General Info

Nodos is a very large developing platform, so we use several 3rd-party libraries and built some standards on top of them. These are important for developers that'll use C/C++ APIs of Nodos.

Flatbuffers

Our cross-process communication is based on Google's gRPC and flatbuffers. We represent nodes, pins and their data types with flatbuffers. So you should use flatbuffers to create your own data types. For this purpose, you're gonna use built-in flatbuffers types.

Built-in data types

Flatbuffers already has built-in types (such as float, uint etc), but we define the types below on top of them because they're used frequently by developers:

flatbuffers type	C++ type
float	float
double	double
ubyte	uint8_t
ushort	uint16_t
uint	uint32_t
ulong	uint64_t
byte	int8_t
short	int16_t
int	int32_t
long	int64_t
vec2	{float x,y;}
vec2d	{double x,y;}
vec2i	{int x,y;}
vec2u	{uint32_t x,y;}
vec3	{float x,y,z;}
vec3d	{double x,y,z;}
vec3i	{int x,y,z;}
vec3u	{uint32_t x,y,z;}
vec4	{float x,y,z,w;}
vec4d	{double x,y,z,w;}
vec4i	{int x,y,z,w;}
vec4u	{uint32_t x,y,z,w;}
vec4u8	{uint8_t x,y,z,w;}
void	void
StringList	{string name; vector<string> list;}

There are many more built-in types but they're mostly built on top these with some enums so we recommend you to investigate it yourself in SDK/types/Builtins.fbs file.
