Interface GraphDrawingPack.GraphDrawingInterface

public interface GraphDrawingInterface
extends Object

GraphDrawingInterface: all methods for drawing the graph on canvas. GraphCanvas has an instance of GraphDrawingInterface to implement all drawing functions. To change implementation of GraphDrawingInterface, one would have to also change the instantiation of GraphDrawingInterface in GraphCanvas.

EdgeinRect(EdgeList, double, double, double, double): return true if midpt of edge e is in the specified rectangle
VertexinRect(Vertex, double, double, double, double): return true if this vertex is in rectangle specified
addAllInRectToHE(double, double, double, double): highlight all edges within specified rectangle
addAllInRectToHV(double, double, double, double): highlight all vertices within specified rectangle
addAllInRectToHV_E(double, double, double, double): highlight all vertices and edges within specified rectangle
drawAttachedEdges(Vertex): draw all edges attached to vertex
drawE(): draw all edges in graph
drawEdge(Edge): draw Edge
drawEdge(EdgeList): draw Edge
drawEdge(Vertex, Vertex): draw Edge from v1 to v2 if it exists in the graph
drawGraph(): draw all edges and vertices in graph
drawHE(): draw all highlighted edges in graph
drawHV(): draw all highlighted vertices in graph
drawHVtrans(int, int): draw all highlighted vertices translated by specified xtrans, ytrans.
drawV(): draw all vertices in graph
drawVertex(Vertex): draw Vertex
drawvtrans(Vertex, int, int): draw vertex v translated by specified xtrans, ytrans
ptInEdge(EdgeList, double, double): return true if pt(x,y) is in active portion of the edge
ptInVertex(Vertex, double, double): return true if pt(x,y) is in vertex v
ptOnEdge(double, double): return the edge whose active portion contains point (x,y), null if no edge
ptOnVert(double, double): return vertex which contains pt(x,y), return null if pt in no vertex
