Re: [Repast-interest] REpast HPC: iterate through AgentSet

[Murphy, J. T. <jtm...@an...>]

Kashif,

First, look at the 'ask' methods of the AgentSet. These iterate through the agents in the set and perform the specified function for you. See the ZombieObserver.cpp 'go()' method for an example.

If you must do it manually:

as_iterator AgentSet::begin()  - returns an iterator that represents the beginning of the agent set
as_iterator AgentSet::end() - returns an iterator that represents the end of the agent set

The data type is as_iterator; alternative versions exist for const iterators:

const_as_iterator::AgentSet::begin() const
const_as_iterator::AgentSet::end() const

Something like:


repast::relogo::AgentSet<ReLogoDemoAgent> myAgentSet;

get(myAgentSet);

repast::relogo::AgentSet<ReLogoDemoAgent>::as_iterator myIterator = myAgentSet.begin();

repast::relogo::AgentSet<ReLogoDemoAgent>::as_iterator endIter = myAgentSet.end();

while(myIterator != endIter){

  std::cout << (*myIterator)->getId()  << std::endl;

  myIterator++;

}

This will loop through the list of agents. Notice the dereferencing on myIterator when it is used in the loop; the iterator points to a pointer that must be dereferenced to use to point to the agent.

Best,
John

Hello Everyone

I have an agentset. Want to iterate through it. Need a quick tip…

Best
