Class TimestampSelector

java.lang.Object
  org.apache.tools.ant.ProjectComponent
      org.apache.tools.ant.Task
          net.sf.antcontrib.logic.TimestampSelector

public class TimestampSelector
extends org.apache.tools.ant.Task

Task definition for the foreach task. The foreach task iterates over a list, a list of filesets, or both.

 Usage:

   Task declaration in the project:
   
     <taskdef name="latesttimestamp" classname="net.sf.antcontrib.logic.TimestampSelector" />
   

   Call Syntax:
   
     <timestampselector
                 [property="prop" | outputsetref="id"]
                 [count="num"]
                 [age="eldest|youngest"]
                 [pathSep=","]
                 [pathref="ref"] >
       <path>
          ...
       </path>
     </latesttimestamp>
   

   Attributes:
         outputsetref --> The reference of the output Path set which will contain the
                          files with the latest timestamps.
         property  --> The name of the property to set with file having the latest
                       timestamp.  If you specify the "count" attribute, you will get
                       the lastest N files.  These will be the absolute pathnames
         count     --> How many of the latest files do you wish to find
         pathSep   --> What to use as the path separator when using the "property"
                       attribute, in conjunction with the "count" attribute
         pathref   --> The reference of the path which is the input set of files.
