KDE 4.3 PyKDE API Reference
ItemFetchScope Class Reference
from PyKDE4.akonadi import *
Namespace: Akonadi
Detailed Description
Specifies which parts of an item should be fetched from the Akonadi storage.
When items are fetched from server either by using ItemFetchJob explicitly or when it is being used internally by other classes, e.g. ItemModel, the scope of the fetch operation can be tailored to the application's current needs.
There are two supported ways of changing the currently active ItemFetchScope of classes: - in-place: modify the ItemFetchScope object the other class holds as a member - replace: replace the other class' member with a new scope object
Example: modifying an ItemFetchJob's scope in-place
Akonadi.ItemFetchJob *job = new Akonadi.ItemFetchJob( collection ); job->fetchScope().fetchFullPayload(); job->fetchScope().fetchAttribute<MyAttribute>();
Example: replacing an ItemFetchJob's scope
Akonadi.ItemFetchScope scope; scope.fetchFullPayload(); scope.fetchAttribute<MyAttribute>(); Akonadi.ItemFetchJob *job = new Akonadi.ItemFetchJob( collection ); job->setFetchScope( scope );
This class is implicitly shared.

Method Documentation
| __init__ | ( | self ) |
Creates an empty item fetch scope.
Using an empty scope will only fetch the very basic meta data of items, e.g. local id, remote id and mime type
| __init__ | ( | self, | ||
| Akonadi.ItemFetchScope | other | |||
| ) |
Creates a new item fetch scope from an other.
| bool allAttributes | ( | self ) |
Returns whether all available attributes should be fetched.
- See also:
- fetchAllAttributes()
| QSet |
( | self ) |
Returns all explicitly fetched attributes.
Undefined if fetchAllAttributes() returns true.
- See also:
- fetchAttribute()
| bool cacheOnly | ( | self ) |
Returns whether payload data should be requested from remote sources or just from the local cache.
- See also:
- setCacheOnly()
| fetchAllAttributes | ( | self, | ||
| bool | fetch=1 | |||
| ) |
Sets whether all available attributes should be fetched.
- Parameters:
-
fetch true if all available attributes should be fetched, false otherwise.
| fetchAttribute | ( | self, | ||
| QByteArray | type, | |||
| bool | fetch=1 | |||
| ) |
Sets whether the attribute of the given type should be fetched.
- Parameters:
-
type The attribute type to fetch. fetch true if the attribute should be fetched, false otherwise.
| fetchFullPayload | ( | self, | ||
| bool | fetch=1 | |||
| ) |
Sets whether the full payload shall be fetched.
- Parameters:
-
fetch true if the full payload should be fetched, false otherwise.
| fetchPayloadPart | ( | self, | ||
| QByteArray | part, | |||
| bool | fetch=1 | |||
| ) |
Sets which payload parts shall be fetched.
- Parameters:
-
part The payload part identifier. Valid values depend on the item type. fetch true to fetch this part, false otherwise.
| bool fullPayload | ( | self ) |
Returns whether the full payload should be fetched.
- See also:
- fetchFullPayload()
| bool isEmpty | ( | self ) |
Returns true if there is nothing to fetch.
| QSet |
( | self ) |
Returns the payload parts that should be fetched.
- See also:
- fetchPayloadPart()
| setCacheOnly | ( | self, | ||
| bool | cacheOnly | |||
| ) |
Sets whether payload data should be requested from remote sources or just from the local cache.
- Parameters:
-
cacheOnly true if no remote data should be requested,
false otherwise (the default).
