  +--org.opencores.structure.Graph

public class Graph

extends java.lang.Object

Graph, that holds all nodes and nets.

Field Summary

NetGlobal[]	global all global nets
boolean	mapped specifies if graph has been mapped
java.lang.String	name graph name
java.util.Vector	nets all the nets
java.util.Vector	nodes all the nodes
NodeRoutable[][]	pos Nodes by position.
NodeSR[]	SR special resources

Constructor Summary

Graph()
Constructs new empty graph.

Method Summary

void	calcPositions() Calculates positions (.x, .y) of IndexedNodes
int	check(boolean report) checks graph for possible annomalies (unidirected lines) and can posts warnings.
void	clearNodes() Sets all segments costs to MAX_VALUE.
void	constructSegments() Constructs neighb field of all NodeRoutable nodes.
void	createFloatPositions() copies (x,y) to (fx,fy) suitable for display
void	emtpySegments() Empty all channel segments, and allocates those (on perimeter) that cannon be used.
int	repair(boolean report) repairs graph, removing floating nodes and nets
void	setRandomPositions(int X, int Y) sets random values for x from 0..X-1 and y from 0..Y-1
java.lang.String	toString() outputs graph to String
java.lang.String	toString(java.lang.String comment) outputs graph to String
void	writeBitstream(BitStreamWriter stream, boolean clear) Writes (necessary) bistream representation of this object to stream.
