loop replace mapper

[Patrick Martin]

Hello,

I wrote a small mapper which loops on a string list and replaces a
token in the input file name.
it can be used (since ant 1.8.1) like this:
                <copy todir="test/data/destdir" enablemultiplemappings="true">
                        <fileset dir="test/data/srcdir" includes="**" />
                        <loopreplacemapper token="@dirname@" list="dir1,dir2" />
                </copy>
                <zip destfile="test/data/destzip.zip">
                        <mappedresources enablemultiplemappings="true">
                                <fileset dir="test/data/srcdir" includes="**" />
                                <loopreplacemapper token="@dirname@" 
list="dir1,dir2" />
                        </mappedresources>
               </zip>

Would this fit in the next standard ant version ?

Here is the source code:

public class LoopReplaceMapper implements FileNameMapper {
        private String token;
        private ArrayList<String> list;

        public void setToken(String token) {
                this.token = token;
        }

        public String getToken() {
                return token;
        }

        public void setList(String _list) {
                StringTokenizer st = new StringTokenizer(_list, "       , ");
                this.list = new ArrayList<String>(st.countTokens());
                while (st.hasMoreTokens()) {
                        list.add(st.nextToken());
                }
        }

        public String getList() {
                return list.toString();
        }

        public String[] mapFileName(String sourceFileName) {
                String[] mappedFileNames = null;
                if (sourceFileName.contains(getToken())) {
                        mappedFileNames = new String[list.size()];
                        int index = 0;
                        for (String replacement : list) {
                                mappedFileNames[index++] = 
sourceFileName.replace(getToken(), replacement);
                        }
                } else {
                        mappedFileNames = new String[1];
                        mappedFileNames[0] = sourceFileName;
                }
                return mappedFileNames;
        }

        public void setFrom(String from) {
        }

        public void setTo(String to) {
        }
}

 Rgds,
