Fields
placeholdersEnabled
boolean placeholdersEnabled
Defines whether placeholders are enabled, and whether the total count passed to
onResult(List, int, int) will be ignored.
requestedInitialKey
Key requestedInitialKey
Load items around this key, or at the beginning of the data set if null is
passed.
Note that this key is generally a hint, and may be ignored if you want to always load
from the beginning.
requestedLoadSize
int requestedLoadSize
Requested number of items to load.
Note that this may be larger than available data.
