package com.sample.app;

import com.arangodb.ArangoCollection;
import com.arangodb.ArangoDB;
import com.arangodb.ArangoDatabase;
import com.arangodb.entity.CollectionEntity;
import com.arangodb.entity.CollectionStatus;
import com.arangodb.entity.CollectionType;
import com.arangodb.mapping.ArangoJack;

public class CollectionInfoDemo {
    private static final String USER_NAME = "root";
    private static final String PASSWORD = "tiger";
    private static final String HOST = "127.0.0.1";
    private static final int PORT = 8529;

    public static void main(String args[]) {
        // Get an ArangoDB instance
        ArangoDB arangoDB = new ArangoDB.Builder().user(USER_NAME).password(PASSWORD).host(HOST, PORT)
                .serializer(new ArangoJack()).build();

        String databaseName = "testdb";
        arangoDB.createDatabase(databaseName);

        ArangoDatabase arangoDatabase = arangoDB.db(databaseName);

        String collectionName = "users";

        arangoDatabase.createCollection(collectionName);

        ArangoCollection arangoCollection = arangoDatabase.collection(collectionName);
        CollectionEntity collectionEntity = arangoCollection.getInfo();

        String collectionId = collectionEntity.getId();
        Boolean isSystemCollection = collectionEntity.getIsSystem();
        collectionName = collectionEntity.getName();
        CollectionStatus collectionStatus = collectionEntity.getStatus();
        CollectionType collectionType = collectionEntity.getType();

        System.out.println("Collection details ");
        System.out.println("collectionId : " + collectionId);
        System.out.println("isSystemCollection : " + isSystemCollection);
        System.out.println("collectionName : " + collectionName);
        System.out.println("collectionStatus : " + collectionStatus);
        System.out.println("collectionType : " + collectionType);

        // Dropping the collection and database
        arangoCollection.drop();
        arangoDatabase.drop();
    }
}

Output

collectionId : 51904
isSystemCollection : false
