Method Detail

get

public <RowType extends Row> RowType get(int rowId)

Retrieve a row from this table. The row object itself is a cached version stored in the current process.

However, these changes will never propagate to other processes, and will be overwritten the next time the cache is updated.

Type Parameters:

RowType - type of the row to cast to before returning.

Parameters:

rowId - ID of the row to retrieve.

Returns:

locally cached copy of the row.

inc

public void inc(int rowId,
                RowUpdate rowUpdate)

Apply an update to a certain row. This update is not seen immediately at the local node, and will be seen before the staleness bound is reached.

Parameters:

rowId - ID of the row to update.

rowUpdate - update object to apply.
