public static class Port.Info extends Line.Info
ThePort.Infoclass extendsLine.Infowith 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
getSourceLineInfoandgetTargetLineInfomethods of theMixerinterface. Instances of thePort.Infoclass may also be constructed and used to obtain lines matching the parameters specified in thePort.Infoobject.- Since:

Info
public Info(Class<?> lineClass, String name, boolean isSource)
Constructs a port's info object from the information given. This constructor is typically used by an implementation of Java Sound to describe a supported line.- Parameters:
lineClass- the class of the port described by the info objectname- the string that names the portisSource-trueif the port is a source port (such as a microphone),falseif the port is a target port (such as a speaker)
-

Method Detail
-
getName
public String 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
public boolean matches(Line.Info info)
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
public final boolean equals(Object obj)
Indicates whether the specified object is equal to this info object, returningtrueif the objects are the same.- Overrides:
equalsin classObject- Parameters:
obj- the reference object with which to compare- Returns:
trueif the specified object is equal to this info object;falseotherwise- See Also:
Object.hashCode()
-
hashCode
public final int hashCode()
Returns a hash code value for this info object.- Overrides:
hashCodein classObject- Returns:
- a hash code value for this info object
