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.

for the specified info object must be compatible with that of this
one.
Subclasses may add other criteria to determine whether the two objects
