GraphShell Class

Container and controller for nodes.

Definition

Namespace: Quine.Graph
Assembly: Quine.Graph (in Quine.Graph.dll) Version: 1.0.0+0ea0706914ee4edf2b0ed66bec3ab4d062a43b68

C#

public sealed class GraphShell : GraphSchemaHook<GraphState>

Inheritance: Object GraphSchemaHook GraphSchemaHookGraphState GraphShell

Remarks

Incrementally constructed graph should not be considered runnable because ctors of nodes may use introspection (e.g., finding out the number of successor nodes). In these cases, introspection will return wrong results and the graph will not run properly. The state-based constructor must ALWAYS be used to run the graph.

Constructors

GraphShell

Constructor. The graph cannot be run before Build has been invoked.

Properties

Id	(Inherited from GraphSchemaHook)
Nodes
Owner	Parent/owner of this node, or null. (Inherited from GraphSchemaHook)
PathId	Provides IDs of all job nodes from the root (1st element) to this. The byte array is a sequence of integer ids with variable-length encoding (7-bit). (Inherited from GraphSchemaHook)
State	Strongly-typed state. This is NOT an override, but hiding. (Inherited from GraphSchemaHookT)

Methods

Build	This method must be invoked before starting the graph. For technical reasons, two-phase initialization is necessary.
Cancel	Cancels graph execution. This method is a no-op if the graph is not currently running (not started or completed).
RunAsync	Starts an asynchronous run of the graph. When completed, all state is finalized and won't be changed asynchronously. This method can be invoked only once.

Events

InteractiveQuery	Fired when a node is requesting interactive input.
ItemProcessing	Fired when a node starts processing a message, ends processing, or reports progress.
RunState	Fired on graph/node run state change.
ShellTrace	Fired on every trace message.
