Fill the given tile.
The provided tile might be a recycled tile, in which case it will already have objects. It is suggested to re-use these objects if possible in your use case.
| data | The data item array to fill into. Should not be accessed beyond
itemCount.
|
|---|---|
| startPosition | The start position in the list. |
| itemCount | The data item count. |
Returns tile cache size limit (in tiles).
The actual number of cached tiles will be the maximum of this value and the number of
tiles that is required to cover the range returned by
extendRangeInto(int[], int[], int).
For example, if this method returns 10, and the most
recent call to extendRangeInto(int[], int[], int) returned
{100, 179}, and the tile size is 5, then the maximum number of cached tiles will be 16.
However, if the tile size is 20, then the maximum number of cached tiles will be 10.
The default implementation returns 10.
Recycle the objects created in fillData(T[], int, int) if necessary.
| data | Array of data items. Should not be accessed beyond itemCount. |
|---|---|
| itemCount | The data item count. |
Refresh the data set and return the new data item count.
If the data is being accessed through Cursor this is where
the new cursor should be created.
