Member Function Documentation

◆ onApiCallExecuted()

virtual void agora::rtc::IRtcConnectionObserver::onApiCallExecuted ( int  err,
const char *  api,
const char *  result 
)
inlinevirtual

Occurs when an API method is executed.

Parameters
errThe error code that the SDK reports when the method call fails. If the SDK reports 0, the method call succeeds.
apiThe API method that is executed.
resultThe result of the method call.

◆ onChangeRoleFailure()

virtual void agora::rtc::IRtcConnectionObserver::onChangeRoleFailure ( )
inlinevirtual

Occurs when the local user fails to change the user role.

◆ onChangeRoleSuccess()

virtual void agora::rtc::IRtcConnectionObserver::onChangeRoleSuccess ( CLIENT_ROLE_TYPE  oldRole,
CLIENT_ROLE_TYPE  newRole 
)
inlinevirtual

Occurs when the role of the local user changes.

Parameters
oldRoleThe previous role of the local user: CLIENT_ROLE_TYPE.
newRoleThe current role of the local user: CLIENT_ROLE_TYPE.

◆ onChannelMediaRelayStateChanged()

virtual void agora::rtc::IRtcConnectionObserver::onChannelMediaRelayStateChanged ( int  state,
int  code 
)
pure virtual

Occurs when the state of the channel media relay changes.

Parameters
stateThe state code:
  • RELAY_STATE_IDLE(0): The SDK is initializing.
  • RELAY_STATE_CONNECTING(1): The SDK tries to relay the media stream to the destination channel.
  • RELAY_STATE_RUNNING(2): The SDK successfully relays the media stream to the destination channel.
  • RELAY_STATE_FAILURE(3): A failure occurs. See the details in code.
codeThe error code:
  • RELAY_OK(0): The state is normal.
  • RELAY_ERROR_SERVER_ERROR_RESPONSE(1): An error occurs in the server response.
  • RELAY_ERROR_SERVER_NO_RESPONSE(2): No server response. You can call the leaveChannel method to leave the channel.
  • RELAY_ERROR_NO_RESOURCE_AVAILABLE(3): The SDK fails to access the service, probably due to limited resources of the server.
  • RELAY_ERROR_FAILED_JOIN_SRC(4): Fails to send the relay request.
  • RELAY_ERROR_FAILED_JOIN_DEST(5): Fails to accept the relay request.
  • RELAY_ERROR_FAILED_PACKET_RECEIVED_FROM_SRC(6): The server fails to receive the media stream.
  • RELAY_ERROR_FAILED_PACKET_SENT_TO_DEST(7): The server fails to send the media stream.
  • RELAY_ERROR_SERVER_CONNECTION_LOST(8): The SDK disconnects from the server due to poor network connections. You can call the leaveChannel method to leave the channel.
  • RELAY_ERROR_INTERNAL_ERROR(9): An internal error occurs in the server.
  • RELAY_ERROR_SRC_TOKEN_EXPIRED(10): The token of the source channel has expired.
  • RELAY_ERROR_DEST_TOKEN_EXPIRED(11): The token of the destination channel has expired.

◆ onConnected()

)
pure virtual

Occurs when the connection state between the SDK and the Agora channel changes to CONNECTION_STATE_CONNECTING(2).

Parameters
connectionInfoThe information of the connection. See TConnectionInfo.
reasonThe reason of the connection state change. See CONNECTION_CHANGED_REASON_TYPE.

◆ onConnectionFailure()

virtual void agora::rtc::IRtcConnectionObserver::onConnectionFailure ( const TConnectionInfo connectionInfo,
CONNECTION_CHANGED_REASON_TYPE  reason 
)
pure virtual

Occurs when the connection state between the SDK and the Agora channel changes to CONNECTION_STATE_FAILED(5).

Parameters

◆ onConnectionLost()

virtual void agora::rtc::IRtcConnectionObserver::onConnectionLost ( const TConnectionInfo connectionInfo)
pure virtual

Occurs when the SDK loses connection with the Agora channel.

Parameters
connectionInfoThe information of the connection. See TConnectionInfo.

◆ onDisconnected()

virtual void agora::rtc::IRtcConnectionObserver::onDisconnected ( const TConnectionInfo connectionInfo,
CONNECTION_CHANGED_REASON_TYPE  reason 
)
pure virtual

Occurs when the connection state between the SDK and the Agora channel changes to CONNECTION_STATE_DISCONNECTED(1).

Parameters
connectionInfoThe information of the connection. See TConnectionInfo.
reasonThe reason of the connection state change. See CONNECTION_CHANGED_REASON_TYPE.

◆ onEncryptionError()

virtual void agora::rtc::IRtcConnectionObserver::onEncryptionError ( ENCRYPTION_ERROR_TYPE  errorType)
inlinevirtual
