Interface Aggregator<T>

  • public interface Aggregator<T>
    The Aggregator interface acts as a service interface for different methods of aggregating attribute data for the nodes in a CyGroup. Aggregators are used to combine the attribute values of the nodes contained within a Group into a representative attribute value for the Group itself.

    Module: group-api

    To use this in your app, include the following dependency in your POM:


    Cytoscape Backwards Compatibility (SPI Interface): We expect that this interface will be implemented. Therefore to maintain backwards compatibility this interface will only be modified for major version updates.
