ProcessorModel

• java.lang.Object

Fields Summary
private Format[]	formats
private MediaLocator	inputLocator
private DataSource	inputDataSource
private ContentDescriptor	outputContentDescriptor

Constructors Summary
public ProcessorModel() Creates a ProcessorModel with null properties. // Nothing to do
public ProcessorModel(Format[] formats, ContentDescriptor outputContentDescriptor) Creates a ProcessorModel for the specified track formats and output content-type. This constructor creates a ProcessorModel that can be used to construct a Processor for capturing media data. param formats An array of Format objects that contains the desired track formats. param outputContentDescriptor A ContentDescriptor that describes the desired output content-type. return A ProcessorModel that encapsulates the specified attributes. this.outputContentDescriptor = outputContentDescriptor; this.formats = formats;
public ProcessorModel(DataSource inputDataSource, Format[] formats, ContentDescriptor outputContentDescriptor) Creates a ProcessorModel for the specified input DataSource, track formats, and output type. param inputDataSource The DataSource that identifies the media source for the ProcessorModel. param formats An array of Format objects that contains the desired track formats. param outputContentDescriptor A ContentDescriptor that describes the desired output content-type. return A ProcessorModel that encapsulates the specified attributes. this.inputDataSource = inputDataSource; this.formats = formats; this.outputContentDescriptor = outputContentDescriptor;
public ProcessorModel(MediaLocator inputLocator, Format[] formats, ContentDescriptor outputContentDescriptor) Creates a ProcessorModel for the specified input MediaLocator, track formats, and output type. param inputLocator The MediaLocator that identifies the media source for this ProcessorModel. param formats An array of Format objects that contains the desired track formats. param outputContentDescriptor A ContentDescriptor that describes the desired output content-type. return A ProcessorModel that encapsulates the specified attributes. this.inputLocator = inputLocator; this.formats = formats; this.outputContentDescriptor = outputContentDescriptor;

Methods Summary
public javax.media.protocol.ContentDescriptor	getContentDescriptor() Gets the output content-type specified by this ProcessorModel. return A ContentDescriptor that defines the output content-type. Returns null if the output type is not applicable or the output streams are to contain raw data that doesn't pertain to a specific content-type. return outputContentDescriptor;
public javax.media.protocol.DataSource	getInputDataSource() Gets the input DataSource that specifies the media source for this ProcessorModel. The inputLocator is ignored if this value is non-null. return A DataSource that specifies the media source. return inputDataSource;
public javax.media.MediaLocator	getInputLocator() Gets the input MediaLocator that specifies the media source for this ProcessorModel. This value is ignored if an input DataSource is specified. return A MediaLocator that specifies the media source. return inputLocator;
public javax.media.Format	getOutputTrackFormat(int tIndex) Gets the preferred Format of the specified track. param tIndex The index of the track for which you want to get the preferred Format. return The preferred Format for the track. if (formats != null && formats.length > tIndex) return formats[tIndex]; return null;
public int	getTrackCount(int availableTrackCount) Gets the number of tracks required as the output of the Processor constructed with this ProcessorModel. param availableTrackCount The number of tracks available, as an integer. return The number of tracks required, as an integer. if (formats != null) return formats.length; return -1;
public boolean	isFormatAcceptable(int tIndex, javax.media.Format tFormat) Checks whether or not tFormat is an acceptable format for the track tIndex. param tIndex The index of the track you want to check. param tFormat The Format to check. return true if the Format is acceptable, otherwise returns false. if (formats != null && formats.length > tIndex) { if (tFormat.matches(formats[tIndex])) return true; else return false; } return true;
