public void <B>reset</B>(int&nbsp;primitive)</PRE>
<DL>
<DD>Removes all data from the GeometryInfo and resets the primitive.
 After a call to reset(), the GeometryInfo object will be just like
 it was when it was newly constructed.
<P>
<DD><DL>
<DT><B>Parameters:</B><DD><CODE>primitive</CODE> - Either TRIANGLE_ARRAY, QUAD_ARRAY,
 TRIANGLE_FAN_ARRAY, TRIANGLE_STRIP_ARRAY, or POLYGON_ARRAY.
 Tells the GeometryInfo object the type of primitive data to be stored
 in it, so it will know the format of the data.</DL>

<DT><B>Throws:</B>
<DD><CODE>java.lang.IllegalArgumentException</CODE> - if coordinate data is missing,
 if the index lists aren't all the
 same length, if an index list is set and the corresponding data
 list isn't set, if a data list is set and the corresponding
 index list is unset (unless all index lists are unset or in
 USE_COORD_INDEX_ONLY format),
 if StripCounts or ContourCounts is inconsistent with the current
 primitive, if the sum of the contourCounts array doesn't equal
 the length of the StripCounts array, or if the number of vertices
 isn't a multiple of three (for triangles) or four (for quads).</DL>
