SkPath vs SkPathBuilder

[L2000]

Hi
    I would like to know the difference between skpath and skpathbuilder. When i tried using both in my project, I found skpath showing variable and larger time for drawing compared to SkPathBuilder. I have measured time for the following snippet code :

SkPath : (time taken ~ 400 - 600 micro secs)

SkPath path;

int y = 0;

for ( int i = 0 ; i<= 50 ; i++){

    int x = 0;

    for(int j = 0; j<=50 ; j++){

         path.moveTo(x, y);

         path.lineTo(x+colWidth, y);

         path.lineTo(x+colWidth, y+rowHt);

         x +=5;

       }

      y += 5;

}

canvas->drawPath(path, paint);

SkPathBuilder: ( time taken ~ 150 - 300 micro sec)

SkPathBuilder builder;

int y = 0;

for ( int i = 0 ; i<= 50 ; i++){

    int x = 0;

    for(int j = 0; j<=50 ; j++){

         builder.moveTo({x,y});

         builder.lineTo({x+colWidth, y});

         builder.lineTo({x+colWidth, y+rowHt});

         x +=5;

       }

      y += 5;

}

canvas->drawPath(builder.detach(), paint);

I assume, that is the way a builder should work. You add your drawing commands and at the end all calculations are done. When you use a normal path directly, these calculations had to be done each time you change something on the path.
