Possible wrong comparsion method inside getEdgeDefinition method

[eugene-kamenev]

Just found that EdgeDefinitionsEntity.getEdgeDefinition(String collectionName) always returns null for me.
I think this is because of == string compare inside getEdgeDefinition method, it should be .equals there.
And also can you please help, how can I update edgeDefinition that already exists.

@eugene-kamenev Thanks for spotting this, will fix.

@eugene-kamenev I've uploaded a fixed version. Could you test it?

Regarding the edge definition, you should be able to use it similar to the functions described here: https://docs.arangodb.com/General-Graphs/Management.html

Is there a function missing?

@fceller I am working with GraphEntity, I can create graph structure it is not a problem. But as I see there is no methods in GraphEntity to update/modify scheme, especially edit EdgeDefinitionEntity. From the doc you mentioned above, there is no GraphEntity.editEdgeDefinitions method.

@eugene-kamenev will this method work for you?

/**

• set the edge definitions (overwrites existing edge definitions)
• @param edgeDefinitions the edge definitions to be set
  */
  public void setEdgeDefinitions(List edgeDefinitions)

@fceller No, as I tried, it will not upgrade anything. Just creates.

@eugene-kamenev need to check with my colleague.

@fceller thanks you

BTW I am developing entity mapper in groovylang, similar that i created for orientdb https://github.com/eugene-kamenev/orientdb-groovy and I am experiencing many difficulties, where can I ask questions about arangodb-java-driver and blueprints tinkerpop implementation usage?

Hello @eugene-kamenev

you have to use the function graphReplaceEdgeDefinition of the driver.

GraphEntity graph = driver.graphReplaceEdgeDefinition("myGraph", "myCollection", newEdgeDefinition);
