Gremlin inE/outE/in/out for Vertex returns nothing... struggled for days

[Ranqi Zhu]

I am using tinkerpop 2.3, orientdb 1.4.0

Gremlin inE/outE/in/out for Vertex returns nothing... struggled for days

I build the database using blueprint Frame.

public interface NamedObject extends VertexFrame {

    @Property("name")

    public String getName();

    @Property("name")

    public void setName(final String name);

}

public interface Tile extends NamedObject {

        

    @Property("lat")

    public String getLat();

    @Property("lat")

    public void setLat(double lat);

    @Property("lat")

    public void removeLat();

    

    

    

    @Property("lon")

    public String getLon();

    @Property("lon")

    public void setLon(double lat);

    @Property("lon")

    public void removeLon();

    

    

    @Adjacency(label = "adjacent", direction=Direction.BOTH)

    public Iterable<Tile> getAjacentTiles();

    @Adjacency(label = "adjacent", direction=Direction.BOTH)

    public void setAjacentTile(final Tile adj);

    

    

    

    @Incidence(label = "adjacent")

    public Iterable<Adjacent> getAjacents();

        

    @Incidence(label = "adjacent")

    public Adjacent addAjacents(final Tile tile);

    @Incidence(label = "adjacent")

    public void removeAjacents(final Adjacent adj);

    

    

    

}

public interface Adjacent extends EdgeFrame {

@Property("weight")

public Float getWeight();

@Property("weight")

public void setWeight(float weight);

    @Domain

    public Tile getDomain();

    @Range

    public Tile getRange();

}

Hi,

you should use BP 2.4.0-SNAPSHOT with OrientDB 1.4.0-SNAPSHOT.

Hi,

It looks like you are using Frames, can you make sure you are using 2.3.1 as there was a bug that affected @Adjacency when direction was set to IN where the edge direction was always set to OUT.

<dependency>

    <groupId>com.tinkerpop</groupId>

    <artifactId>frames</artifactId>

    <version>2.3.1</version>

</dependency>

Having said that, I notice that you have Direction.BOTH on setAdjacentTile. Edges in a property graph are not bi-directional so you need to specify either Direction.IN or Direction.OUT. A get method can retrieve incoming and outgoing edges.

If you're still stuck after this then please post some more of your code and I'll try to help.

Thanks,

Bryn

Yes, I am using 2.3.1.  Thanks.

[Ranqi Zhu]

OK... Let me try. 

BTW Are there jars for 2.4? 

[Luca Garulli]

Are bundled into the graphdb/lib directory.

[Ranqi Zhu]

Thank you for the reply. 

But could you articulate where is graphdb/lib? I didn't find any in the checked out blueprint directory. 

I am new so please pardon me. 

Thank you again!

Best,

Ranqi

Where did you get Blueprints? Maven? Git? OrientDB Graph Edition?

[Ranqi Zhu]

or Could we have 2.4-snapshot in Maven? Thanks!

Hi,

About 1 hour ago I deployed the 2.4.0-SNAPSHOT to SonaType SNAPSHOT repo.

Marko.

[Ranqi Zhu]

Downloaded jar from the Central repo. 

But I just got Marko's 2.4.0-SNAPSHOT at SonaType repo though.

However, now I can't even init a Orientgraph. It dies at

        m_dbg = new OrientGraph("remote:localhost/nycTpFrames1k", "admin", "admin");

Exception in thread "main" java.lang.NoSuchFieldError: CUSTOM

Got it! Thank you Marko!!
