SkipSpan determines if a span should be processed. True is returned when a span should be skipped. False is returned when a span should not be skipped. The logic determining if a span should be processed is set in the attribute configuration with the include and exclude settings. Include properties are checked before exclude settings are checked.
TODO: Modify Matcher to invoke both the include and exclude properties so calling processors will always have the same logic. Matcher is an interface that allows matching a span against a configuration of a match.
