Class ParallelAgent

java.lang.Object

com.google.adk.agents.BaseAgent

com.google.adk.agents.ParallelAgent

public class ParallelAgent
extends BaseAgent

A shell agent that runs its sub-agents in parallel in isolated manner.

This approach is beneficial for scenarios requiring multiple perspectives or attempts on a single task, such as running different algorithms simultaneously or generating multiple responses for review by a subsequent evaluation agent.

fromConfig

public static ParallelAgent fromConfig(ParallelAgentConfig config,
 String configAbsPath)
                                throws ConfigAgentUtils.ConfigurationException

Creates a ParallelAgent from configuration.

Parameters:

config - the agent configuration

configAbsPath - The absolute path to the agent config file.

Returns:

the configured ParallelAgent

Throws:

ConfigAgentUtils.ConfigurationException - if the configuration is invalid

runAsyncImpl

protected io.reactivex.rxjava3.core.Flowable<Event> runAsyncImpl(InvocationContext invocationContext)

Runs sub-agents in parallel and emits their events.

Sets the branch and merges event streams from all sub-agents.

Specified by:

runAsyncImpl in class BaseAgent

Parameters:

invocationContext - Invocation context.

Returns:

Flowable emitting events from all sub-agents.

runLiveImpl

protected io.reactivex.rxjava3.core.Flowable<Event> runLiveImpl(InvocationContext invocationContext)

Not supported for ParallelAgent.

Specified by:

runLiveImpl in class BaseAgent

Parameters:

invocationContext - Invocation context.

Returns:

Flowable that always throws UnsupportedOperationException.
