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.
FileRange(String filename): Constructs a FileRange using the supplied filename. The file must be readable.
Parameters: The userenv - true to set user environment variables.
Define the line delimiter to separate lines. Defaults to line feed.
Parameters: delimiter - Character to use for delimiting lines.
Defines whether to ignore blank lines or not. Default is to not ignore blank lines.
Parameters: delimiter - Character to use for delimiting lines.

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 example above, only a single dimension is defined. So each line of the source text file makes up a single row in the ParameterSpace.
class myJoblet(Joblet):
def joblet_started_event(self):
parameterSpace = self.getParameterSpace()
while parameterSpace.hasNext():
row = parameterSpace.next()
element = row["testlist"]
print "element=%s" % (element)
