Detailed Description

RAII approach to the old TopoFusion Layer data structure.

Constructor & Destructor Documentation

kjb::TopoFusion::AutoLayer::AutoLayer ( )

inline

default ctor makes a Layer ready for writing

kjb::TopoFusion::AutoLayer::AutoLayer ( const std::string &  filename )

inline

ctor loads a layer from a named file

kjb::TopoFusion::AutoLayer::~AutoLayer ( )

inline

Dtor makes sure the layer resources are released.

Member Function Documentation

void kjb::TopoFusion::AutoLayer::add_waypoint	(	const pt &	p,
		const char *	name,
		int	index
	)

A layer can hold a list of waypoints; this adds one to the list.

We CANNOT use the add waypoint method of layer.h because that assumes the waypoint is to be inserted somewhere in the global Layer structure, which we no longer use. This method emulates that one; REALLOC makes it briefer.

layer* kjb::TopoFusion::AutoLayer::get_writable_ptr ( )

inline

This is a "dangerous" method that lets you manipulate the Layer.

kjb::TopoFusion::AutoLayer::operator const layer & ( ) const

inline

this cheat lets us use an AutoLayer like a const Layer object

pt * kjb::TopoFusion::AutoLayer::set_track0points	(	unsigned	num,
		const pt *	src = 00
	)

define the first track in a layer.

Parameters

num	number of points in the track
src	array of points (pt objects) in the track

Returns

pointer to array of points where the input is stored

A Layer can hold multiple tracks. This method lets you specify the points (an array of struct pt objects) for the first track.

int kjb::TopoFusion::AutoLayer::write ( const std::string &  filename )

inline

Write a layer into a file.
