Constructor Detail

Interval

public Interval()

Interval

public Interval(long interval)

Creates a new interval rounding.

Parameters:

interval - The interval

Method Detail

id

public byte id()

Specified by:

id in class Rounding

roundKey

public static long roundKey(long value,
                            long interval)

roundValue

public static long roundValue(long key,
                              long interval)

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;

writeTo
