Syntax

Copy

public abstract class LGSPNode : INode, 
	IGraphElement, IAttributeBearer, ITyped, IDeepEqualityComparer, ICallable

The LGSPNode type exposes the following members.

Constructors

	Name	Description
	LGSPNode	Instantiates an LGSPNode object.

Properties

	Name	Description
	Incident	Returns an IEnumerable<IEdge> over all incident edges
	Incoming	Returns an IEnumerable<IEdge> over all incoming edges
	Item	Indexer that gives access to the attributes of the graph element.
	Outgoing	Returns an IEnumerable<IEdge> over all outgoing edges
	ReplacedByElement	The element which replaced this element (Valid is false in this case) or null, if this element has not been replaced or is still a valid member of a graph.
	ReplacedByNode	The node which replaced this node (Valid is false in this case) or null, if this node has not been replaced or is still a valid member of a graph.
	Type	The NodeType of the node.
	Valid	This is true, if this node is a valid graph element, i.e. it is part of a graph.

Methods

	Name	Description
	ApplyFunctionMethod	Executes the function method given by its name. Throws an exception if the method does not exists or the parameters are of wrong types.
	ApplyProcedureMethod	Executes the procedure method given by its name. Throws an exception if the method does not exists or the parameters are of wrong types.
	Clone	Creates a shallow clone of this node. All attributes will be transfered to the new node. The node will not be associated to a graph, yet. So it will not have any incident edges nor any assigned variables.
	Copy	Creates a deep copy of this node (i.e. (transient) class objects will be replicated). All attributes will be transfered to the new node. The node will not be associated to a graph, yet. So it will not have any incident edges nor any assigned variables.
	GetAttribute	Returns the graph element attribute with the given attribute name. If the graph element type doesn't have an attribute with this name, a NullReferenceException is thrown.
	GetCompatibleIncident	Returns an IEnumerable<IEdge> over all incident edges with the same type or a subtype of the given type
	GetCompatibleIncoming	Returns an IEnumerable<IEdge> over all incoming edges with the same type or a subtype of the given type
	GetCompatibleOutgoing	Returns an IEnumerable<IEdge> over all outgoing edges with the same type or a subtype of the given type
	GetExactIncident	Returns an IEnumerable<IEdge> over all incident edges with exactly the given type
	GetExactIncoming	Returns an IEnumerable<IEdge> over all incoming edges with exactly the given type
	GetExactOutgoing	Returns an IEnumerable<IEdge> over all outgoing edges with exactly the given type
	InstanceOf	Returns true, if the typed object is compatible to the given type.
	IsDeeplyEqual	Returns whether this and that are deeply equal, which means the scalar attributes are equal, the container attributes are memberwise deeply equal, and object attributes are deeply equal. (If types are unequal the result is false.) Visited objects are/have to be stored in the visited objects dictionary in order to detect shortcuts and cycles.
	MoveInHeadAfter	Moves the head of the incoming list after the given edge. Part of the "list trick".
	MoveOutHeadAfter	Moves the head of the outgoing list after the given edge. Part of the "list trick".
	Recycle	Recycles this node. This may pool the node or just ignore it.
	ResetAllAttributes	Resets all graph element attributes to their initial values.
	SetAttribute	Sets the graph element attribute with the given attribute name to the given value. If the graph element type doesn't have an attribute with this name, a NullReferenceException is thrown.
	ToString	Returns the name of the type of this node. (Overrides ObjectToString.)

Fields

	Name	Description
	lgspFlags	contains some booleans coded as bitvector
	lgspInhead	Entry node into the incoming edges list - not of type edge head, real edge or null
	lgspOuthead	Entry node into the outgoing edges list - not of type edge head, real edge or null
	lgspType	The node type of the node.
	lgspTypeNext	Next node in the list containing all the nodes of one type. See comment for lgspTypePrev (this node has been retyped if typeNext is not null but typePrev is null).
	lgspTypePrev	Previous node in the list containing all the nodes of one type. The node is not part of a graph, iff typePrev is null. If typePrev is null and typeNext is not null, this node has been retyped and typeNext points to the new node. These special cases are neccessary to handle the following situations: "delete node + return edge", "hom + delete + return", "hom + retype + return", "hom + retype + delete", "hom + retype + delete + return".
