Anylogic： How to use an agent's special connection number as a variable?

Question

I have an agent type Household, and its group households. They have a string variable identity, which will be dynamically assigned value at runtime, such as "Volunteer", "Initiator", and more.

Now I want to establish some special connections between the households. One of them is neibNet, which makes volunteers look for their nearest initiator. Then I want to read the number of neibNet connections existing on each initiator.

When I run the model, the problem is like [this](https://i.stack.imgur.com/HI8eO.png). The connections have been applied successfully, the number of neibNet connections of each Initiator has been recorded and displayed, but I cannot reference this number to calculate raisedDonation.

I have tried following methods to get the value, they all returned 0:

// test 1, told by AI that it's the overall neibNet links rather than one agent
raisedDonation = this.neibNet.getConnectionsNumber() + 1;

// test 2
raisedDonation = this.neibNet.getConnections().size() +1;

// test 3
raisedDonation = this.neibNet.size() + 1;

// test 4
raisedDonation = 1;
for (int i = 0; i < main.households.size(); i++) {
    if (main.households.get(i).identity == "Volunteer") {
        int ii = i;
        Household raised = findFirst(main.households, h -> h.householdid == ii);
        if (raised.neibNet.isConnectedTo(this) == true) raisedDonation++;
    }
}

Answer 1

I solved my problem. The function neibNet.getConnections().size() or other similar methods CAN be used to read the number of special connections linking to a specific agent. However, I read the value while forming the connections, so the function has no time to catch a value. It is my logic fault.
