Checks whether a function declaration has parameters that are top level const. const values in declarations do not affect the signature of a function, so they should not be put there.

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

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.

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

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.
|

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.
