VertexType Class

All vertices have a type that is identified as a VertexType. Each VertexType have a name, can be persisted and tracks all vertices of its type. The vertex type also knows about properties used by its type.

<SerializableAttribute>
Public Class VertexType
	Inherits OptimizedPersistable

The VertexType type exposes the following members.

Properties

	Name	Description
	EdgeTypes	All edge types connected with this vertex type.
	MyGraph	Graph for which this VertexType belongs to
	SubTypes	Sub types of this VertexType
	TypeId	Get the unique id of the vertex type.
	TypeName	Gets the name of this VertexType

Methods

	Name	Description
	CountVertices	Count of vertcies
	FindProperty	Gets the associated PropertyType given a property type name or null if such property type doesn't exist.
	GetEdges(EdgeType, Direction)	Enumerates edges connected wih this vertex type
	GetEdges(Vertex, Direction)	Get all edges found from a given Vertex
	GetEdges(EdgeType, Vertex, Direction, Vertex)	Get all edges found between two vertices
	GetNumberOfEdges(EdgeType, Direction)	Get the number of edges of a certain type that can be found and an edge direction
	GetNumberOfEdges(EdgeType, Int32, Direction)	Get the number of edges of a certain type that can be found associated with a vertex id and an edge direction
	GetNumberOfEdges(EdgeType, Int32, Int32, Direction)	Get the number of edges of a certain type that can be found associated with a vertex id, another vertex id at other end and an edge direction
	GetPropertyKeys	Return all the keys associated with the vertex type.
	GetPropertyTypes	Return all the property types associated with vertex type.
	GetPropertyValue	Get the property value for a Vertex
	GetTopNumberOfEdges	Get the top vertices with the most number of edges of the given edge type
	GetVertex	Instantiates a Vertex if it exist
	GetVerticeIds	Get existing Vertex ids for this type
	GetVertices(Boolean)	Enumerates all vertices for the given type
	GetVertices(EdgeType, Vertex, Direction)	Get an enumeration of existing vertices of this type found by following an edge type
	NewProperty	Creates a new Property.
	NewVertex	Creates a new Vertex
	Remove	Removes this VertexType from a graph. An exception is thrown if the VertexType is in use.
	RemoveVertex	Removes a vertex from this type and graph
	SetPropertyValue	Sets a property value
	ToString	Displays class name plus object id (Overrides OptimizedPersistableToString.)
	Unpersist	Removes an object from the persistent store and makes the object a transient object. It does not automatically make referenced objects unpersisted. Best way to do so is to override this virtual function in your own classes. (Overrides OptimizedPersistableUnpersist(SessionBase).)
