Engine execution question

[Visser, Dale]

I am writing an analyzer, and I have written a piece of code like this, where 'dependency' is a new Dependency instance I have created inside the Analyzer, and 'engine' is the Engine instance passed into analyzeFileType(Dependency, Engine):

// copy, alter and set in case some other thread is iterating over
final List<Dependency> dependencies = new ArrayList<Dependency>(engine.getDependencies());
dependencies.add(dependency);
engine.setDependencies(dependencies);

Am I being too cautious? Is the execution of the various Analyzers by the Engine single-threaded, or effectively so?

Best regards,
Dale Visser

Due to how some of the analyzers work they will only be executed in a single-threaded order. Some of the analyzers may spin up threads to do their individual work faster, but individual analyzers will not execute at the same time as other analyzers. So yes, the code is a little too cautious.
