musx::dom::others::SplitMeasure Class Reference

Defines the split point(s) where a measure may be divided between two systems. A measure can only split once, but Finale stores them as an array. Perhaps this was intended to support alternative break positions depending on spacing. See the warning below for the actual behavior. More...

	Constructor function.
void	integrityCheck (const std::shared_ptr< Base > &ptrToThis) override
	Override of Base::integrityCheck.

Cmper	getCmper () const
	Gets the cmper key value.
std::optional< Inci >	getInci () const
	Gets the optional array index (inci).
Cmper	getRequestedPartId () const
	If this instance was retrieved from an object pool, it contains the part ID that was used to retrieve it. If this value is different than getSourcePartId, then this instance is a copy of the pool instance.
Public Member Functions inherited from musx::dom::Base
virtual	~Base () noexcept(false)=default
	Virtual destructor for polymorphic behavior.
DocumentPtr	getDocument () const
	Gets a reference to the Document.
Cmper	getSourcePartId () const
	Gets the source partId for this instance. If an instance is fully shared with the score, the source is SCORE_PARTID. If an instance is partially shared or non shared, the source is the ID of the part that sourced it.
ShareMode	getShareMode () const
	Gets the sharing mode for this instance.
const SharedNodes &	getUnlinkedNodes () const
	Gets the unlinked nodes for this instance. (Only populated for ShareMode::Partial)
void	addUnlinkedNode (const std::string &nodeName)
	Adds a shared node for this instance.
virtual bool	requireAllFields () const
	Specifies if the parser should alert (print or throw) when an unknown xml tag is found for this class.

Static Public Member Functions
static const xml::XmlElementArray< SplitMeasure > &	xmlMappingArray ()
	Required for musx::factory::FieldPopulator.

Static Public Attributes
static constexpr std::string_view	XmlNodeName = "splitMeas"
	The XML node name for this type.

Detailed Description

Defines the split point(s) where a measure may be divided between two systems. A measure can only split once, but Finale stores them as an array. Perhaps this was intended to support alternative break positions depending on spacing. See the warning below for the actual behavior.

The array entries are Evpu offsets in Scroll View. Determining the exact split location would require converting between Scroll View Evpu positions and beat positions, which in turn depends on understanding beat charts and Finale’s layout process. A crude first approximation may be to divide the split position by Measure::width, which might yield a usable fraction of the graphical measure width to display on the previous system.

Note

This is a legacy Finale feature. It was never consistently implemented across the program, and over time it became less useful as newer features were developed without support for it. As a result, split points are rare in Finale files. The older the file, the more likely they are to appear, but even then they remain uncommon.

Warning

Early versions of Finale could create multiple split points, while recent versions allow only one.
Older files that contain multiple split points can still be opened and saved in newer Finale releases (even as recent as 27.4) without removing them. In all versions tested, however, multiple split points lead to crashes or unstable measure layouts. They are effectively unusable in any version of Finale.

This class is identified by the XML node name "splitMeas".
