setPropertyData(address:qualifier:data:)

Declaration

func setPropertyData(address: AudioObjectPropertyAddress, qualifier: Data? = nil, data: Data) throws

Parameters

• address:

  An AudioObjectPropertyAddress indicating which property is being changed.

• qualifier:

  A buffer of data to be used in determining the data of the property being set. Note that not all properties require qualification, in which case this value will be nil.

• data:

  The buffer containing the data to be used to change the property’s value.

Discussion

Note that the value of the property should not be considered changed until the HAL has called the listeners as many properties values are changed asynchronously.
