Description Henning Schmiedehausen 2006-12-07 07:44:17 UTC 
FilterReader is another extension point of ant like the <typedef> and <taskdef>
tasks. So it would be good if a <filterreader> element could also loaded from a
specific classpath using a specific loader. 

e.g. the serialver.sf.net project offers a serialversion tool that also contains
a FilterReader. However, it is not possible to load the FilterReader from a
specified load path (like the task). 

It would be good to have this in 1.7.0 (IMHO).

Note that one can provide filtering
capability using the typedef task.
From the ant manual:
"""
package my.customant;
import org.apache.tools.ant.filters.TokenFilter;

public class Capitalize
    implements TokenFilter.Filter
{
    public String filter(String token) {
        if (token.length() == 0)
            return token;
        return token.substring(0, 1).toUpperCase() +
                token.substring(1);
   }
}
"""

"""
  <typedef type="capitalize" classname="my.customant.Capitalize"
           classpath="my.customant.path"/>
  <copy file="input" tofile="output">
    <filterchain>
      <tokenfilter>
        <stringtokenizer/>
        <capitalize/>
      </tokenfilter>
    </filterchain>
  </copy>
