ptolemy.data.ScalarToken
Abstract base class for tokens that contain a scalar. This base class extends the Token class to properly implement type conversion and the units portion of the standard operations for scalar tokens. It also adds methods for querying the natural ordering between scalars.
This class has a number of protected abstract methods that subclasses must implement. These methods need only implement the numerical portion of the operation between two tokens of the same type. This base class will handle the conversion of tokens from different types to the same type before calling the protected method, and the proper computation of the units of the returned token afterwards.
In general, any instance of a scalar token may be optionally associated with a set of units. In the arithmetic methods add(), modulo(), and subtract(), the two operands must have the same units. Otherwise, an exception will be thrown. In the methods multiply() and divide(), the units of the resulting token will be computed automatically. IMPORTANT: The protected methods implemented in derived classes are expected to return a new token in the case of multiply and divide. This new token will automatically have its units set correctly by this base class implementation. Certain cases, such as multiplication by one, cannot be optimized to simply return an the input token without performing the multiplication, since the units of the result may be different than the units of either input token. @author Yuhong Xiong, Mudit Goel, Steve Neuendorffer @version $Id: ScalarToken.java,v 1.116 2008/01/24 00:33:57 cxh Exp $ @since Ptolemy II 0.2 @Pt.ProposedRating Green (neuendor) @Pt.AcceptedRating Green (yuhong)
