javax.sound.sampled.Line.Info
javax.sound.sampled.Port.Info
- Enclosing interface:
- Port
The
Port.Info class extends Line.Info with additional
information specific to ports, including the port's name and whether it
is a source or a target for its mixer. By definition, a port acts as
either a source or a target to its mixer, but not both. (Audio input
ports are sources; audio output ports are targets.)
To learn what ports are available, you can retrieve port info objects
through the getSourceLineInfo and
getTargetLineInfo methods of the
Mixer interface. Instances of the Port.Info class may
also be constructed and used to obtain lines matching the parameters
specified in the Port.Info object.

Method Details
-
getName
Obtains the name of the port.- Returns:
- the string that names the port
-
isSource
public boolean isSource()Indicates whether the port is a source or a target for its mixer.- Returns:
trueif the port is a source port (such as a microphone),falseif the port is a target port (such as a speaker)
-
matches
Indicates whether this info object specified matches this one. To match, the match requirements of the superclass must be met and the types must be equal. -
equals
Indicates whether the specified object is equal to this info object, returningtrueif the objects are the same. -
hashCode
public final int hashCode()Returns a hash code value for this info object. -
toString
Returns a string representation of the info object.
