Method Details

getPrev

default Long getPrev(long rowKey)

Description copied from interface: ElementSource

Get the previous value at the rowKey. Previous values are used during an UG update cycle to process changes in data. During normal operation previous values will be identical to current values. RowKeys that were not present are undefined.

Specified by:

getPrev in interface ElementSource<Long>

Parameters:

rowKey - the location in key space to get the value from.

Returns:

the previous value at the rowKey, potentially null.
