From class


        
          java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long timeout, int nanos)` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
`final void`	`wait(long timeout)` Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.
`final void`	`wait()` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.

Public methods

getPrivateData

public byte[] getPrivateData ()

Retrieves the private data in the CA_Descriptor associated with a track. Some CAS systems may need this to initialize the CAS plugin object. This private data can only be retrieved before a valid MediaCas object is set on the extractor.

Returns
`byte[]`	a byte array containing the private data. A null return value indicates that the private data is unavailable. An empty array, on the other hand, indicates that the private data is empty (zero in length).

getSession

public MediaCas.Session getSession ()

Retrieves the MediaCas.Session associated with a track. The session is needed to initialize a descrambler in order to decode the scrambled track. The session object can only be retrieved after a valid MediaCas object is set on the extractor.

Returns
`MediaCas.Session`	a `MediaCas.Session` object associated with a track.

MediaExtractor.setMediaCas(MediaCas)

getSystemId

public int getSystemId ()

Retrieves the system id of the conditional access system.

Returns
`int`	CA system id of the CAS used to scramble the track.
