Enclosing class:

A2AServiceGrpc

public static final class A2AServiceGrpc.A2AServiceBlockingStub
extends io.grpc.stub.AbstractBlockingStub<A2AServiceGrpc.A2AServiceBlockingStub>

A stub to allow clients to do limited synchronous rpc calls to service A2AService.

A2AService defines the gRPC version of the A2A protocol. This has a slightly
different shape than the JSONRPC version to better conform to AIP-127,
where appropriate. The nouns are AgentCard, Message, Task and
TaskPushNotificationConfig.
- Messages are not a standard resource so there is no get/delete/update/list
  interface, only a send and stream custom methods.
- Tasks have a get interface and custom cancel and subscribe methods.
- TaskPushNotificationConfig are a resource whose parent is a task.
  They have get, list and create methods.
- AgentCard is a static resource with only a get method.
fields are not present as they don't comply with AIP rules, and the
optional history_length on the get task method is not present as it also
violates AIP-127 and AIP-131.

build

protected A2AServiceGrpc.A2AServiceBlockingStub build(io.grpc.Channel channel,
 io.grpc.CallOptions callOptions)

Specified by:

build in class io.grpc.stub.AbstractStub<A2AServiceGrpc.A2AServiceBlockingStub>

sendMessage

public SendMessageResponse sendMessage(SendMessageRequest request)

Send a message to the agent. This is a blocking call that will return the
task once it is completed, or a LRO if requested.

sendStreamingMessage

public Iterator<StreamResponse> sendStreamingMessage(SendMessageRequest request)

SendStreamingMessage is a streaming call that will return a stream of
task update events until the Task is in an interrupted or terminal state.

getTask

public Task getTask(GetTaskRequest request)

Get the current state of a task from the agent.

cancelTask

public Task cancelTask(CancelTaskRequest request)

Cancel a task from the agent. If supported one should expect no
more task updates for the task.

taskSubscription

public Iterator<StreamResponse> taskSubscription(TaskSubscriptionRequest request)

TaskSubscription is a streaming call that will return a stream of task
update events. This attaches the stream to an existing in process task.
If the task is complete the stream will return the completed task (like
GetTask) and close the stream.

createTaskPushNotificationConfig

public TaskPushNotificationConfig createTaskPushNotificationConfig(CreateTaskPushNotificationConfigRequest request)

Set a push notification config for a task.

getTaskPushNotificationConfig

public TaskPushNotificationConfig getTaskPushNotificationConfig(GetTaskPushNotificationConfigRequest request)

Get a push notification config for a task.

listTaskPushNotificationConfig

public ListTaskPushNotificationConfigResponse listTaskPushNotificationConfig(ListTaskPushNotificationConfigRequest request)

Get a list of push notifications configured for a task.

getAgentCard

public AgentCard getAgentCard(GetAgentCardRequest request)

GetAgentCard returns the agent card for the agent.

deleteTaskPushNotificationConfig

public com.google.protobuf.Empty deleteTaskPushNotificationConfig(DeleteTaskPushNotificationConfigRequest request)

Delete a push notification config for a task.
