 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:

Constructor Detail- 
Infopublic 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 object
- name- the string that names the port
- isSource-- trueif the port is a source port (such as a microphone),- falseif the port is a target port (such as a speaker)
 
 
- 
 - 
Method Detail- 
getNamepublic String getName() Obtains the name of the port.- Returns:
- the string that names the port
 
 - 
isSourcepublic 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)
 
 - 
matchespublic 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.
 - 
equalspublic final boolean equals(Object obj) Indicates whether the specified object is equal to this info object, returningtrueif the objects are the same.- Overrides:
- equalsin class- Object
- 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(),- HashMap
 
 - 
hashCodepublic final int hashCode() Returns a hash code value for this info object.- Overrides:
- hashCodein class- Object
- Returns:
- a hash code value for this info object
- See Also:
- Object.equals(java.lang.Object),- System.identityHashCode(java.lang.Object)
