public static class Line.Info extends Object
ALine.Infoobject contains information about a line. The only information provided byLine.Infoitself is the Java class of the line. A subclass ofLine.Infoadds other kinds of information about the line. This additional information depends on whichLinesubinterface is implemented by the kind of line that theLine.Infosubclass describes.A
Line.Infocan be retrieved using various methods of theLine,Mixer, andAudioSysteminterfaces. Other such methods let you pass aLine.Infoas an argument, to learn whether lines matching the specified configuration are available and to obtain them.- Since:

In addition, the attributes of the specified object must be compatible with the capabilities of this one. Specifically, the routing configuration for the specified info object must be compatible with that of this one. Subclasses may add other criteria to determine whether the two objects match.- Parameters:
