  Parameters:
    `rootClasses` - the rootClasses to be used for this scan.

### getIncludedFiles

    public java.lang.String[] getIncludedFiles()

  Get the names of the class files on which baseClass depends.

  Specified by:
    `getIncludedFiles` in interface `FileScanner`
  Overrides:
    `getIncludedFiles` in class `DirectoryScanner`
  Returns:
    the names of the files.

### getIncludedFilesCount

    public int getIncludedFilesCount()

  Return the count of included files..

  Overrides:
    `getIncludedFilesCount` in class `DirectoryScanner`

    `int`.

### scan

    public void scan()
              throws java.lang.IllegalStateException

  Specified by:
    `scan` in interface `FileScanner`
  Overrides:
    `scan` in class `DirectoryScanner`

    `DirectoryScanner.slowScan()`

### setExcludes

    public void setExcludes(java.lang.String[] excludes)

  Set the list of exclude patterns to use. All '/' and '\' characters are replaced by `File.separatorChar`, so the separator used need not match `File.separatorChar`.

  When a pattern ends with a '/' or '\', "**" is appended..

  Specified by:
    `setExcludes` in interface `FileScanner`
  Overrides:
    `setExcludes` in class `DirectoryScanner`
  Parameters:
    `excludes` - A list of exclude patterns. May be `null`, indicating that no files should be excluded. If a non-`null` list is given, all elements must be non-`null`.

### setIncludes

    public void setIncludes(java.lang.String[] includes)

  Set the list of include patterns to use. All '/' and '\' characters are replaced by `File.separatorChar`, so the separator used need not match `File.separatorChar`.
