Imports

java.util.ArrayList, .LinkedHashMap, .List, .Map, .StringJoiner, java.util.function.Function, java.util.regex.Pattern, jdk.jfr.EventType, jdk.jfr.consumer.RecordedEvent, jdk.jfr.internal.util.Utils, .Matcher, .SpellChecker, jdk.jfr.internal.query.FilteredType.Filter, .Query.Condition, .Query.Expression, .Query.Formatter, .Query.Grouper, .Query.OrderElement, .Query.Source

Purpose of this class is to take a query and all available event types and check that the query is valid, for example, to see if all fields and types referenced in the query exists. The end result is a list of fields suitable for grouping, sorting and rendering operations later.
