Property key is the name of property we want to filter.Only people with at least 5 years of experience and those which have driver licence types A, B and C will be included. For example previous dialog can be used when we want to find all people working on project Gephi with maximum age 30 years. We can customize the rules responsible for returning nodes by defining filtering expressions. Whole graph import dialog is designed for importing whole graph. Importing process consist of 2 approaches: Every valid class file will have Neo4j picture and after selecting a valid debug file, Target and Visualization options will be automatically filled based on data from selected class file. This simply means they have to implement required interface and have public nonparam constructor. The open dialog for debugging accepts only Java class files that can be used for debugging process. User is able to open only valid Neo4j directories in the process of importing. I defined valid Neo4j database directory structure and every valid directory now includes picture of Neo4j in the open dialog. ![]() The open dialog for importing accepts only valid Neo4j database directories. In fact during the importing process, graph representation of Neo4j graph is created in Gephi, but all values are not stored directly, but they are queried using delegating mechanism.Īnother minor tasks were to customize the open dialogs used for importing local Neo4j database and debugging the imported database. This mechanism is responsible for getting values from storing engine (Neo4j) as well as manipulation with data. The most interesting thing is adding “Delegating mechanism”. There were also some changes under the hood which are not visible to end user, but must be defined and implemented. This mismatch was solved by adding new “List” types into Gephi, so now every type in Neo4j has its appropriate type in Gephi. There was also a mismatch between types supported in Neo4j and these supported by Gephi. In fact, both graph models are different so the first task was to make mapping between Neo4j graph items and Gephi graph items and vice versa. This means the ability to transform the Neo4j graph into Gephi graph. The main idea of my project is to add support for Neo4j in Gephi.
