Uses of Node in com.google.adk.workflow

Classes in com.google.adk.workflow that implement Node

Modifier and Type	Class	Description
class	BaseNode	Base class for nodes in a workflow graph.
final class	JoinNode	A node that waits for every predecessor to complete, then outputs their outputs keyed by predecessor name.
final class	Start	The node that marks where a workflow graph starts.
final class	Workflow	A graph of nodes that is itself a node, so a workflow can go wherever a node can, including in another workflow.

Methods in com.google.adk.workflow that return Node

Modifier and Type	Method	Description
static Node	ToolNodes.asNode(BaseTool tool)	Returns a node named after tool, with the default NodeConfig.
static Node	ToolNodes.asNode(BaseTool tool, String name)	Returns a node named name that runs tool, with the default NodeConfig.
static Node	ToolNodes.asNode(BaseTool tool, String name, NodeConfig config)	Returns a node named name that runs tool with config; session state supplies any required parameter that the input lacks.

Methods in com.google.adk.workflow with parameters of type Node

Modifier and Type	Method	Description
EdgesBuilder.EdgeChain	EdgesBuilder.EdgeChain.chain(Node first, Node second, Node... rest)	Connects the current node to first, second and each node in rest in order, and continues from the last one: g.fromStart().chain(a, b) is short for g.fromStart().then(a).then(b).
EdgesBuilder.EdgeChain	EdgesBuilder.from(Node node)	Starts a chain of edges at node: g.from(a).then(b).then(c).
EdgesBuilder.NodeGroupChain	EdgesBuilder.from(Node first, Node second, Node... rest)	Starts a chain at first, second and each node in rest so they can join without a fan-out: g.from(a, b).joinTo(join).
void	EdgesBuilder.RouteMap.otherwise(Node first, Node... rest)	Leads to each target when no other route of the source node matches, including when it emits none.
static Node	ParallelWorkers.parallelNode(Node node)	Returns a node that runs node on every item at once.
static Node	ParallelWorkers.parallelNode(Node node, int maxParallelWorkers)	Returns a node that runs node on each item of a list input, at most maxParallelWorkers at a time and starting them in input order; the returned node takes node's name, description, state schema and requiresAllPredecessors(), and leaves its config and input and output schemas to each item's run.
static io.reactivex.rxjava3.core.Maybe<Object>	NodeRunner.runChild(Context parent, Node node, @Nullable Object nodeInput, RunNodeConfig config)	Runs node as a child of the node whose context is parent, as Context.runNode(Node, Object, RunNodeConfig) describes.

EdgesBuilder.NodeGroupChain	EdgesBuilder.EdgeChain.then(Node first, Node second, Node... rest)	Fans out by connecting the current node to first, second and each node in rest, like EdgesBuilder.EdgeChain.then(Collection): g.from(a).then(b, c).joinTo(join).
void	EdgesBuilder.RouteMapEntry.then(Node first, Node... rest)	Leads to first and each node in rest, with one edge to each, when the source node emits any of this entry's routes.

Method parameters in com.google.adk.workflow with type arguments of type Node

Modifier and Type	Method	Description
