Example 1
Source File: DetachedVertexProperty.java    From tinkerpop with Apache License 2.0 6 votes vote down vote up 
protected DetachedVertexProperty(final VertexProperty<V> vertexProperty, final boolean withProperties) {
    super(vertexProperty);
    this.value = vertexProperty.value();
    this.vertex = DetachedFactory.detach(vertexProperty.element(), false);

    // only serialize properties if requested, the graph supports it and there are meta properties present.
    // this prevents unnecessary object creation of a new HashMap which will just be empty.  it will use
    // Collections.emptyMap() by default
    if (withProperties && vertexProperty.graph().features().vertex().supportsMetaProperties()) {
        final Iterator<Property<Object>> propertyIterator = vertexProperty.properties();
        if (propertyIterator.hasNext()) {
            this.properties = new HashMap<>();
            propertyIterator.forEachRemaining(property -> this.properties.put(property.key(), Collections.singletonList(DetachedFactory.detach(property))));
