Is called, whenever a feature is removed from the cache. You should update your indexes, so

they become invalid in case this feature was required to successfully answer a request.

Sometimes, the whole cache changes its state and its easier to just withdraw everything.
|

In this case, this method is issued. Be sure to clear all cache information in here.

\brief
|
|
Implement this method to update the the indices, in case you need information contained by the request
|
|
to properly index. (E.g. spatial index)
|
|
Does nothing by default
|
|
|
|
\param featureRequest The feature request that was answered
|
|
\param fids The feature ids that have been returned

|
|
%Docstring
|
|
Is called, when a feature request is issued on a cached layer.
|
|
If this cache index is able to completely answer the feature request, it will return true
|
|
and set the iterator to a valid iterator over the cached features. If it is not able
|
|
it will return false.
|
|
|
|
\param featureIterator A reference to a QgsFeatureIterator. A valid featureIterator will
|
|
be assigned in case this index is able to answer the request and the return
|
|
value is true.
|
|
\param featureRequest The feature request, for which this index is queried.
|
|
|
|
:return: True, if this index holds the information to answer the request.
