Constructor & Destructor Documentation

BDSBeamline::BDSBeamline ( )

Default constructor. Beamline started at 0,0,0 with beamline built along the z axis.

Definition at line 20 of file BDSBeamline.cc.

References maximumExtentNegative, maximumExtentPositive, previousReferencePositionEnd, previousReferenceRotationEnd, previousSPositionEnd, totalArcLength, totalChordLength, xARE, xARM, xARS, yARE, yARM, yARS, zARE, zARM, and zARS.

BDSBeamline::BDSBeamline	(	G4ThreeVector	initialGlobalPosition,
		G4RotationMatrix *	initialGlobalRotation
	)

Auxiliary constructor that allows a finite poition and rotation to be applied at the beginning of the beamline in global coordinates. Rembmer the maximum extents of the beamline will also be displaced.

Definition at line 46 of file BDSBeamline.cc.

Member Function Documentation

void BDSBeamline::AddComponent ( BDSAcceleratorComponent * component )

Add a component, but check to see if can be dynamically upcast to a line in which case, loop over it and apply AddSingleComponent(BDSAcceleratorComponent* component) to each component

void BDSBeamline::AddSingleComponent ( BDSAcceleratorComponent * component )

Add a single component and calculate its position and rotation with respect to the beginning of the beamline

void BDSBeamline::ApplyTransform3D ( BDSTransform3D * component )

Apply a Transform3D rotation and translation to the reference coordinates. Special method for the special case of unique component Transform3D. Modifies the end rotation and position of the last element in the beamline. Note this applies the offset dx,dy,dz first, then the rotation of coordinates
