[BM Import] TOOL Compile error in CodeBlock

Question

Hi,
One of the users tries to import XXXBM.pex in a workspace where there is
AppModel, Forte Express 3.0.G.2 and XXXBMServices.pex
While importing, it's got the following error:
Erros in Codeblock:
726 An object constructor for the class AppModel.abConnection contains
an unnamed clause.
All the clauses in an object constructor must be of the form
'name = expression'
It occurs 4 times
'Code Block in import file will not be run because of errors
I don't know what codeblock is, nor what a clause is.
Any suggestion ?
Thanks,

Answer 1

class FileStream extends AdjMatrix {
     double answer;
     String line;
     AdjMatrix theMatrix;
     int total;
     public FileStream(String fileName) {
          Since you don't specify which constructor of AdjMatrix to use in the contruction of FileStream the compiler is trying to use the default constructor of AdjMatrix BUT you don't have one!
Possible solutions -
1) Define a default constructor in AdjMatrix.
2) Use the public AdjMatrix(int num_vertices) constructor by using
     public FileStream(String fileName) {
             super(10); // or what ever size you think is appropriate3) Change AdjMatrix to use so as to use dynamic arrays (ArrayList?) instead of having a fixed dimension.
4) MakeFile stream a factory that does not extend AdjMatrix but has a method that returns an AdjMatrix based on a filename argument.
e.g.
class  FileStreamFactory
     public AdjMatrix createFromFile(String filename)
             // Parse the file to get the size
            AdjMatrix theMatrix = new AdMatrix(the size you parsed);
            // Fill in anything else you need to
            return  theMatrix ;
}You would use this by creating a factory and then using it to create your AdjMatrix.
It should be obvious that I prefer approach 4.
Have fun!
