TimeSignature class

Representa a fórmula de measure.

Suporta:

  • Fórmulas simples: TimeSignature(numerator: 4, denominator: 4)
  • Fórmulas compostas: TimeSignature(numerator: 6, denominator: 8)
  • Tempo livre: TimeSignature.free()
  • Fórmulas aditivas: TimeSignature.additive(groups: [3,2,2], denominator: 8)

Constructors

TimeSignature({required int numerator, required int denominator, bool isFreeTime = false, List<AdditiveMeterGroup>? additiveGroups})
TimeSignature.additive({required List<int> groups, required int denominator})
Creates a fórmula aditiva, e.g., (3+2+2)/8.
factory
TimeSignature.free()
Creates a fórmula de tempo livre (senza misura).

Properties

additiveGroups → List<AdditiveMeterGroup>?
Grupos aditivos for fórmulas as (3+2+2)/8. When not null, overrides numerator as the beat grouping. Correspwhere a <meterSigGrp> no MEI v5.
final
denominator → int
final
hashCode → int
The hash code for this object.
no setterinherited
isAdditive → bool
Checks if is a fórmula aditiva.
no setter
isCompound → bool
Checks if is a tempo composto. Examples: 6/8, 9/8, 12/8
no setter
isFreeTime → bool
Indicates tempo livre (senza misura). When true, a fórmula is displayed as "X" or omitida. Correspwhere to the ausência de <meterSig> no MEI v5.
final
isSimple → bool
Checks if is a tempo simples. Examples: 2/4, 3/4, 4/4, 5/4, 7/8
no setter
measureValue → double
Calculates o value total permitido no measure. Fórmula: numerator × (1 / denominator). Returns infinito for tempo livre.
no setter
numerator → int
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
xmlId ↔ String?
Identificador único MEI (xml:id). Opcional; required for elementos referenciados by other via atributos de ligação of the MEI v5.
