Java Code Examples for java.time.LocalTime#MIDNIGHT

/**
 * generatePotentialMenuTimes, This will generate a list of menu times for populating the combo
 * box menu, using a TimePickerSettings.TimeIncrement value. The menu times will always start at
 * Midnight, and increase according to the increment until the last time before 11:59pm.
 *
 * Note: This function can be called before or after setting an optional veto policy. Vetoed
 * times will never be added to the time picker menu, regardless of whether they are generated
 * by this function.
 *
 * Example usage: generatePotentialMenuTimes(TimeIncrement.FifteenMinutes);
 *
 * Number of entries: If no veto policy has been created, the number of entries in the drop down
 * menu would be determined by the size of the increment as follows; FiveMinutes has 288
 * entries. TenMinutes has 144 entries. FifteenMinutes has 96 entries. TwentyMinutes has 72
 * entries. ThirtyMinutes has 48 entries. OneHour has 24 entries.
