Methods

between() : string|null
call() : string
composite() : string: Comparisons bind tighter than AND/OR, so only a nested AND/OR is parenthesized.
list() : string: Cut after a few values, so a long list never makes an unbounded line.
of() : string
operand() : string: An operator inside another operator is parenthesized; a reference, a value or a call reads unambiguously as is.
operator() : string|null: Null for a function the explain has no wording for.
pair() : string
range() : string
value() : string
