javax.sound.sampled.Line.Info
- Direct Known Subclasses:
DataLine.Info
,Port.Info
- Enclosing interface:
Line
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.
