onResult(List, int, int) will be ignored.
requestedLoadSize
int requestedLoadSize
Requested number of items to load.
Note that this may be larger than available data.
requestedStartPosition
int requestedStartPosition
Initial load position requested.
Note that this may not be within the bounds of your data set, it may need to be adjusted
before you execute your load.
