    • Method Detail

      • hasTail

        boolean hasTail()
         A directed arc goes from a tail node to a head node.
 Node ids must be non-negative (>= 0).
        optional int64 tail = 1;
        Returns:
        Whether the tail field is set.

      • getTail

        long getTail()
         A directed arc goes from a tail node to a head node.
 Node ids must be non-negative (>= 0).
        optional int64 tail = 1;
        Returns:
        The tail.

      • hasHead

        boolean hasHead()
        optional int64 head = 2;
        Returns:
        Whether the head field is set.

      • getHead

        long getHead()
        optional int64 head = 2;
        Returns:
        The head.

      • hasCapacity

        boolean hasCapacity()
         Capacity of the arc. Must be non-negative (>= 0). If the capacity is zero,
 it is equivalent to not including the arc in the FlowModelProto.
        optional int64 capacity = 3 [default = 1];
        Returns:
        Whether the capacity field is set.

      • getCapacity

        long getCapacity()
         Capacity of the arc. Must be non-negative (>= 0). If the capacity is zero,
 it is equivalent to not including the arc in the FlowModelProto.
        optional int64 capacity = 3 [default = 1];
        Returns:
        The capacity.

      • hasUnitCost

        boolean hasUnitCost()
         Cost of this arc per unit of flow.
 Note that it can take any positive, negative or null value.
        optional int64 unit_cost = 4 [default = 0];
        Returns:
        Whether the unitCost field is set.

      • getUnitCost

        long getUnitCost()
         Cost of this arc per unit of flow.
 Note that it can take any positive, negative or null value.
        optional int64 unit_cost = 4 [default = 0];
        Returns:
        The unitCost.
