Perender
Tetap teratur dengan koleksi
Simpan dan kategorikan konten berdasarkan preferensi Anda.
Renderer adalah class factory yang menggabungkan semua
komponen lain dari perender.
Class ini berisi metode untuk membuat penyedia konstanta,
info render, objek jalur, dan panel samping.
Dan ini berisi kode untuk menggabungkan semuanya saat merender blok.
Jika hanya ingin mengubah satu bagian perender yang ada (misalnya konstanta), Anda dapat membuat subclass untuk metode factory yang relevan.
