Class TimestampSelector

  • All Implemented Interfaces:
    java.lang.Cloneable

    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.
