@FunctionalInterface
public interface BSPTreeVisitor<P extends Point<P>,N extends BSPTree.Node<P,N>>
```
Interface for visiting the nodes in a BSPTree or BSPSubtree.

Nested Class Summary

Nested Classes
Modifier and Type	Interface	Description
`static class`	`BSPTreeVisitor.ClosestFirstVisitor<P extends Point<P>,N extends BSPTree.Node<P,N>>`	`BSPTreeVisitor` base class that orders tree nodes so that nodes closest to the target point are visited first.
`static class`	`BSPTreeVisitor.FarthestFirstVisitor<P extends Point<P>,N extends BSPTree.Node<P,N>>`	`BSPTreeVisitor` base class that orders tree nodes so that nodes farthest from the target point are traversed first.
`static class`	`BSPTreeVisitor.Order`	Enum used to specify the order in which visitors should visit the nodes in the tree.
`static class`	`BSPTreeVisitor.Result`	Enum representing the result of a BSP tree node visit operation.
`static class`	`BSPTreeVisitor.TargetPointVisitor<P extends Point<P>,N extends BSPTree.Node<P,N>>`	Abstract class for `BSPTreeVisitor` implementations that base their visit ordering on a target point.

Method Summary

All Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method	Description
`BSPTreeVisitor.Result`	`visit(N node)`	Visit a node in a BSP tree.
`default BSPTreeVisitor.Order`	`visitOrder(N internalNode)`	Determine the visit order for the given internal node.

- Method Detail
  - visit
```
BSPTreeVisitor.Result visit(N node)
```
    Visit a node in a BSP tree. This method is called for both internal nodes and leaf nodes.
    
    Parameters:
    
    node - the node being visited
    
    Returns:
    
    the result of the visit operation
  - visitOrder
```
default BSPTreeVisitor.Order visitOrder(N internalNode)
```
    Determine the visit order for the given internal node. This is called for each internal node before visit(BSPTree.Node) is called. Returning null or BSPTreeVisitor.Order.NONEfrom this method skips the subtree rooted at the given node. This method is not called on leaf nodes.
    
    Parameters:
    
    internalNode - the internal node to determine the visit order for
    
    Returns:
    
    the order that the subtree rooted at the given node should be visited
