Uses of Experimental in com.google.adk.agents

Methods in com.google.adk.agents with annotations of type Experimental

Modifier and Type	Method	Description
Map<String, Map<String,Object>>	InvocationContext.agentStates()	Returns an unmodifiable view of the per-agent resumability checkpoint states for this invocation, keyed by agent name.
Map<String,Boolean>	InvocationContext.endOfAgents()	Returns an unmodifiable view of the per-agent end-of-agent flags for this invocation, keyed by agent name.
com.google.common.collect.ImmutableList<Event>	InvocationContext.events(boolean currentInvocation, boolean currentBranch)	Returns the current session's events, optionally filtered to the current invocation and/or the current branch.
boolean	InvocationContext.isResumable()	Returns whether the current invocation is resumable.
void	InvocationContext.populateInvocationAgentStates()	Rehydrates InvocationContext.agentStates() and InvocationContext.endOfAgents() from the current invocation's history when this invocation is resumable.
io.reactivex.rxjava3.core.Flowable<Event>	BaseAgent.runNode(Context context, @Nullable Object nodeInput)	Runs this agent as a workflow node through its BaseAgent.runAsync(InvocationContext) lifecycle, including its callbacks.
boolean	InvocationContext.shouldPauseInvocation(Event event)	Returns whether to pause the invocation right after this event: it is resumable and the event carries a long-running function call, including a synthetic adk_request_confirmation HITL request.

Uses of Experimental in com.google.adk.apps

Classes in com.google.adk.apps with annotations of type Experimental

Modifier and Type	Class	Description
class	ResumabilityConfig	Resumability config for every agent in an app: pause on a long-running call and resume from the last event.

Methods in com.google.adk.apps with annotations of type Experimental

Modifier and Type	Method	Description
App.Builder	App.Builder.resumabilityConfig(ResumabilityConfig resumabilityConfig)
@Nullable ResumabilityConfig	App.resumabilityConfig()

Uses of Experimental in com.google.adk.events

Methods in com.google.adk.events with annotations of type Experimental

Modifier and Type	Method	Description
Event.Builder	Event.Builder.nodeInfo(@Nullable NodeInfo value)
Optional<NodeInfo>	Event.nodeInfo()	Identifies the workflow-node activation that emitted this event; outside a workflow, this value is empty or has an empty path.
Event.Builder	Event.Builder.output(@Nullable Object value)
Optional<Object>	Event.output()	For a workflow node, returns the value handed to successors, distinct from Event.content(), or empty when the event carries no node output.
EventActions.Builder	EventActions.Builder.route(@Nullable List<Route> value)
Optional<com.google.common.collect.ImmutableList<Route>>	EventActions.route()	For a workflow node, returns the routes this event selects; an edge is followed when it has one of these routes.
void	Event.setNodeInfo(@Nullable NodeInfo nodeInfo)
void	Event.setOutput(@Nullable Object output)
void	EventActions.setRoute(@Nullable List<Route> route)

Uses of Experimental in com.google.adk.runner

Methods in com.google.adk.runner with annotations of type Experimental

Modifier and Type	Method	Description
io.reactivex.rxjava3.core.Flowable<Event>	Runner.runAsync(String userId, String sessionId, @Nullable String invocationId, @Nullable com.google.genai.types.Content newMessage, RunConfig runConfig, @Nullable Map<String,Object> stateDelta)	Runs the agent, resuming an existing invocation instead of starting a new one.

Uses of Experimental in com.google.adk.workflow

Classes in com.google.adk.workflow with annotations of type Experimental

Modifier and Type	Class	Description
class	BaseNode	Base class for nodes in a workflow graph.
final record	Edge	A connection between two 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.
class	NodeConfig	A node's retry policy and execution timeout.
class	NodeInfo	The identity of the workflow-node activation that emitted an Event.
class	RetryConfig	How a node is retried when it fails.
interface	Route	A value on a workflow edge, and the value a node emits to select which of its outgoing edges are followed.
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 with annotations of type Experimental

Modifier and Type	Method	Description
default NodeConfig	Node.config()	Returns the node's retry policy and execution timeout.
default Optional<com.google.genai.types.Schema>	Node.inputSchema()	Returns the schema the node's input must match.
default Optional<com.google.genai.types.Schema>	Node.outputSchema()	Returns the schema that the node's output value must match.
default boolean	Node.requiresAllPredecessors()	Returns true if the node runs only once every predecessor has completed, receiving all their outputs keyed by node name, as a fan-in node does.
default boolean	Node.rerunOnResume()	Returns true if a resumed node runs again from scratch, rather than completing with the resuming answer as its output.
io.reactivex.rxjava3.core.Flowable<?>	Node.runNode(Context context, @Nullable Object nodeInput)	Runs the node on nodeInput, the output it receives from its predecessors.
default Optional<com.google.genai.types.Schema>	Node.stateSchema()	Returns the schema declaring the state keys the node uses.
default boolean	Node.waitForOutput()	Returns true if the node stays re-triggerable until it produces an output or a route, instead of completing when its run completes.
