Examples of ptolemy.data.ArrayToken

ptolemy.data.ArrayToken
A token that contains an array of tokens. The operations between arrays are defined pointwise, and require that the lengths of the arrays are the same. The elements of the ArrayToken will be converted to the least upper bound of their input types. Zero length array tokens are supported, given a prototype element to determine the type of the array. @author Yuhong Xiong, Steve Neuendorffer, Contributor: Christopher Brooks @version $Id: ArrayToken.java,v 1.119 2007/12/07 06:31:43 cxh Exp $ @since Ptolemy II 0.4 @Pt.ProposedRating Yellow (cxh) @Pt.AcceptedRating Red (cxh) nil token code
