public static class Line.Info extends Object
ALine.Info
object contains information about a line. The only information provided byLine.Info
itself is the Java class of the line. A subclass ofLine.Info
adds other kinds of information about the line. This additional information depends on whichLine
subinterface is implemented by the kind of line that theLine.Info
subclass describes.A
Line.Info
can be retrieved using various methods of theLine
,Mixer
, andAudioSystem
interfaces. Other such methods let you pass aLine.Info
as an argument, to learn whether lines matching the specified configuration are available and to obtain them.- Since:

matches
public boolean matches(Line.Info info)
Indicates whether the specified info object matches this one. To match, the specified object must be identical to or a special case of this one. The specified info object must be either an instance of the same class as this one, or an instance of a sub-type of this one. 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:
info
- the info object which is being compared to this one- Returns:
true
if the specified object matches this one,false
otherwise
