Member Function Documentation

◆ calcEffectiveBeamWidth()

Efix musx::dom::details::BeamAlterations::calcEffectiveBeamWidth ( ) const

Calculates the effective beam width by returning either the default width or the width override value specified by beamWidth.

Note: The beamWidth of primary beams also controls the width of secondary beams.

Returns: The effective beam width of this beam, taking into account all conditions that prefer the default width to the value in beamWidth.

◆ isActive()

bool musx::dom::details::BeamAlterations::isActive ( ) const

inline

Returns whether this beam alteration record is active. Its flattenStyle must match the value in options::BeamOptions.

Returns: True if active, otherwise false.

Member Data Documentation

◆ beamWidth

Efix musx::dom::details::BeamAlterations::beamWidth {}

The calcEffectiveBeamWidth method handles this for you.

Beam width. A value of -1 indicates to use the default beam width from options::BeamOptions.
