PacketDescriptor

public PacketDescriptor(org.w3c.dom.Element element)
                 throws StreamException

Creates a new instance of StreamProperties

Throws:

StreamException

PacketDescriptor

public PacketDescriptor()

Method Detail

getXDescriptor

public StreamXDescriptor getXDescriptor()

setXDescriptor

public void setXDescriptor(StreamXDescriptor x)

addYDescriptor

public void addYDescriptor(SkeletonDescriptor y)

getYCount

public int getYCount()

getYDescriptors

public java.util.List getYDescriptors()

Returns a List of SkeletonDescriptor instances that represent the y planes in a packet. The List is unmodifiable and will throw an exception if any attempt is made to alter the list. The contents of the list will not be updated if a yDescriptor is added to this packet descriptor.
