AbstractProtecteddynamicProtectedgraphicalProtectedgraphicalProtectedmusicProtectedrulesProtectedskyLazy rendering: cache of computed sky/bottom lines, keyed per staff line by its system's measure range + staff index. A growing-prefix batch re-runs the (expensive) skyline pass over the whole prefix; this lets stable interior systems reuse the lines computed in an earlier batch instead of re-measuring them. Only used when EngravingRules.LazyConsistentGraphic; cleared per lazy session.
ProtectedstaffProtectedstaffProtectedstaffProtectedstaffStaticstafflineStaticsymbolProtected StatictextStatictransposeProtectedleadStaticTextProtectedcalcThe main method for the Calculator.
ProtectedcalculateReturns the highest (minimum) skyline and lowest (maximum) bottom line value under the chord symbols of the given staff entries, where they are drawn (see calculateChordSymbolsXPositions(), called before), to place them at one y position.
The staff entries whose chord symbols to align, e.g. of a staffline or measure (ChordSymbolYAlignmentScope).
The sky and bottom line calculator of the staffline of the staff entries.
The minimum skyline value under chord symbols placed above, and the maximum bottom line value under chord symbols placed below (Number.MAX_SAFE_INTEGER and Number.MIN_SAFE_INTEGER if there are none).
ProtectedcalculateProtectedcalculateSets the x positions of the chord symbols of a measure (relative to their parent bounding boxes), before their y positions: a chord symbol not over a note goes from its staff entry (which has no x position without notes) to the measure, at an x proportional to its timestamp in the measure, and a chord symbol over a whole measure rest after the begin instructions.
The measure whose chord symbols to position.
The index of the measure in its staffline, to find the measures of the other staves in musicSystem.
The system of the measure: chord symbols without a staff entry x position take the x position of a staff entry with the same timestamp in the other staves.

ProtectedcalculateThis method calculates the RelativePosition of a single GraphicalContinuousDynamic.
Graphical continous dynamic to be calculated

ProtectedcalculateThis method calculates the RelativePosition of a single GraphicalInstantaneousDynamicExpression.

ProtectedcalculateThis method calculates the RelativePosition of a single verbal GraphicalContinuousDynamic.

ProtectedcalculateProtectedcalculatecalculates the dashes of lyric words and the extending underscore lines of syllables sung on more than one note.
ProtectedcalculateProtectedcalculateIterate through all Measures and calculates the MeasureNumberLabels.
ProtectedcalculateCalculates the x layout of the staff entries within the staff measures belonging to one source measure. All staff entries are x-aligned throughout all the measures.
The minimum required x width of the source measure

ProtectedcheckProtectedclearDelete all Objects that must be recalculated. If graphicalMusicSheet.reCalculate has been called, then this method will be called to reset or remove all flexible graphical music symbols (e.g. Ornaments, Lyrics, Slurs) graphicalMusicSheet will have MusicPages, they will have MusicSystems etc...

ProtectedinitCalled for every source measure when generating the list of staff measures for it.
ProtectedisWhether two metronome marks print the same: note equations by their notes rather than their playback tempo, other marks by beat unit and bpm.

ProtectedlayoutDo layout on staff measures which only consist of a full rest.
ProtectedlayoutProtectedlayoutProtectedlayoutCalculate a single GraphicalRepetition.
ProtectedlayoutProtectedlayoutProtectedlayoutProtectedmaxProtectedoptimizeBuild the 2D [[GraphicalMeasure]] list needed for the [[MusicSheetCalculator]]. Internally it creates [[GraphicalMeasure]]s, [[GraphicalStaffEntry]]'s and [[GraphicalNote]]s.
ProtectedreserveReserves skyline space for measure-repeat counts.
ProtectedresetProtectedskyStable per-staff-line key for the lazy sky/bottom-line cache: the system's measure range pins the system (systems partition the measures), the staff index picks the line within it. Returns undefined for a staff line with no usable measures (so it is never cached/reused).
