early_return: bool = False¶

method: str¶

class a2a.client.interceptors.BeforeArgs(input: Any, method: str, agent_card: AgentCard, context: ClientCallContext | None = None, early_return: Any | None = None)¶

Bases: object

Arguments passed to the interceptor before a method call.

agent_card: AgentCard¶
