FormatControl

Fields Summary

Constructors Summary

Methods Summary
public javax.media.Format	getFormat() Obtain the format that this object is set to. return the current format.
public javax.media.Format[]	getSupportedFormats() Lists the possible input formats supported by this plug-in. return an array of the supported formats
public boolean	isEnabled() Return the state of the track. return A boolean telling whether or not the track is enabled.
public void	setEnabled(boolean enabled) Enable or disable the track. param enabled true if the track is to be enabled.
public javax.media.Format	setFormat(javax.media.Format format) Sets the data format. The method returns null if the format is not supported. Otherwise, it returns the format that's actually set. However in some situations, returning a non-null format does not necessarily mean that the format is supported since determining the supported formats may be state dependent or simply too costly. In such cases, the setFormat call will succeed but the object may fail in another state-transition operation such as when the object is being initialized. Alternatively, the getSupportedFormats method can be used to query for the list of supported formats. The resulting list can be used to screen for the valid formats before setting that on the object. return null if the format is not supported; otherwise return the format that's actually set.
