CloneablePullBufferDataSource

• java.lang.Object
  • javax.media.protocol.DataSource
    • javax.media.protocol.PullBufferDataSource

Fields Summary
private SuperCloneableDataSource	superClass

Constructors Summary
public CloneablePullBufferDataSource(PullBufferDataSource source) Constructor param source the source to be cloned superClass = new SuperCloneableDataSource(source);

Methods Summary
public void	connect() Open a connection to the source described by the MediaLocator. The connect method initiates communication with the source. exception IOException Thrown if there are IO problems when connect is called. superClass.connect();
public javax.media.protocol.DataSource	createClone() Clone the original datasource, returning an object of the type PushDataSource or PushBufferDataSource. If the original data source was a PullDataSource, then this will be a PushDataSource which pushes at the same rate at which the CloneableDataSource is being pulled. return a slave DataSource for this DataSource. return superClass.createClone();
public void	disconnect() Close the connection to the source described by the locator. The disconnect method frees resources used to maintain a connection to the source. If no resources are in use, disconnect is ignored. If stop hasn't already been called, calling disconnect implies a stop. superClass.disconnect();
public java.lang.String	getContentType() Get a string that describes the content-type of the media that the source is providing. It is an error to call getContentType if the source is not connected. return The name that describes the media content. return superClass.getContentType();
public java.lang.Object	getControl(java.lang.String controlType) Obtain the object that implements the specified Class or Interface The full class or interface name must be used. If the control is not supported then null is returned. return the object that implements the control, or null. return superClass.getControl(controlType);
public java.lang.Object[]	getControls() Obtain the collection of objects that control the object that implements this interface. If no controls are supported, a zero length array is returned. return the collection of object controls return superClass.getControls();
public javax.media.Time	getDuration() Get the duration of the media represented by this object. The value returned is the media's duration when played at the default rate. If the duration can't be determined (for example, the media object is presenting live video) getDuration returns DURATION_UNKNOWN. return A Time object representing the duration or DURATION_UNKNOWN. return superClass.getDuration();
public javax.media.protocol.PullBufferStream[]	getStreams() Get the collection of streams that this source manages. The collection of streams is entirely content dependent. The ContentDescriptor of this DataSource provides the only indication of what streams can be available on this connection. return The collection of streams for this source. if (superClass.streams == null) { superClass.streams = new PullBufferStream[superClass.streamsAdapters.length]; for (int i = 0; i < superClass.streamsAdapters.length; i++) superClass.streams[i] = (PullBufferStream)superClass.streamsAdapters[i].getAdapter(); } return (PullBufferStream[])superClass.streams;
public void	start() Initiate data-transfer. The start method must be called before data is available. (You must call connect before calling start.) exception IOException Thrown if there are IO problems with the source when start is called. superClass.start();
public void	stop() Stop the data-transfer. If the source has not been connected and started, stop does nothing. superClass.stop();
