Class StringListParser

java.lang.Object
  peersim.util.StringListParser

public class StringListParser
extends java.lang.Object

This utility class can be used to parse range expressions. In particular, it is used by RangeSimulator to express ranges for configuration properties.

The language for range expression is the following:

   [rangelist] := [range] | [range],[rangelist]
   [range] := value | min:max | min:max|step | 
      min:max*|step
 

where value, min, max and step are numeric atoms that defines ranges.

For example, the following range expression:

   5,9:11,13:17|2,32:128*|2
 

corresponds to 5 (single value), 9-10-11 (range between 9 and 11, default increment 1), 13-15-17 (range between 13 and 17, specified step 2, 32-64-128 (range between 32 and 128, multiplicative step 2).
