prefetch

public void prefetch()
              throws java.lang.Exception

Description copied from interface: XSmilesContentHandler

Throws:

java.lang.Exception

play

public void play()
          throws java.lang.Exception

Description copied from interface: XSmilesContentHandler

Plays the media. The media will be added to the container set using setContainer(). It will be visible. It will also play any animation it possibly has. Also, audio media is started using this method.

If the media is not yet prefetched, it will first be prefetched.

Specified by:

play in interface XSmilesContentHandler

Overrides:

play in class BaseContentHandler

Throws:

java.lang.Exception

stop

public void stop()

Description copied from interface: XSmilesContentHandler

Stops the media. The media will be stopped and it will be invisible. Audio will be silent. It is possible to call start() after stop()

Specified by:

playPrimary

public void playPrimary()
                 throws java.lang.Exception

Throws:

java.lang.Exception

setContainer

public void setContainer(java.awt.Container container)

Sets the container the media will be rendered in. If media is audio, this can be null. Can be called if media is already visible in one container, it will then move to the new container.

Specified by:

setContainer in interface XSmilesContentHandler

Overrides:

setContainer in class BaseContentHandler

Parameters:

container - This container will contain the media.

close

public void close()

Description copied from interface: XSmilesContentHandler

This will freeze all memory and references to this media. If the media is not yet stopped, it will first be stopped. It is not possible to call start() after close() has been called.

Specified by:

Overrides:

close in class BaseContentHandler

setMediaTime

public void setMediaTime(int millisecs)

This moves the time position in media. Works only for continuous media (video/audio).

Specified by:

setMediaTime in interface XSmilesContentHandler

Overrides:

setMediaTime in class BaseContentHandler

Parameters:

millisecs - Time in millisecs

addMediaListener

public void addMediaListener(MediaListener listener)

Adds a MediaListener for this media. The listener will be called

1. When the media has been prefetched. (NOT IMPLEMENTED YET).
2. When the media ends. (continuous media, video/audio)

Static media, such as text and images will end immediately, notifying immediately about the end of media.

Overrides:

isStatic in class BaseContentHandler

Returns:

true if media is static (duration is zero, see getOriginalDuration().

getOriginalDuration

public int getOriginalDuration()

Get the duration of media. Only applicable for continuous media (audio, video).

Specified by:

getOriginalDuration in interface XSmilesContentHandler

Overrides:

getOriginalWidth

public int getOriginalWidth()

Get the real width of the media. If not visible, or size is unknown, then returns -1.

Specified by:
