Enums Reference

AgentCallbackType

Passive callback type, determines which events the SDK receives:

Enum Value	String Value	Description
`AUDIO_2_LLM`	`audio2llm`	Audio -> ASR+LLM
`AUDIO_2_TTS`	`audio2tts`	Audio -> ASR+LLM+TTS
`ASR_2_LLM`	`asr2llm`	Text -> LLM
`ASR_2_TTS`	`asr2tts`	Text -> LLM+TTS
`ASR_VIDEO_2_TTS`	`asrVideo2tts`	Text+Video -> VLM+TTS
`ASR_VIDEO_2_VLM`	`asrVideo2vlm`	Text+Video -> VLM
`AUDIO_VIDEO_2_TTS`	`audioVideo2tts`	Audio+Video -> VLM+TTS
`AUDIO_VIDEO_2_VLM`	`audioVideo2vlm`	Audio+Video -> VLM
`ILLEGAL`	`illegal`	Invalid type

java

AgentCallbackType type = AgentCallbackType.of("audio2tts"); // String to enum

Greeting signals, state pushes, face UID and video passthrough no longer use dedicated callback types. Override onGreetSignal / onState / onFaceInfo / onVideoFrame on any registered passive callback to receive them.

FlowMode

Task flow mode:

Enum Value	Description
`SIMPLE`	Single-step mode: startRequest carries the complete payload
`COMPLEX`	Multi-step mode: start -> task x N -> end

RobotState

Robot online state:

Enum Value	Description
`ONLINE`	Robot is online (triggers `onRobotOnline`)
`OFFLINE`	Robot is offline (triggers `onRobotOffline`)

AgentPolicy

Interaction policy (internal use, developers need not concern themselves with this):

Enum Value	Description
`PASSIVE`	Passive interaction (robot initiates)
`ACTIVE`	Active interaction (SDK initiates)
`SIGNAL`	Signaling interaction
