How to get voters lists from all linked issues

Question

I am trying to create a JIRA plugin that does the following:

1. For each issue, takes all linked issues which are linked by "duplicates" or "is duplicated by" (or other predefined link types).
2. For each such issue, get a list (not necessarily a List object) of the voters on that issue.

My problem is that the javadoc has little to no information. Following a tutorial, I currently have:

public class VotersCount extends AbstractJiraContextProvider {

    @Override
    public Map<String, Integer> getContextMap(User user, JiraHelper jiraHelper) {

        Map<String, Integer> contextMap = new HashMap<>();
        Issue currentIssue = (Issue) jiraHelper.getContextParams().get("issue");
//      Issue[] linkedIssues = currentIssue.getLinkedIssuesBy(...); //Step 1 mock code
//      Voter[] voters = linkedissues[3].getVoters(); //Step 2 mock code
        int count = voters.length; //Pretend there is some calculation here
        contextMap.put("votersCount", count);
        return contextMap;
    }
}

(and I use votersCount in the .vm file.)

However, I see no explanation in the javadocs for AbstractJiraContextProvider and getContextMap so I'm not even sure if it's the right approach.

In my own research I found the class ViewVoters which has the method Collection<UserBean> getVoters() , which is something I can work with, but I don't know how to obtain or construct such an object in a way which will interact with a given issue.

I am looking for a working code to replace my 2 lines of mock code.

Answer 1

1) Use one of the methods from IssueLinkService. Maybe getIssueLinks

2) issueVoterAccessor.getVoterUserkeys

Instances of IssueLinkService and IssueVoterAccessor should be injected as parameters to constructor of your VotersCount.

Answer 2

I solved it by using the following:

1. To get issues linked to Issue issue by specified link types:

    LinkCollection linkCollection = ComponentAccessor.getIssueLinkManager().getLinkCollectionOverrideSecurity(issue); Set<IssueLinkType> linkTypes = linkCollection.getLinkTypes(); // Perform operations on the set to get the issues you want. for (IssueLinkType linkType : linkTypes) { List<Issue> l1 = linkCollection.getOutwardIssues(linkType.getName()); List<Issue> l2 = linkCollection.getInwardIssues(linkType.getName()); } 

2. To get all the voters on Issue issue :

    ComponentAccessor.getVoteManager().getVoterUserkeys(issue); 

I was later shown that one can extend CalculatedCFType and override getValueFromIssue which hands you the current issue as a parameter instead of the using

Issue currentIssue = (Issue) jiraHelper.getContextParams().get("issue");
