Method Detail

nodeIterator

public static <N extends AbstractDTNode<?,?,?,N>> Iterator<N> nodeIterator(N root)

Iterator that traverses all nodes of a subtree of a given discrimination tree node.

Type Parameters:

N - node type

Parameters:

root - the root node, from which traversal should start

innerNodeIterator

public static <N extends AbstractDTNode<?,?,?,N>> Iterator<N> innerNodeIterator(N root)

Iterator that traverses all inner nodes (no leaves) of a subtree of a given discrimination tree node.

Type Parameters:

N - node type

Parameters:

root - the root node, from which traversal should start

leafIterator

public static <N extends AbstractDTNode<?,?,?,N>> Iterator<N> leafIterator(N root)

Iterator that traverses all leaves (no inner nodes) of a subtree of a given discrimination tree node.

Type Parameters:

N - node type

Parameters:

root - the root node, from which traversal should start

transformingLeafIterator

public static <N extends AbstractDTNode<?,?,?,N>,D> Iterator<D> transformingLeafIterator(N root,
                                                                                                                 Function<? super N,D> transformer)

Iterator that traverses all leaves (no inner nodes) of a subtree of a given discrimination tree node. Additionally, allows to specify a transformer that is applied to the leaf nodes

Type Parameters:

N - node type

Parameters:

root - the root node, from which traversal should start

transformer - the transformer that transforms iterated nodes
