Constructor Detail

MillisRounder

public MillisRounder(long millis,
                     boolean roundStart,
                     boolean roundEnd,
                     boolean keepSameLength)
Creates a MillisRounder.

Parameters:
millis - The number of millis to round to. For instance 1000 would round to even seconds.
roundStart - If the start date/time should be rounded.
roundEnd - If the end date/time should be rounded.
keepSameLength - If not both of roundStart and roundEnd of a MutableDateRange are rounded and keepSameLength is true, the one of roundStart or roundEnd time that is not rounded will be set so that the spanned time in the range will remain the same.
If this is true, the result is actually a rounded move of the range rather than a resize.
keepSameLength can't be true if both roundStart and roundEnd is true.
