                                              V lbl)

Set the node's label.

Parameters:

lbl - The node's label.

Returns:

The builder (for chaining).

getLabel

public V getLabel()

Get the label set for this node.

Returns:

The label currently set for the node builder.

addEdge

@Nonnull
public DAGNodeBuilder<V,E> addEdge(@Nonnull
                                             DAGNode<V,E> target,
                                             @Nonnull
                                             E label)

Parameters:

target - The target node.

label - The edge label.

Returns:

The builder (for chaining).

addEdge

@Nonnull
public DAGNodeBuilder<V,E> addEdge(org.apache.commons.lang3.tuple.Pair<DAGNode<V,E>,E> edge)

Add an edge.

Parameters:

edge - The target node and label for the edge.

Returns:

The builder (for chaining).

getEdges

@Nonnull
