Type of snapshot. Implementations are free to use whatever type makes sense for them.
Format of specified cell using 0-based row and column indexes
ItemOffsetMapping which describes sizes and offsets to start of columns
Return load status at the time the snapshot was created
On Success returns true if load has completed, false if still in progress On Err returns most recent error reported by the storage system
ItemOffsetMapping which describes sizes and offsets to start of rows
Return a snapshot to use when accessing values at a consistent point in time
Return the viewport in force (if any)
Check whether value and format are valid to set for specified cell
Ok if the value and format are valid
Set value and format of specified cell
Ok if the change was successfully applied
Set viewport of interest
Can be used by SpreadsheetData implementations to optimize data retrieval and memory usage.
Queries for cells outside the viewport may return undefined. Clients should not rely on any particular behavior
for queries outside the viewport.
Set to undefined (the default) if the client needs access to the entire spreadsheet
Subscribe to data changes
Interface used to access the data in a spreadsheet
The data exposed through the interface may change over time outside of any changes made through the interface. The caller can use the subscribe method to be notified when the data changes. When reading data, the caller must first request a snapshot using getSnapshot. All values returned by gettors are relative to a specified snapshot. The values will be consistent with each other as long as the same snapshot is used.
