Constructor Detail

PrePostRounding

public PrePostRounding(Rounding intervalRounding,
                       long preOffset,
                       long postOffset)

Method Detail

id

public byte id()

Specified by:

id in class Rounding

roundKey

public long roundKey(long value)

Description copied from class: Rounding

Given a value, compute a key that uniquely identifies the rounded value although it is not necessarily equal to the rounding value itself.

Specified by:

roundKey in class Rounding

valueForKey

public long valueForKey(long key)

Description copied from class: Rounding

Compute the rounded value given the key that identifies it.

Specified by:

valueForKey in class Rounding

nextRoundingValue

public long nextRoundingValue(long value)

Description copied from class: Rounding

Given the rounded value (which was potentially generated by Rounding.round(long), returns the next rounding value. For example, with interval based rounding, if the interval is 3, nextRoundValue(6) = 9 .

Specified by:

nextRoundingValue in class Rounding

Parameters:

value - The current rounding value

Returns:

The next rounding value;
