Handling named properties
PropertyManager contains an vector of NamedProperty objects. Each of the NamedProeprty objects has to have a unique name. The setProperty methods ensure the uniqueness of this name. If a setProperty method is called for an existing name, the existing object is destructed prior to the insertion of the new object.

Detailed Description

Property Manager class. This class manages properties of a class. A property can be seen as easy way to extend the class BALL_EXPORT' attributes without changing its interface. There are different types of properties defined depending on the kind of data stored. The simplest kind of property is just stored as a boolean information: Either an object has a certain property, or it does not. These properties are obviously coded as a BitVector. However the meaning of the different bits has to be defined and the uniqueness of this meaning has to be guaranteed. In order to avoid this, all kernel classes derived from PropertyManager contain a public enum that defines a value NUMBER_OF_PROPERTIES. All user defined properties should refer to this constant (e.g. by defining MY_PROPERTY = Molecule::NUMBER_OF_PROPERTIES + 1).

: The second way of storing properties is much more flexible, but less efficient. It uses the class NamedProperty that also allows to store additional information along with the property. In this case, each property is accessed via a unique name.
