All Implemented Interfaces:

ParallelSpaceModel

public class STFDataSet

extends SimpleParallelSpaceModel

A Simple file parser for reading STF (Simple Table Fomrat) files from URLs. The STF File format is defined as follows:

# test.stf
# Comments have # in the first column.
# Type the number of fields, on a line by itself.
3
# Then type field names and types. Field names must not contain
# spaces.
#
PersonName     String
Age            Integer
HourlyWage     Real
#
# Data type is case-insensitive.
# Default data delimiters are tabs and spaces.
# Here's the data, tab-delimited. Notice that the data columns are
# in the order they are listed above.
#
Joe            23      5.75
Mary           18      4.75
Fred           54      100.00
Ginger         48      100.00
#
# Nothing special is required to end the file.

Once the file is read and parsed, the data can be accessed with the methods defined in the ParallelSpaceModel interface.
