| Class | public class SpanningTree |
| Inheritance | SpanningTree  TreeBuilder |
| Implements | IOperator |
This class can annotate graph edges as belonging to the spanning tree
(done if the annotateEdges property is true), and can
construct a Tree instance (done if the
buildTree property is true). Generated Tree
instances are stored in the tree property. Generated trees
contain the original nodes and edges in the input graph, and any
previous parent or child links for input nodes will be cleared and
overwritten.
This class extends the TreeBuilder class to also function as an operator that can be added to a visualization's operator list.

calculation.
