The Vertex.java Java example source code

package org.deeplearning4j.models.sequencevectors.graph.primitives;

import lombok.AllArgsConstructor;
import lombok.Getter;
import lombok.Setter;
import org.deeplearning4j.models.sequencevectors.sequence.SequenceElement;

/** Vertex in a graph
 * @param <T> the type of the value/object associated with the vertex
public class Vertex<T extends SequenceElement> {

    private final int idx;
    @Getter @Setter private T value;

    public int vertexID() {
        return idx;

    public String toString() {
        return "vertex(" + idx + "," + (value!=null ? value : "") + ")";

    public boolean equals(Object o) {
        if (!(o instanceof Vertex)) return false;
        Vertex<?> v = (Vertex) o;
        if (idx != v.idx) return false;
        if ((value == null && v.value != null) || (value != null && v.value == null)) return false;
        return value == null || value.equals(v.value);
