10. presented so far we have always used a specific class routine to perform the operation However there are many cases where different classes may 23 of 42 perform the operation in different ways An example is the PLOT method which we have already come across in the 2D class There is also a PLOT method in the 1D class and in the POL2D class We can therefore make programs more general by first determining the class of the object and then call the appropriate CLA_ routine for that class This is a sufficiently common operation that a standard routine is provided This routine is CLA_GENER the generic class routine It has exactly the same calling sequence as any of the CLA_ routines but is not strictly a class To make our original IMDISP program more general we can simply replace the call to CLA_2D to a call to CLA GENER as follows CALL CLA_GENER OBJECT PLOT ARGS STATUS This will enable IMDISP to plot one dimensional data and polarization data as well as 2D images Moreover it means that in the future IMDISP will automatically acquire the ability to plot objects of any new class added to the class library provided the class has a PLOT method provided CLA_GENER determines the class of an object in one of three ways It first looks for the presence of an NDF_CLASS extension within the object If this is present the NAME component contained in this extension specifies the class name If no NDF_CLASS extension is

37. r which the subroutine is CLA_NDF and the 2D class with subroutine CLA_2D The term class refers to the class of data object on which the methods can operate Thus class NDF contains those operations which can be applied generally to any NDF object Class 2D contains those operations which apply to 2 dimensional data objects Classes are organized into a hierarchical structure with the most general class NDF at its root An illustration of the class hierarchy of the library is given below NDF POL POL2D Classes inherit all the methods of the classes below them in the hierarchy Thus all the methods of the NDF class are available to any class in the hierarchy The way this works in practice is a call to CLA_2D specifying a method such as ARITHMETIC which is a method of the NDF base class will always be valid What will happen is that CLA_2D will call CLA_NDF to handle the method In some cases it may be necessary for the derived class to override the method of the base class and 20 of 42 provide its own handling of an operation For example the ARITHMETIC method of the POL polarization class would have to handle the Stokes parameters as well as the main data array 5 4 Arithmetic Operations The ARITHMETIC method of the NDF class handles the basic arithmetic operations addition subtraction multiplication and division These operations are not quite as straightforward as you might think and the packaged arithmetic
