public class CharRange
Define lexical character string range of values for ParameterSpace scheduling.
This class represents a set of strings which exist inclusively between an upper and lower boundary string. Strings within the range are ordered as follows:
1. Longer strings always appear after shorter strings.
For example, 'aaaa' appears after 'bbb'. This differs
from traditional dictionary order, but is more useful.
2. Strings of the same length are sorted in dictionary order,
according to the defined lexical order of the character set.
3. The lexical order of characters is determined by their
position in charSet
in the constructor.
4. Character orderings are case sensitive. Two characters
differing only by case (such as 'a' and 'A') have no
special relation to each other. They are completely
unique characters.
A typical use of this class is to define a range of character strings and split it up into many smaller subranges for parallel processing. The following is an example of this usage:
range = CharRange("ACGT", "", "TTTTTTT"); pspace = ParameterSpace() pspace.appendDimension("dna",range) pspace.setMaxJobletSize(10000) self.schedule(MyJoblet,pspace,())
The above code defines a string range consisting of all DNA sequences up to
length 7. Then adds the range to a ParameterSpace which sets the split up
(JobletSize) into unique subsets of 10000 sequences, and passes to schedule
to schedule the parallel processing.

public CharRange(java.lang.String charSet, java.lang.String first, java.lang.String last)
Defines a range of strings starting with first
and ending with last
. Longer strings are
"greater than" shorter strings, and lexical ordering among
equal-length strings is determined by the ordering of
characters in charSet
.
If last
is "greater than" first
then
the set is defined in reverse order, such that longer
strings appear first, and strings of the same length appear
in the reverse lexical order of that defined by charSet
.
charSet
- The character set over which the range is defined. Lexical
order of characters is determined by their position in this
string, with leftmost characters being ordered first.first
- The first string in the set.last
- The last string in the set.
Thrown
- if first
or last
contain
characters not in charSet
