usePresentationFileSystem

Type:  Boolean

Default Value: True

The usePresentationFileSystem property of the MultiMediaType class specifies whether the Sound class loadFromFile method is processed on the application server or presentation client when the receiver is running in JADE thin client mode.

If you are not running in JADE thin client mode, the value of this property has no effect.

This property is set to true by default, when running in JADE thin client mode. Set this property to false to cause the file system where the application server is running to be used when running the application in JADE thin client mode.

Any change to this property is ignored if the file has already been opened.

The Sound class loadFromFile method is processed on the presentation client when the MultiMediaType class usePresentationFileSystem property is set to true, including shared transient instances of the Sound class. The loadFromFile method loads the data from the file into the object, which can then be played by any user of that object.

Although a file opened on one presentation client cannot be accessed by another client, as the file access occurs only on the load (which could be from the presentation client), that file is not used thereafter.
