A modern programming language that makes developers happier.

kotlinlang

```package android.text.style;

import android.graphics.Paint;
import android.graphics.Canvas;
import android.text.TextPaint;

public abstract class ReplacementSpan extends MetricAffectingSpan {

    public abstract int getSize(Paint paint, CharSequence text,
                         int start, int end,
                         Paint.FontMetricsInt fm);
    public abstract void draw(Canvas canvas, CharSequence text,
                     int start, int end, float x,
                     int top, int y, int bottom, Paint paint);

    /**
     * This method does nothing, since ReplacementSpans are measured
     * explicitly instead of affecting Paint properties.
     */
    public void updateMeasureState(TextPaint p) { }

    /**
     * This method does nothing, since ReplacementSpans are drawn
     * explicitly instead of affecting Paint properties.
     */
    public void updateDrawState(TextPaint ds) { }
}```

This is the super class.
