    • getPrev

      default Character 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<Character>
      Parameters:
      rowKey - the location in key space to get the value from.
      Returns:
      the previous value at the rowKey, potentially null.

    • getPrevBoolean

      default Boolean getPrevBoolean(long rowKey)
      Description copied from interface: ElementSource
      Get the previous value at the rowKey as a Boolean. See ElementSource.getPrev(long) for more details. RowKeys that were not present are undefined.
      Specified by:
      getPrevBoolean in interface ElementSource<Character>
      Parameters:
      rowKey - the location in key space to get the previous value from.
      Returns:
      the previous boolean at the rowKey, potentially null.

    • getPrevByte

      default byte getPrevByte(long rowKey)
      Description copied from interface: ElementSource
      Get the previous value at the rowKey as a byte. See ElementSource.getPrev(long) for more details. RowKeys that were not present are undefined.
      Specified by:
      getPrevByte in interface ElementSource<Character>
      Parameters:
      rowKey - the location in key space to get the previous value from.
      Returns:
      the previous boolean at the rowKey, null values are represented by QueryConstants.NULL_BYTE

    • getPrevDouble

      default double getPrevDouble(long rowKey)
      Description copied from interface: ElementSource
      Get the previous value at the rowKey as a double. See ElementSource.getPrev(long) for more details. RowKeys that were not present are undefined.
      Specified by:
      getPrevDouble in interface ElementSource<Character>
      Parameters:
      rowKey - the location in key space to get the previous value from.
      Returns:
      the previous double at the rowKey, null values are represented by QueryConstants.NULL_DOUBLE

    • getPrevFloat

      default float getPrevFloat(long rowKey)
      Description copied from interface: ElementSource
      Get the previous value at the rowKey as a float. See ElementSource.getPrev(long) for more details. RowKeys that were not present are undefined.
