Method Details- 
setTargetdirThe name of the file or directory which is checked for out-of-date files.- Parameters:
- targetdir- the directory to scan looking for files.
 
- 
createMapperDefines the FileNameMapper to use (nested mapper element).- Returns:
- a mapper to be configured
- Throws:
- BuildException- if more than one mapper defined
 
- 
addConfiguredAdd a configured FileNameMapper instance.- Parameters:
- fileNameMapper- the FileNameMapper to add
- Throws:
- BuildException- if more than one mapper defined
- Since:
- Ant 1.8.0

verifySettingspublic void verifySettings()Checks to make sure all settings are kosher. In this case, it means that the dest attribute has been set and we have a mapper.- Overrides:
- verifySettingsin class- BaseSelector
 
- 
isSelectedThe heart of the matter. This is where the selector gets to decide on the inclusion of a file in a particular fileset.- Specified by:
- isSelectedin interface- FileSelector
- Specified by:
- isSelectedin class- BaseSelector
- Parameters:
- basedir- the base directory the scan is being done from
- filename- is the name of the file to check
- file- is a java.io.File object the selector can use
- Returns:
- whether the file should be selected or not

setGranularitypublic void setGranularity(int granularity) Sets the number of milliseconds leeway we will give before we consider a file out of date. Defaults to 2000 on MS-DOS derivatives and 1000 on others.- Parameters:
- granularity- the leeway in milliseconds
