Method Detail

quantize

public static long quantize(long intervalInMilliseconds,
                            int resolution)

Quantizes millisecond time intervals to the specified resolution, rounding up. Examples:

• quantize(0,50) → 0
• quantize(123,10) → 130
• quantize(11,15000) → 15000
• quantize(127249,60000) → 180000

Parameters:

intervalInMilliseconds - the time interval to be quantized

resolution - the time resolution to honour, in milliseconds.

Returns:

the quantized time interval, in milliseconds with the specified resolution

quantizeToMinutes

public static long quantizeToMinutes(long intervalInMilliseconds)

Quantizes millisecond time intervals to a one minute resolution, rounding up. Examples:

• quantizeToMinutes(0) → 0
• quantizeToMinutes(123) → 60000
• quantizeToMinutes(127249) → 180000

Parameters:

intervalInMilliseconds - the time interval to be quantized

Returns:

the quantized time interval, in milliseconds with one minute resolution
