Examples of org.gephi.graph.api.Attributes

org.gephi.graph.api.Attributes
Get and set any object to this attributes class. See AttributesAPI module to look at columns definition. This interface is extended by AttributeRow that one can find in the AttributesAPI. Cast this class to AttributeRow to profit from all features.
In few words, attribute values can be get with the column index or id. @author Mathieu Bastian
