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.

Field Summary

static int	ALLOW_CACHE_READ For MediaContainer component objects, specifies that this object allows the reading of its cached flag.
static int	ALLOW_CACHE_WRITE For MediaContainer component objects, specifies that this object allows the writing of its cached flag.
static int	ALLOW_URL_READ For MediaContainer component objects, specifies that this object allows the reading of it's sound data.
static int	ALLOW_URL_WRITE For MediaContainer component objects, specifies that this object allows the writing of it's URL path.

Constructor Detail

MediaContainer

public MediaContainer()

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

URL String data : null
URL object data : null
InputStream data : null
cache enable : true

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:

Java 3D 1.2

setURLObject

public void setURLObject(java.net.URL url)

Set URL Object.

Parameters:
