Detailed Description

Stores additional attributes of a graph (like layout information).

It is frequently necessary to associate additional attributes with a graph. The class GraphAttributes provides various such attributes and is the central place were such attributes are stored.

Attributes are simply stored in node or edge arrays; for memory consumption reasons, only a subset of these arrays is in fact initialized for the graph; non-initialized arrays require only a few bytes of extra memory.

Which arrays are initialized is specified by a bit vector; each bit in this bit vector corresponds to one or more attributes. E.g., nodeGraphics corresponds to the attributes m_x, m_y, m_width, and m_height; whereas edgeDoubleWeight only corresponds to the attribute m_doubleWeight.

Attributes can be initialized by the constructor GraphAttributes(const Graph &,long) or the function initAttributes(); attributes can also be deinitialized by calling destroyAttributes().
