The Cmper for a MeasureExprAssign is the Cmper of the Measure to which it is attached.

Member Enumeration Documentation

Member Function Documentation

◆ calcAppliesToLayer()

bool musx::dom::others::MeasureExprAssign::calcAppliesToLayer ( LayerIndex layerIndex ) const

Calculates if this assignment applies to the specified layer.

Parameters

layerIndex The 0-based LayerIndex to check (0..3).

◆ calcAssignedStaffId()

StaffCmper musx::dom::others::MeasureExprAssign::calcAssignedStaffId ( bool forPageView = true ) const

Calculates the effective staffId for the assignment, returning top or bottom staff if appropriate.

Parameters

forPageView Return the top/bottom staff in page view (when appropriate). If the staff does not appear in page view, the function falls back to scroll view.

Returns: Either the actual staff or the top or bottom staff in page view or scroll view in the current requested part.

◆ calcAssociatedEntry()

EntryInfoPtr musx::dom::others::MeasureExprAssign::calcAssociatedEntry ( ) const

Calculates the entry associated with the the measure expression. This is the entry that Finale uses for auto-positioning. The entry must match the elapsed position, voice2 setting, and the layer (when specified). No fuzzy search is performed.

Returns: The entry if the assignment's target entry exists; otherwise nullptr.

◆ calcIsPartOfStaffListAssignment()

bool musx::dom::others::MeasureExprAssign::calcIsPartOfStaffListAssignment ( ) const

Calculates if this assignment participates in a staff-list-based assignment group.

This checks the assignment-level grouping fields first, then falls back to the assigned expression category when the category uses staff lists. This works for both text and shape expressions.

◆ createCurrentStaff()

MusxInstance< StaffComposite > musx::dom::others::MeasureExprAssign::createCurrentStaff ( bool forPageView = true ) const

Creates the current staff for this assignment.

Parameters

forPageView If this value is true, calculates the current staff in page view, otherwise is scroll view.

◆ createStaffListSet()

CategoryStaffListSet musx::dom::others::MeasureExprAssign::createStaffListSet ( ) const

Create a StaffListSet for the given instance. This can be used to interrogate whether a staff appears in the staff set.

Returns: The created staff list set. If staffList is zero, the function falls back to the expression category's staff list when that category uses staff lists. Otherwise it will never find any staves.

◆ getMarkingCategory()

MusxInstance< MarkingCategory > musx::dom::others::MeasureExprAssign::getMarkingCategory ( ) const

Gets the marking category for the assigned text or shape expression.

Returns: The marking category or nullptr if the definition or its category cannot be resolved.

◆ getShapeExpression()

MusxInstance< ShapeExpressionDef > musx::dom::others::MeasureExprAssign::getShapeExpression ( ) const

Gets the assigned shape expression.

Returns: The shape expression or nullptr if this assignment is for a text expression or shapeExprId not found.

◆ getTextExpression()

MusxInstance< TextExpressionDef > musx::dom::others::MeasureExprAssign::getTextExpression ( ) const

Gets the assigned text expression.

Returns: The text expression or nullptr if this assignment is for a shape expression or textExprId not found.

◆ integrityCheck()

void musx::dom::others::MeasureExprAssign::integrityCheck ( const std::shared_ptr< EnigmaBase > & ptrToThis )

inlineoverridevirtual

Performs a final consistency check after population.

Reimplemented from musx::dom::EnigmaBase.

Member Data Documentation

◆ staffList

Cmper musx::dom::others::MeasureExprAssign::staffList {}

The cmper of the marking category staff list that is controlling this assignment (if any). There will be a separate MeasureExprAssign instance for every staff in the staff list.

◆ voice2

bool musx::dom::others::MeasureExprAssign::voice2 {}

If true, positioning is relative to a voice2 entry. This setting is a legacy setting that Finale sets when it upgrades a pre-Finale 2009 file. It is not available in the UI. However, an expression does not recognize entry positioning for a voice2 entry unless this value is true. And if it is true, entry-positioning ignores voice 1 entries. (xml node is <v2>)
