Issue

An Issue object defines a single result from a diagnostic pass within a file or workspace. For example, issues may represent parse errors, style warning, and code hints. Issues are delivered to the workspace using IssueCollection objects or an issue assistant registered with the AssistantsRegistry.

The Issue class is not subclassable.

let issue = new Issue();

issue.message = "Undefined name 'foobar'";
issue.code = "E12";
issue.severity = IssueSeverity.Error;
issue.line = 10;
issue.column = 12;

issueCollection.set(fileURI, [issue]);
