Create macro with Java - Execute Script Operator


Create macro with Java - Execute Script Operator



I wish to create macro starting from an object in java in Execute Script operator. In my example, I recover the date of a file and I wish to use it thereafter as macro in my RapidMiner process. I don't know how to exit this object of the Execute Script operator in the form of macro.


LastDate = Files.getLastModifiedTime(Paths.get("%{Way}")) ;

// and after ?

If not I had found an alternative by creating a table and while inserting the date inside. But I did not succeed in inserting this date in table.

(I am to help with this post)


LastDate = Files.getLastModifiedTime(Paths.get("%{Way}")) 

// create a table
MemoryExampleTable table = new MemoryExampleTable();

// create and add attributes
nominalAttr = AttributeFactory.createAttribute("File", Ontology.NOMINAL);
dateAttr = AttributeFactory.createAttribute("Last_Modify",Ontology.DATE_TIME);


// create a data row DataRow row = new DoubleSparseArrayDataRow(); row.set(nominalAttr, nominalAttr.getMapping().mapString("%{file_name}")); row.set(dateAttr, LastDate); // add the row to the table table.addDataRow(row); // create an ExampleSet from the underlying table ExampleSet exampleSet = table.createExampleSet(); return exampleSet;


I am really thankful for every help from you
