Detailed Description

Core definitions for the infinite (unbounded topology and depth albeit limited by memory resources) hierarchical state machine.

Declares the infinite_state structure (a node in a singly-linked ancestry chain via its super pointer) and a helper to build a forward topology (outer to inner). The enter and exit callbacks are optional (being NULL if unused) and are invoked after push (enter) and after final removal (exit) respectively.

Function Documentation

infinite_state_topology()

struct infinite_state ** infinite_state_topology	(	struct infinite_state *	state,
		int	depth,
		struct infinite_state **	topology
	)

Get the topology of the infinite state machine.

Compute a state's forward topological vector. This function fills the topology vector with the state's sub-states in "forward" order (from the outer state down to the inner). The function returns a pointer to the end of the filled vector.

This is a recursive implementation limited in depth.

Parameters

state	The current state.
depth	The current depth.
topology	The topology array to fill.

Returns

The updated topology array.
