Detailed Description

Member Function Documentation

operator=() [1/2]

DeviceListener & midi_ci::DeviceListener::operator= ( const DeviceListener & )

default

operator=() [2/2]

DeviceListener & midi_ci::DeviceListener::operator= ( DeviceListener && )

default

deviceAdded()

virtual void midi_ci::DeviceListener::deviceAdded ( MUID x )

virtual

Called to indicate that a device with the provided MUID was discovered.

To find out more about the device, use Device::getDiscoveryInfoForMuid().

deviceRemoved()

virtual void midi_ci::DeviceListener::deviceRemoved ( MUID x )

virtual

Called to indicate that a device's MUID was invalidated.

If you were previously storing your own information about this device, you should forget that information here.

endpointReceived()

virtual void midi_ci::DeviceListener::endpointReceived ( MUID x, Message::EndpointInquiryResponse response )

virtual

Called to indicate that endpoint information was received for the given device.

See the MIDI-CI spec for an explanation of the different status codes.

messageNotAcknowledged()

virtual void midi_ci::DeviceListener::messageNotAcknowledged ( MUID x, Message::NAK  )

virtual

Called to indicate that a NAK message was received.

This is useful e.g. to display a diagnostic to the user, or to cache the failed request details and retry the request at a later date.

The message field of the NAK is 7-bit text. You can convert it to a string using Encodings::stringFrom7BitText().

profileStateReceived()

virtual void midi_ci::DeviceListener::profileStateReceived ( MUID x, ChannelInGroup destination )

virtual

Called to indicate that another device reported its enabled and disabled profiles on a particular channel.

See also

Device::getProfileStateForMuid()

profilePresenceChanged()

virtual void midi_ci::DeviceListener::profilePresenceChanged ( MUID x, ChannelInGroup destination, Profile profile, bool exists )

virtual

Called to indicate that a profile was added or removed.

profileEnablementChanged()

virtual void midi_ci::DeviceListener::profileEnablementChanged ( MUID x, ChannelInGroup destination, Profile profile, int numChannels )

virtual

Called to indicate that a profile was enabled or disabled.

A channel count of 0 indicates that the profile was disabled.

profileDetailsReceived()

virtual void midi_ci::DeviceListener::profileDetailsReceived ( MUID x, ChannelInGroup destination, Profile profile, std::byte target, Span< const std::byte > data )

virtual

Called to indicate that details about a profile were received.

profileSpecificDataReceived()

virtual void midi_ci::DeviceListener::profileSpecificDataReceived ( MUID x, ChannelInGroup destination, Profile profile, Span< const std::byte > data )

virtual

Called to indicate that data for a profile were received.

Note that this function may be called either when a remote device attempts to send data to one of the local Device's profiles, or when a profile on a remote device produces some data.

Each profile will specify its own mechanism for distinguishing between the two cases if necessary.

propertyExchangeCapabilitiesReceived()

virtual void midi_ci::DeviceListener::propertyExchangeCapabilitiesReceived ( MUID x )

virtual

Called to indicate that another device reported its property exchange capabilities.

See also

Device::getPropertyExchangeCapabilitiesResponseForMuid()

propertySubscriptionDataReceived()

virtual void midi_ci::DeviceListener::propertySubscriptionDataReceived ( MUID x, const PropertySubscriptionData & data )

virtual

Called to indicate that a subscription update was received.

This only receives messages with responder commands (partial, full, notify, end).

To start a subscription, use Device::sendPropertySubscriptionStart().

propertySubscriptionChanged()

virtual void midi_ci::DeviceListener::propertySubscriptionChanged ( SubscriptionKey subscription, const std::optional< String > & subscribeId )

virtual

Called when a remote device updates a subscription by accepting or terminating it.

If the subscription was accepted, the subscribeId will be non-null. Otherwise, a null subscribeId indicates that the subscription was terminated.
