Method Details

getLong

public long getLong(long rowKey)

Description copied from interface: ElementSource

Get the value at the rowKey as a long. RowKeys that are not present are undefined.

Specified by:

getLong in interface ElementSource<Long>

Parameters:

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

Returns:

the long at the rowKey, null values are represented by QueryConstants.NULL_LONG
