Constructor Details

GraphEdge

public GraphEdge(GraphNode fromNode,
 GraphNode toNode)

Constructor defining a directional edge, from one node to another. Depending on the object type of either node, this will also set its VisualStyle object type enum.

Parameters:

fromNode -

toNode -

GraphEdge

public GraphEdge(GraphNode fromNode,
 GraphNode toNode,
 StyleObjectType styleObjecType)

Constructor defining a directional edge, when the type is already known. Useful for complement factors, since the general calculations can't distinguish left and right

Parameters:

fromNode -

toNode -

styleObjecType -

Method Details

equals

public boolean equals(Object obj)

Compares two edges and considers them equal if the target and destination nodes are the same

Overrides:

equals in class Object

Parameters:

obj - GraphEdge to compare

Returns:

hashCode

public int hashCode()

Computes the hash code based on the origin and destination nodes

Overrides:

hashCode in class Object

Returns:

the hash code

getFromNode

public GraphNode getFromNode()

gets the origin node for the edge

Returns:

origin node

getToNode

public GraphNode getToNode()

gets the destination node for the edge

Returns:

destination node

getStyleObjectType

public StyleObjectType getStyleObjectType()

gets the VisualStyle object type enum

Returns:

VisualStyle object type
