Edge arrows

By default the source and the target of the edge have an arrow specified by the arrowSource and arrowTarget properties of the diagram defaults.

If is possible to customize the source and the target of the arrow by using the GraphMLEdge.getArrows() method. The resulting Arrows source and target type can be customized by the associated:

• The Arrows.setSource(short) method for the source type
• The Arrows.setTarget(short) method for the target type

Edge arrows types

The supported types for the source and target decorations are:

• The ArrowType.NONE specifies that the source or target has no decoration
• The ArrowType.STANDARD specifies that the source or target has a standard arrow:
  
  
• The ArrowType.SHORT_ARROW specifies that the source or target has a short arrow:
  
  
• The ArrowType.WHITE_DIAMOND specifies that the source or target has a white diamond:
  
  
• The ArrowType.DIAMOND specifies that the source or target has a black filled diamond:
  
  
• The ArrowType.WHITE_DELTA specifies that the source or target has a white delta:
  
  
• The ArrowType.DELTA specifies that the source or target has a black filled delta:
  
  
• The ArrowType.WHITE_CIRCLE specifies that the source or target has a white circle:
  
  
• The ArrowType.CIRCLE specifies that the source or target has a black filled circle:
  
  
• The ArrowType.CONVEX specifies that the source or target has a half circle:
  
  
• The ArrowType.SEGMENT specifies that the source or target has a small perpendicular segment:
  
  
• The ArrowType.SKEWED_DASH specifies that the source or target has a small skewed segment:
  
  
• The ArrowType.CROSS specifies that the source or target has a cross:
  
  

Example

For example, to have an edge with a standard arrow at its target:

      Arrows arrows = edge.getArrows();
      arrows.setTarget(ArrowType.STANDARD);
