A graph builder that constructs a sequential graph from a list of nodes.
Automatically links nodes with one-directional edges from the first to the last
and sets the start and end nodes accordingly.
Constructors Methods Hierarchy Constructors constructor new SequentialGraphBuilder ( opts : SequentialGraphBuilderProps ): SequentialGraphBuilder Creates a new instance of SequentialGraphBuilder and builds the sequential graph.
Parameters opts
SequentialGraphBuilderProps
required
The configuration options for the sequential graph builder.
Returns SequentialGraphBuilderOverrides GraphBuilder .constructor Methods addSequentialNode addSequentialNode ( node : AbstractNode ): SequentialGraphBuilder Adds a node to the graph, links it from the previous end node (if any),
and sets the passed node as the new end node.
Parameters The node to add to the graph.
Returns SequentialGraphBuilderThe current builder instance.
addComponent addComponent ( component : Component | AbstractComponent ): this Adds a component to the graph configuration.
Parameters component
Component | AbstractComponent
required
Component to add to the graph
Returns thisThe graph instance for method chaining
Inherited from GraphBuilder .addComponent addEdge addEdge ( fromNode : string | Node | AbstractNode , toNode : string | Node | AbstractNode , options ?: { condition? : CustomEdgeConditionReference | EdgeConditionCallback ; conditionExpression ?: string ; loop ?: boolean ; optional ?: boolean ; }, ): this Adds an edge connecting two nodes in the graph.
Parameters fromNode
string | Node | AbstractNode
required
Source node
toNode
string | Node | AbstractNode
required
Destination node
Optional edge configuration condition
CustomEdgeConditionReference | EdgeConditionCallback
Reference to a registered custom condition or a callback to register one
CEL expression for conditional execution
Whether the edge creates a loop
Whether the edge is optional
Returns thisThe builder instance for method chaining
Inherited from GraphBuilder .addEdge addIntentSubgraph addIntentSubgraph ( id : string , parameters : IntentSubgraphProps , ): SequentialGraphBuilder Adds an intent subgraph to the graph.
Parameters Unique identifier for the subgraph
parameters
IntentSubgraphProps
required
Intent subgraph parameters Array of intent configurations
Template for LLM prompting
LLM component instance or configuration
Embedder component instance or configuration
Similarity threshold for matching
Text generation configuration
Maximum intents to send to LLM
Maximum phrases per intent
embeddingSimilarityThreshold
Embedding similarity threshold
Number of top intents to return
Returns SequentialGraphBuilderThe graph instance for method chaining
Inherited from GraphBuilder .addIntentSubgraph addNode addNode ( node : Node | AbstractNode ): this Adds a node to the graph.
If an AbstractNode is provided without corresponding component, internal components are automatically added.
Parameters node
Node | AbstractNode
required
Node to add to the graph
Returns thisThe graph instance for method chaining
Inherited from GraphBuilder .addNode addSubgraph addSubgraph ( subgraph : SubgraphBuilder ): this Adds a subgraph to the graph configuration.
Parameters Subgraph builder instance to be added
Returns thisThe graph instance for method chaining
Inherited from GraphBuilder .addSubgraph build Creates a graph executor instance for running the graph.
Returns Graph GraphExecutor instance configured with this graph
Inherited from GraphBuilder .build setEndNode setEndNode ( node : string | Node | AbstractNode ): this Sets the end node of the graph.
Parameters node
string | Node | AbstractNode
required
End node
Returns thisThe graph instance for method chaining
Inherited from GraphBuilder .setEndNode setEndNodes setEndNodes ( nodes : ( string | Node | AbstractNode )[]): this Sets multiple end nodes for the graph.
Parameters nodes
(string | Node | AbstractNode)[]
required
Array of end nodes
Returns thisThe graph instance for method chaining
Inherited from GraphBuilder .setEndNodes setStartNode setStartNode ( node : string | Node | AbstractNode ): this Sets the start node of the graph.
Parameters node
string | Node | AbstractNode
required
Start node
Returns thisThe graph instance for method chaining
Inherited from GraphBuilder .setStartNode setStartNodes setStartNodes ( nodes : ( string | Node | AbstractNode )[]): this Sets multiple start nodes for the graph.
Parameters nodes
(string | Node | AbstractNode)[]
required
Array of start nodes
Returns thisThe graph instance for method chaining
