FloatRefValues

• java.lang.Object

Fields Summary
FloatSegment[]	segments This RefValues FloatSegments.
float[]	w A working array to return a value from the compute method.
float	length Used to store the length of this RefValues
float[]	segLength Used to store the length of each segment.

Constructors Summary

Methods Summary
public java.lang.Object[]	compute(int si, float p) Computes the value for the input interpolated values. There should be as many entries in the return array as there are components in the RefValues. param si the current segment index param p the current penetration segments[si].compute(p, w); return w;
public int	getComponents() FloatRefValues only have one component. This returns the number of components in the start value of the first segment. return the number of components. There is an array of float for each component. return segments[0].start.length;
public float	getLength() Computes the length of the RefValues. This is meant for paced timing computation. return the total length of this FloatRefValues. The distance is defined as the average distance between r return length;
public float	getLength(int si) Computes the length of segment at index si param si the segment index. return segLength[si];
public Segment	getSegment(int i) param i requested segment index. return Segment at index i return segments[i];
public int	getSegments() return the number of segments in refValues return segments.length;
public void	initialize() Should be called after the RefValue's configuration is complete to give the implementation a chance to initialize internal data and cache values. // Initialize the working buffer final int nc = segments[0].start.length; w = new float[nc][]; final int ns = segments.length; // Initialize the segments. for (int si = 0; si < ns; si++) { segments[si].initialize(); } segLength = new float[ns]; // The length of a FloatSegment, is the average distance between each // component. for (int ci = 0; ci < nc; ci++) { w[ci] = new float[segments[0].start[ci].length]; } length = 0; for (int si = 0; si < ns; si++) { segLength[si] = segments[si].getLength(); length += segLength[si]; }
public void	makeDiscrete() Adds a new time segment so accomodate for discreet behavior. If there is only one segment for discreet animations, the last value is never shown. To accomodate for that, this method should add a segment to the RefValues so that the last animation value is shown during the last value interval of a discreet animation. FloatSegment[] tmpSegments = new FloatSegment[segments.length + 1]; System.arraycopy(segments, 0, tmpSegments, 0, segments.length); FloatSegment lastSeg = segments[segments.length - 1]; FloatSegment newSeg = new FloatSegment(); newSeg.start = lastSeg.end; newSeg.end = lastSeg.end; tmpSegments[tmpSegments.length - 1] = newSeg; segments = tmpSegments;
public java.lang.String	toString() Debug helper. StringBuffer sb = new StringBuffer(); sb.append("FloatRefValues[" + getSegments() + "]\n"); for (int si = 0; si < getSegments(); si++) { Segment seg = getSegment(si); sb.append("seg[" + si + "] : " + seg.toString() + "\n"); } return sb.toString();
