setRandomAccessWindowSize

public void setRandomAccessWindowSize(int value)
Specifies how many rows can be accessed at most via getRow(). When a new node is created via createRow() and the total number of unflushed records would exeed the specified value, then the row with the lowest index value is flushed and cannot be accessed via getRow() anymore. A value of -1 indicates unlimited access. In this case all records that have not been flushed by a call to flush() are available for random access. A value of 0 is not allowed because it would flush any newly created row without having a chance to specify any cells.
