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

object describes
Methods

Obtains the class of the line that this Line.Info
object describes.
- Returns:
- the described line's class
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:
-
