Detailed Description

BraggScatterer is a general interface for representing scatterers in the unit cell of a periodic structure.

Since there are many possibilities of modelling scatterers, BraggScatterer is derived from PropertyManager. This way, new scatterers with very different parameters can be added easily.

New implementations must override the declareProperties method and define any parameters there. For most applications it should be easier to inherit from BraggScattererInCrystalStructure, which provides some default properties that are useful in many cases. CompositeBraggScatterer is designed to combine several scatterers.

CompositeBraggScatterer does not declare any properties by itself. For some properties it makes sense to be equal for all scatterers in the composite. This behavior can be achieved by calling the method makePropertyPropagating after it has been declared. Examples are the UnitCell and SpaceGroup properties in BraggScattererInCrystalStructure.

Construction of concrete scatterers is done through ScattererFactory.

◆ declareProperties()

virtual void Mantid::Geometry::BraggScatterer::declareProperties ( )

Base implementation does nothing - for implementing classes only.

Definition at line 74 of file BraggScatterer.h.

Referenced by initialize().

◆ exposePropertyToComposite()

void Mantid::Geometry::BraggScatterer::exposePropertyToComposite ( const std::string & propertyName )

protected

Exposes the property with the supplied name to BraggScattererComposite.

When a property is marked to be exposed to BraggScattererComposite, the composite also declares this property and tries to propagate the value assigned to the composite's property to all its members.

Parameters

propertyName :: Name of the parameter that should be exposed.
