ProtectedboundingReadonlyFirstReadonlyLastThe symbol drawn: VexFlow's bracket, a thin line with right-angled hooks (Square) or a thin line (Line); a brace is a VexFlowInstrumentBrace.
The column left of the staves the bracket stands in: 0 beside the staves, 1 one EngravingRules.GroupBracketColumnDistance further left (a group nested in a bracketed group, or the brace of a part inside one), and so on.
ProtectedreachHow far left of the staves the symbol reaches in its column, in px: VexFlow draws a brace 14 px wide at 2 px from the staves, and a bracket's 3 px bar at 5 px; a square bracket and a line stand where the bar stands.

Returns whether this object is an instance of the class, e.g. isInstanceOfClass(GraphicalMeasure).
The class, or its name (e.g. GraphicalMeasure.name). A name is unreliable in minified builds: they rename the classes, and give different classes the same name, e.g. "a" to GraphicalMeasure and GraphicalNote.
Class that defines a instrument bracket at the beginning of a line.
