Detailed Description

Pointers are connections between two nodes in the data structure.

They are usually unidirectional and hold several properties. Properties can accessed directly by the getter methods or (also from the script engine) be created by 'add_property(name, value)' and access by 'pointer.propertyName'.

Definition at line 48 of file Pointer.h.
