C# Class Smrf.NodeXL.Adapters.GraphMLAttribute

Represents a GraphML vertex or edge attribute parsed from a GraphML file.

This class is used by GraphMLGraphAdapter while it is parsing a GraphML file.

In GraphML, a "key" XML node defines an edge or vertex attribute, which GraphML calls a "Graph-ML attribute," and a "data" XML node specifies the GraphML-attribute's value for a specific vertex or edge. The constructor parses the "key" XML node, and the GetAttributeValue parses a "data" XML node. provides a default value for the GraphML-attribute, if one was specified.

NodeXL doesn't support the for="graph" or for="all" attribute values allowed by the GraphML specification. The caller should filter out such "key" XML nodes before using this class to parse them.
