Constructor & Destructor Documentation

◆ NativeFunction()

littlefoot::NativeFunction::NativeFunction	(	const char *	nameAndArgumentTypes,
		ImplementationFunction	fn
	)

Creates a NativeFunction from its signature and an implementation function.

The format of nameAndArgumentTypes is "name/[return type][arg1][arg2..]" So for example "int foobar (float, bool)" would be "foobar/ifb"

References numArgs, and returnType.

◆ createID()

static FunctionID littlefoot::NativeFunction::createID ( const char * nameAndArgTypes )

static

Converts a function signature to its hashed ID.

◆ nameAndArguments

const char* littlefoot::NativeFunction::nameAndArguments

This signature must have the form "name/[return type][arg1][arg2..]".

◆ function

ImplementationFunction littlefoot::NativeFunction::function

A static function that will be called.

◆ functionID

FunctionID littlefoot::NativeFunction::functionID

The ID is a hash of the name + arguments, but not the return type.

◆ returnType

Type littlefoot::NativeFunction::returnType

The function's return type.

◆ numArgs

uint8 littlefoot::NativeFunction::numArgs

The number of arguments that the function takes.
