Class SimpleFilePattern

java.lang.Object

eu.bandm.tools.util.SimpleFilePattern

public class SimpleFilePattern
extends Object

Maps an input file name to an output file name according to a very simple pattern rule inspired by "patsubst" from "make". A SimpleFilePattern is constructed giving two(2) Strings which contain exactly one(1) place holder character. Then it is applied to some input String, yielding the output String.

  patterns   =    inpre%inpost 
                  outpre%outpost
  inputname  =   XXXXinpreYYYYinpost
       (with inpost = latest occurence of inpost, inpattern must even END WITH inpost.
        inpre  = latest occurrence in inpattern, before inpost)
  outputname =   XXXXoutpreYYYYoutpost
  stem       =             YYYY
  

// ?????? inpre or outpre may be empty, but not both.
As a variant, there is the case "multiple=false", in which neither of the Strings contains a place holder character. In this case the input must be identical with the first string to yield the second.
LATER a variant with an additional variable suffix could be sensible:

  inputname  =   XXXXinpreYYYYinpostZZZZ 
       (with inpost = latest occurence of, inpre  = latest occurrence before inpost)
  outputname =   XXXXoutpreYYYYoutpostZZZZ
