I could workaround this problem but I cannot understand it, so I am asking for some explanation (and maybe a better question title as well).
Please consider this:
public class TBGService {
// TBGObject is an abstract base class which is extended by model classes
public <T> T doGet(TBGObject model) throws TBGServiceException {
String uri = model.buildUrl(repository) + model.getObjectKey();
GetMethod method = new GetMethod(uri);
T returned = execute(method, credentials, model.getClass());
return returned;
}
}
and this:
public enum TBGTaskAttributes {
private TBGTaskAttributes(String id, String type, String label, Object... flags) {
builder = new TaskAttributeBuilder();
builder.withId(id).withLabel(label);
for (Object flag : flags) {
processFlag(flag);
}
}
public abstract String getValueFromIssue(TBGIssue issue);
public abstract void setValueInIssue(TBGIssue issue, String value);
}
when I write this code to define an enum item:
PROJECT(TaskAttribute.PRODUCT, TaskAttribute.TYPE_SINGLE_SELECT, "Project", new OptionProvider() {
@Override
public Set<Entry<String, String>> getOptions(TaskRepository repository) {
try {
List<TBGProject> list = TBGService.get(repository)
.doGet(new TBGProjects()).getProjects();
[...]
return map.entrySet();
} catch (TBGServiceException e) { [...] }
return null;
}
}) {
@Override
public String getValueFromIssue(TBGIssue issue) {
return issue.getProjectKey();
}
@Override
public void setValueInIssue(TBGIssue issue, String value) {
issue.setProjectKey(value);
}
},
[... other items ...]
I get compiler error (also eclipse auto-completion does not work):
The method getProjects() is undefined for the type Object
and if I hover the doGet method, eclipse show it as defined like:
<Object> Object TBGService.doGet(TBGObject model)
Elsewhere, hovering shows the signature correctly as:
<TBGProjects> TBGProjects TBGService.doGet(TBGObject model)
when called with parameter new TBGProjects()
.
Just changing:
List<TBGProject> list = TBGService.get(repository)
.doGet(new TBGProjects()).getProjects();
with:
TBGProjects projects = TBGService.get(repository).doGet(new TBGProjects());
List<TBGProject> = projects.getProjects();
makes it work. But what's happening here? What am I missing?
