/* This class is a simple wrapper around a Java object to demonstrate
   writing to files.  The only real reason for this class is to provide a
   write[] method that always coerces the input value to a string.

   Note:  As of the 2012-02-06 release, this functionality is implemented as
   part of the Frink standard distribution.  The syntax is the same, but you
   don't need to include this file anymore.

   Example usage:

   use Writer.frink
   a = new Writer["writerout.txt"]
   a.write[2]
   a.writeln[" monkeys."]
   a.close[]
*/
class Writer
{
   // A Java FileWriter object.
   var fileWriter
   
   // Constructor to create a new writer, opening the specified file at the
   // same time.  If append is true, this will append to the file.
   new[path, append=false] :=
   {
      fileWriter = newJava["java.io.FileWriter", [path, append]]
   }

   // Writes the specified value, as a string, to the output.
   write[x] :=  fileWriter.write[toString[x]]

   // Writes the specified value, as a string, to the output, followed by
   // a carriage return.
   writeln[x] := fileWriter.write[toString[x] + "\n"]

   // Closes the file.
   close[] :=
   {
      fileWriter.close[]
      fileWriter = undef
   }
}
