public class MediaContainer
extends NodeComponent

The MediaContainer object defines all sound data: cached state flag, and associated sound media. Currently this references the sound media in one of three forms: URL String, URL object, or InputStream object. In future releases media data will include references to Java Media Player objects. Only one type of sound media data specified using setURLString, setURLObject, or setInputStream may be non-null (or they may all be null). An attempt to set more than one of these attributes to a non-null reference will result in an exception being thrown. If all sound media data references are null, there is no sound associated with this MediaContainer and Sound nodes referencing this object cannot be played.

Constructor Detail

MediaContainer

public MediaContainer()
Constructs a MediaContainer object with default parameters. The default values are as follows:


MediaContainer

public MediaContainer(java.lang.String path)
Constructs and initializes a MediaContainer object using specified parameters.

Parameters:
path - string of URL path containing sound data
Throws:
SoundException - if the URL is not valid or cannot be opened

MediaContainer

public MediaContainer(java.net.URL url)
Constructs and initializes a MediaContainer object using specified parameters.

Parameters:
url - URL path containing sound data
Throws:
SoundException - if the URL is not valid or cannot be opened

MediaContainer

public MediaContainer(java.io.InputStream stream)
Constructs and initializes a MediaContainer object using specified parameters.

Parameters:
stream - input stream containing sound data
Since:
Java 3D 1.2
Method Detail

setCacheEnable

public void setCacheEnable(boolean flag)
Set Cache Enable state flag. Allows the writing of sound data explicitly into the MediaContainer rather than just referencing a JavaMedia container.

Parameters:
flag - boolean denoting if sound data is cached in this instance
Throws:
CapabilityNotSetException - if appropriate capability is not set and this object is part of live or compiled scene graph

getCacheEnable

public boolean getCacheEnable()
Retrieve Cache Enable state flag.

Returns:
flag denoting is sound data is non-cached or cached
Throws:
CapabilityNotSetException - if appropriate capability is not set and this object is part of live or compiled scene graph

setURL

public void setURL(java.lang.String path)
Deprecated. As of Java 3D version 1.2, replaced by setURLString


setURL

public void setURL(java.net.URL url)
Deprecated. As of Java 3D version 1.2, replaced by setURLObject


setURLString

public void setURLString(java.lang.String path)
Set URL String.

Parameters:
path - string of URL containing sound data
Throws:
CapabilityNotSetException - if appropriate capability is not set and this object is part of live or compiled scene graph
SoundException - if the URL is not valid or cannot be opened
java.lang.IllegalArgumentException - if the specified sound data is non-null and any other sound data reference is also non-null.
Since:
