Detailed Description

Code for working with construction intervals.

Construction intervals describe built/unbuilt regions of a model and are core to the optimised construction algorithms

Definition in file pmm_interval.c.

Function Documentation

int add_bottom_interval	(	struct pmm_interval_list *	l,
		struct pmm_interval *	i
	)

Add an interval to the bottom of the interval list

Parameters

l	pointer to the interval list
i	pointer to the interval

Returns: 0 on success

Definition at line 343 of file pmm_interval.c.

int add_top_interval	(	struct pmm_interval_list *	l,
		struct pmm_interval *	i
	)

link the interval into interval list at the top/front

Parameters

l	pointer to interval list
i	pointer to interval to add to list

Returns: success always

Definition at line 311 of file pmm_interval.c.

void free_interval ( struct pmm_interval ** i )

frees an interval structure and members it contains

Parameters

i	pointer to address of the interval

Definition at line 188 of file pmm_interval.c.

void free_interval_list ( struct pmm_interval_list ** il )

frees an interval list structure and members it contains

Parameters

il	pointer to address of the interval list

Definition at line 63 of file pmm_interval.c.

struct pmm_interval* init_interval	(	int	plane,
		int	n_p,
		enum pmm_interval_type	type,
		int *	start,
		int *	end
	)

read

Initialize an interval with parameters passed.

Function maybe be used with _INFLECT and _BISECT intervals and with _POINT intervals if the start parameter is set to the point. May also be used to on initial IT_GBBP_CLIMB but not once climb_step is non-zero

Parameters

plane	plane that the interval belongs to (defunct)
n_p	number of parameters of the interval points
type	interval tyle
start	pointer to the start parameter array
end	pointer to the end parameter array

Returns: pointer to a newly allocated interval with values initialised as per the arguments passed

Definition at line 147 of file pmm_interval.c.

char* interval_type_to_string ( enum pmm_interval_type type )

map interval type to string for printing

Parameters

type	interval type

Returns: char string describing interval

Definition at line 400 of file pmm_interval.c.

int isempty_interval_list ( struct pmm_interval_list * l )

determine if interval list is empty

Parameters

l	pointer to interval list

Returns: 1 if list is empty, 0 if list is not empty

Definition at line 89 of file pmm_interval.c.

struct pmm_interval* new_interval ( )

read

Allocate and return an interval structure with default, zero parameter values

Returns: pointer to the allocated structure or NULL on failure

Definition at line 105 of file pmm_interval.c.

struct pmm_interval_list* new_interval_list ( )

read

Allocate and return an interval list structure

Returns: pointer to new interval list

Definition at line 44 of file pmm_interval.c.

void print_interval	(	const char *	output,
		struct pmm_interval *	i
	)

print interval

Parameters

output	output stream to print to
i	interval to print

Definition at line 431 of file pmm_interval.c.

void print_interval_list	(	const char *	output,
		struct pmm_interval_list *	l
	)

print interval list

Parameters

output	output stream to print to
l	interval list to print

Definition at line 374 of file pmm_interval.c.

struct pmm_interval* read_top_interval ( struct pmm_interval_list * l )

read

Definition at line 205 of file pmm_interval.c.

int remove_interval	(	struct pmm_interval_list *	l,
		struct pmm_interval *	i
	)

Removes and deletes an interval from an interval list

Parameters

l	pointer to interval list
i	pointer to the interval to remove

Returns: 1 on success

Definition at line 271 of file pmm_interval.c.

int remove_top_interval ( struct pmm_interval_list * l )

Removes and deletes the top interval on an interval list

Parameters

l	pointer to the interval list

Returns: 0 on failure, 1 on success

Definition at line 225 of file pmm_interval.c.
