Detailed Description

Volume and mute of the devices that speak the protocol, through their own interface.

The generic UPnP volume control of such a device does not change the volume while the device is in a group (measured by the owner), the device's own setVolume does, and it changes only that device. The row's slider is a percentage: it maps onto the device's own scale from 0 to its max_volume.

Reads block (they run on the reader threads of the rows). Writes return at once: the last value of a device wins while an earlier one is still on its way, so a drag on the slider does not queue up requests.

Constructor & Destructor Documentation

◆ YxcVolumeAccess()

de.yaacc.yxc.YxcVolumeAccess.YxcVolumeAccess	(	ClientSource	clients,
		StateSource	states,
		BooleanSupplier	onMainThread,
		Executor	writer )

Parameters

states	where the last known state comes from, used instead of a read on the main thread
onMainThread	whether the calling thread is the main thread, where no network access is allowed (the media session asks the player for its volume there)

Member Function Documentation

◆ handles()

boolean de.yaacc.yxc.YxcVolumeAccess.handles ( String udn )

Returns: whether the device speaks the protocol (so that the row uses this instead of the UPnP controls)

◆ readMute()

Boolean de.yaacc.yxc.YxcVolumeAccess.readMute ( String udn )

Returns: the mute state, null if it can not be read; on the main thread the last known state answers

Here is the call graph for this function:

◆ readPercent()

int de.yaacc.yxc.YxcVolumeAccess.readPercent ( String udn )

Returns: the volume as a percentage of the device's scale, -1 if it can not be read. On the main thread nothing is read from the network: the last known state answers.
