question: private static Pair < DiagnosticKind , Boolean > parseCategoryString ( String category ) { final String fixable = "fixable-" ; final boolean isFixable = category . startsWith ( fixable ) ; if ( isFixable ) { category = category . substring ( fixable . length ( ) ) ; } DiagnosticKind categoryEnum = DiagnosticKind . fromParseString ( category ) ; return Pair . of ( categoryEnum , isFixable ) ; }
target:  Given a category string that may be prepended with "fixable-", return the category enum that corresponds with the category and whether or not it is a isFixable error
