DataSourceDesc

public class DataSourceDesc
extends Object

java.lang.Object
   ↳ android.media.DataSourceDesc


Base class of data source descriptor. Used by MediaPlayer2#setDataSource, MediaPlayer2#setNextDataSource and MediaPlayer2#setNextDataSources to set data source for playback.

Users should use subclasses' builder to change DataSourceDesc.

String getMediaId()

Return the media Id of data source.

long getStartPosition()

Public methods

getEndPosition

public long getEndPosition ()

Return the position in milliseconds at which the playback will end. POSITION_UNKNOWN means ending at the end of source content.

Returns
long the position in milliseconds at which the playback will end

getMediaId

public String getMediaId ()

Return the media Id of data source.

Returns
String the media Id of data source

getStartPosition

public long getStartPosition ()

Return the position in milliseconds at which the playback will start.

Returns
long the position in milliseconds at which the playback will start

toString

public String toString ()

Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.

The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:

 getClass().getName() + '@' + Integer.toHexString(hashCode())
 

Returns
String a string representation of the object.

Protected methods

finalize

protected void finalize ()

Called by the garbage collector on an object when garbage collection determines that there are no more references to the object. A subclass overrides the finalize method to dispose of system resources or to perform other cleanup.

The general contract of finalize is that it is invoked if and when the Java™ virtual machine has determined that there is no longer any means by which this object can be accessed by any thread that has not yet died, except as a result of an action taken by the finalization of some other object or class which is ready to be finalized. The finalize method may take any action, including making this object available again to other threads; the usual purpose of finalize, however, is to perform cleanup actions before the object is irrevocably discarded. For example, the finalize method for an object that represents an input/output connection might perform explicit I/O transactions to break the connection before the object is permanently discarded.

The finalize method of class Object performs no special action; it simply returns normally. Subclasses of Object may override this definition.

The Java programming language does not guarantee which thread will invoke the finalize method for any given object. It is guaranteed, however, that the thread that invokes finalize will not be holding any user-visible synchronization locks when finalize is invoked. If an uncaught exception is thrown by the finalize method, the exception is ignored and finalization of that object terminates.

After the finalize method has been invoked for an object, no further action is taken until the Java virtual machine has again determined that there is no longer any means by which this object can be accessed by any thread that has not yet died, including possible actions by other objects or classes which are ready to be finalized, at which point the object may be discarded.

The finalize method is never invoked more than once by a Java virtual machine for any given object.

Any exception thrown by the finalize method causes the finalization of this object to be halted, but is otherwise ignored.
