- All Implemented Interfaces:
- ResourceFactory
 
 public class SourceFileScanner extends java.lang.Object implements ResourceFactory Utility class that collects the functionality of the various scanDir methods that have been scattered in several tasks before.The only method returns an array of source files. The array is a subset of the files given as a parameter and holds only those that are newer than their corresponding target files.

Method Detail- 
restrictpublic java.lang.String[] restrict(java.lang.String[] files, java.io.File srcDir, java.io.File destDir, FileNameMapper mapper)Restrict the given set of files to those that are newer than their corresponding target files.- Parameters:
- files- the original set of files.
- srcDir- all files are relative to this directory.
- destDir- target files live here. if null file names returned by the mapper are assumed to be absolute.
- mapper- knows how to construct a target file names from source file names.
- Returns:
- an array of filenames.

- granularity- The number of milliseconds leeway to give before deciding a target is out of date.
- Returns:
- an array of filenames.
- Since:
- Ant 1.6.2
