  - getLabelsAsync
```
public PgxFuture<java.util.Set<java.lang.String>> getLabelsAsync()
```
    Gets the labels
    
    Returns:
    
    the vertex labels.
    
    Throws:
    
    java.lang.IllegalStateException - if no labels exist.
  - getOutNeighbors
```
public java.util.Collection<PgxVertex<ID>> getOutNeighbors()
```
    Blocking version of getOutNeighborsAsync(). Calls getOutNeighborsAsync() and waits for returned PgxFuture to complete.
  - getInNeighbors
```
public java.util.Collection<PgxVertex<ID>> getInNeighbors()
```
    Blocking version of getInNeighborsAsync() . Calls getInNeighborsAsync() and waits for returned PgxFuture to complete.
  - getNeighbors
```
public java.util.Collection<PgxVertex<ID>> getNeighbors(Direction direction)
```
    Convenience method for getNeighbors(Direction, boolean) that keeps all duplicates.
  - getNeighbors
```
public java.util.Collection<PgxVertex<ID>> getNeighbors(Direction direction,
                                                        boolean removeDuplicates)
```
    Blocking version of getNeighborsAsync(Direction, boolean) . Calls getNeighbors(Direction, boolean) and waits for returned PgxFuture to complete.
  - getOutNeighborsAsync
```
public PgxFuture<java.util.Collection<PgxVertex<ID>>> getOutNeighborsAsync()
```
    Returns all outgoing neighbors of this vertex, i.e., all nodes this vertex has an edge to. If the graph is a multi-graph and if the vertex has multiple edges to a vertex 'A', then 'A' will appear multiple times in the result, i.e., once per edge to 'A'. This method does not guarantee any ordering in the result. This method never returns null.
  - getInNeighborsAsync
```
public PgxFuture<java.util.Collection<PgxVertex<ID>>> getInNeighborsAsync()
```
    Returns all incoming neighbors of this vertex, i.e., all vertices that have an edge to this vertex. If the graph is a multi-graph and if a vertex 'A' has multiple edges to this vertex, then 'A' will appear multiple times in the result, i.e. once per edge from 'A' to this vertex. This method does not guarantee any ordering in the result. This method never returns null.
  - getNeighborsAsync
```
public PgxFuture<java.util.Collection<PgxVertex<ID>>> getNeighborsAsync(Direction direction,
                                                                        boolean removeDuplicates)
```
    Returns all neighbors of this vertex, i.e., all vertices that are connected to this vertex.
    
    Parameters:
    
    removeDuplicates - If removeDuplicates is set to true, the resulting collection does not contain any duplicates. Otherwise, if this vertex is connected 'N' times to a vertex 'X', vertex 'X' also appears 'N' times in the results. This method does not guarantee any ordering in the result. This method never returns null.
  - getOutEdges
