FlatBuffers使用总结(3)

1、IDL测试文件

// Example IDL file for our monster's schema.
namespace MyGame.Sample;
enum Color:byte { Red = 0, Green, Blue = 2 }
union Equipment { Weapon } // Optionally add more tables.
struct Vec3 {
  x:float;
  y:float;
  z:float;
}
table Monster {
  pos:Vec3; // Struct.
  mana:short = 150;
  hp:short = 100;
  name:string;
  friendly:bool = false (deprecated);
  inventory:[ubyte];  // Vector of scalars.
  color:Color = Blue; // Enum.
  weapons:[Weapon];   // Vector of tables.
  equipped:Equipment; // Union.
  path:[Vec3];        // Vector of structs.
}
table Weapon {
  name:string;
  damage:short;
}
root_type Monster;

 

2、生成桩文件

利用flatc.exe生成IDL对应的桩代码，命令格式为

flatc [ GENERATOR OPTIONS ] [ -o PATH ] [ -I PATH ] [ -S ] FILES...  [ -- FILES...]

flatc --cpp monster.fbs
