Constructor Detail

LwsEnvelope

LwsEnvelope(java.io.StreamTokenizer st,
           int frames,
           float time)

Constructor: calls getEnvelope() to parse the stream for the envelope data

Method Detail

getEnvelope

void getEnvelope(java.io.StreamTokenizer st)
           throws IncorrectFormatException,
                  ParsingErrorException

Parses the stream to retrieve all envelope data. Creates LwsEnvelopeFrame objects for each keyframe of the envelope (these frames differ slightly from LwsFrame objects because envelopes contain slightly different data)

Throws:

IncorrectFormatException

ParsingErrorException

createJava3dBehaviors

void createJava3dBehaviors(TransformGroup target)

This superclass does nothing here - if the loader understands how to deal with a particular type of envelope, it will use a subclass of LwsEnvelope that will override this method

getBehaviors

Behavior getBehaviors()

getFirstFrame

LwsEnvelopeFrame getFirstFrame()

printVals

void printVals()
