNetworkCacheMetaData

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.

See also

setAttributes() Attribute

expirationDate()¶

Return type:: QDateTime

Returns the date and time when the meta data expires.

See also

setExpirationDate()

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.

See also

setLastModified()

__ne__(other)¶

Parameters:: other – QNetworkCacheMetaData
Return type:: bool

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

See also

operator==()

__eq__(other)¶

Parameters:: other – QNetworkCacheMetaData
Return type:: bool

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

See also

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.

See also

setRawHeaders() headers()

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.

setSaveToDisk()

setAttributes(attributes)¶

Parameters:: attributes – Dictionary with keys of type .QNetworkRequest.Attribute and values of type QVariant.

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

See also

attributes() setAttribute()

setExpirationDate(dateTime)¶

Parameters:: dateTime – QDateTime

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

See also

expirationDate()

setHeaders(headers)¶

Parameters:: headers – QHttpHeaders

Sets the headers of this network cache meta data to headers.

See also

headers()

setLastModified(dateTime)¶

Parameters:: dateTime – QDateTime

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

See also

lastModified()

setRawHeaders(headers)¶

Parameters:: headers – .list of std.pairQByteArray,QByteArray

Sets the raw headers to list.

See also

rawHeaders() setHeaders()

setSaveToDisk(allow)¶

Parameters:: allow – bool

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

setUrl(url)¶

Parameters:: url – QUrl

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

The password and fragment are removed from the url.

url()

swap(other)¶

Parameters:: other – QNetworkCacheMetaData

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

url()¶

Return type:: QUrl

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