  • public final class IdManager
extends java.lang.Object
    ID manager.

    • Method Detail

      • newVertexId

        public static java.lang.String newVertexId()
        Returns:
        a new operator ID.

      • saveVertexId

        public static void saveVertexId​(Vertex v,
                                java.lang.String id)
        Save the vertex id for the vertices that can be cloned later on. WARN: this should guarantee that the vertex is no longer used, otherwise, it would result in duplicate IDs.
        Parameters:
        v - the original vertex that is to be cloned later on (RootLoopVertex's vertex).
        id - The IDs of the identical vertices.

      • getVertexId

        public static java.lang.String getVertexId​(Vertex v)
        Used for cloning vertices. If an existing ID exists, it returns the unused ID, otherwise simply acts as the newVertexId method. WARN: the #saveVertexId method should no longer use the ID saved at that moment, in order for this method to work correctly.
        Parameters:
        v - the vertex to get the ID for.
        Returns:
        the ID for the vertex.

      • newEdgeId

        public static java.lang.String newEdgeId()
        Returns:
        a new edge ID.

      • generateResourceSpecId

        public static java.lang.String generateResourceSpecId()
        Generates the ID for a resource specification.
        Returns:
        the generated ID

      • generateDuplicatedEdgeGroupId

        public static java.lang.Integer generateDuplicatedEdgeGroupId()

      • generateMessageId

        public static java.lang.Integer generateMessageId()

      • setInDriver

        public static void setInDriver()
        Set the realm of the loaded class as REEF driver.
