Detailed Description

This class is an interface for MEI beam elements (beam, beamSpan).

It stores stem drawing values. It is also an ObjectListInterface.

Member Function Documentation

◆ GetAdditionalBeamCount()

virtual std::pair<int, int> vrv::BeamDrawingInterface::GetAdditionalBeamCount ( ) const

inlinevirtual

Helper to find number of additional beams.

Return { additional beams above main beam, additional beams below }

Reimplemented in vrv::Beam, and vrv::FTrem.

◆ GetPosition()

int vrv::BeamDrawingInterface::GetPosition ( const LayerElement * element ) const

protected

Return the position of the element in the beam.

For notes, lookup the position of the parent chord.

The documentation for this class was generated from the following file:
