Constructor Detail
GraphDistanceFilter
public GraphDistanceFilter(String group)(Code)
Create a new GraphDistanceFilter that processes the given data group and uses a graph distance of 1. By default, the prefuse.Visualization.FOCUS_ITEMS group will be used as the source nodes from which to measure the distance.
Parameters:
  group - the group to process. This group should resolve to aGraph instance, otherwise exceptions will be thrown when thisAction is run.



GraphDistanceFilter
public GraphDistanceFilter(String group, int distance)(Code)
Create a new GraphDistanceFilter that processes the given data group and uses the given graph distance. By default, the prefuse.Visualization.FOCUS_ITEMS group will be used as the source nodes from which to measure the distance.
Parameters:
  group - the group to process. This group should resolve to aGraph instance, otherwise exceptions will be thrown when thisAction is run.
Parameters:
  distance - the graph distance within which items will bevisible.



GraphDistanceFilter
public GraphDistanceFilter(String group, String sources, int distance)(Code)
Create a new GraphDistanceFilter that processes the given data group and uses the given graph distance.
Parameters:
  group - the group to process. This group should resolve to aGraph instance, otherwise exceptions will be thrown when thisAction is run.
Parameters:
  sources - the group to use as source nodes for measuringgraph distance.
Parameters:
  distance - the graph distance within which items will bevisible.




Method Detail
getDistance
public int getDistance()(Code)
Return the graph distance threshold used by this filter. the graph distance threshold



getSources
public String getSources()(Code)
Get the name of the group to use as source nodes for measuring graph distance. These form the roots from which the graph distance is measured. the source data group



run
public void run(double frac)(Code)

See Also:   prefuse.action.GroupAction.run(double)



setDistance
public void setDistance(int distance)(Code)
Set the graph distance threshold used by this filter.
Parameters:
  distance - the graph distance threshold to use



setSources
public void setSources(String sources)(Code)
Set the name of the group to use as source nodes for measuring graph distance. These form the roots from which the graph distance is measured.
Parameters:
  sources - the source data group
