Class FileRange

All Implemented Interfaces:

java.io.Serializable

public class FileRange
extends org.python.core.PySequence

Define a range of values for a ParameterSpace based on the lines of a text file. An instance of this class is used as a dimension in a ParameterSpace definition.

The file name must either refer to a file that is readable from the server and resources (on a shared file system) or must be a DataGrid file URL.

Example to distribute each line of a text file residing on a shared filesystem to a Joblet:

 class myjob(Job):
     def job_started_event(self):
        fr = FileRange("/mytests/testlist")
        fr.setSkipBlankLines(True)
        parameterSpace = ParameterSpace()
        parameterSpace.appendDimension("testlist",fr)
        # Setting JobletSize to 1 creates one Joblet per line
        parameterSpace.setMaxJobletSize(1)
        self.schedule(myJoblet,parameterSpace)
 

In the above example, only a single dimension is defined. So each line of the source text file makes up a single row in the ParameterSpace.

Example of how the created JobletParameterSpace is used in a Joblet:

 class myJoblet(Joblet):
      def joblet_started_event(self):
         parameterSpace = self.getParameterSpace()
         while parameterSpace.hasNext():
              row = parameterSpace.next()
              element = row["testlist"]
              print "element=%s" % (element)
