Examples of net.sf.graphiti.model.Configuration

net.sf.graphiti.model.Configuration
This class provides the configuration for a {@link Graph}. A configuration is defined by an extension point, and contains attributes and parameters that are defined for the graph, vertices and edges.
Attributes are specified for classes of objects: for example, all vertices of type T will have an attribute A which has the value V. Examples of such attributes for vertices are "shape" or "color".

Parameters are specified for each instance of graph/vertex/edge. Examples of parameters are position or id.
