I found it useful to create a simple DayCounter for my Covid19 project. I convert dates from a string in the csv data using your library and use my DayCounter to easily control days I render.
Perhaps something like day counter would be useful directly in datetime if not then left here incase useful for others, I expect you could create a date and then increment it by one day but this seemed clearer to work with a cut down format, perhaps you have similar feature already that I missed.
import datetime.DateTime;
@:structInit
class InternalDayCounter {
public var day: Int;
public var month: Int;
public var year: Int;
function new( day: Int, month: Int, year: Int ){
this.day = day;
this.month = month;
this.year = year;
}
}
@:forward
abstract DayCounter( InternalDayCounter ) from InternalDayCounter to InternalDayCounter {
public inline
function new( v: InternalDayCounter ){ this = v; }
public inline
function hasNext(){
return true;
}
public inline
function next(){
var isLeap = DateTime.isLeap( this.year );
var dayTot = DateTime.daysInMonth( this.month, isLeap );
this.day++;
if( this.day > dayTot ) {
this.day = 1;
this.month++;
if( this.month > 12 ) {
this.month = 1;
this.year++;
}
}
}
public inline
function matchDate( date: DateTime ){
return date.getDay() == this.day && date.getMonth() == this.month && date.getYear() == this.year;
}
}typical use
var dayCounter = new DayCounter({day:5,month:3,year:2020});
function renderDay(){ // every so many frames
var renderData = new Array<MyData>(); // MyData would contain date and some data values.
var j = 0;
for( d in myData ) {
if( dayCounter.matchDate( d.date ) ) renderData[ j++ ] = d;
}
plot( renderData ); // plot data to screen
dayCounter.next();
}
