      Since:
        2.3.0
      See Also:
        Path#traverse(java.util.Map, groovy.lang.Closure)

    - #### public void traverse(Map options, Closure closure)

      Processes each descendant file in this directory and any sub-directories. Processing consists of potentially calling `closure` passing it the current file (which may be a normal file or subdirectory) and then if a subdirectory was encountered, recursively processing the subdirectory.

      The traversal can be adapted by providing various options in the `options` Map according to the following keys:

      type
        A FileType enum to determine if normal files or directories or both are processed
      preDir
        A Closure run before each directory is processed and optionally returning a FileVisitResult value which can be used to control subsequent processing.
      preRoot
        A boolean indicating that the 'preDir' closure should be applied at the root level
      postDir
        A Closure run after each directory is processed and optionally returning a FileVisitResult value which can be used to control subsequent processing.
      postRoot
        A boolean indicating that the 'postDir' closure should be applied at the root level
      visitRoot
        A boolean indicating that the given closure should be applied for the root dir (not applicable if the 'type' is set to FileType#FILES)
      maxDepth
        The maximum number of directory levels when recursing (default is -1 which means infinite, set to 0 for no recursion)
      filter
        A filter to perform on traversed files/directories (using the DefaultGroovyMethods#isCase(Object, Object) method). If set, only files/dirs which match are candidates for visiting.
      nameFilter
        A filter to perform on the name of traversed files/directories (using the DefaultGroovyMethods#isCase(Object, Object) method). If set, only files/dirs which match are candidates for visiting. (Must not be set if 'filter' is set)
      excludeFilter
        A filter to perform on traversed files/directories (using the DefaultGroovyMethods#isCase(Object, Object) method). If set, any candidates which match won't be visited.
      excludeNameFilter
        A filter to perform on the names of traversed files/directories (using the DefaultGroovyMethods#isCase(Object, Object) method). If set, any candidates which match won't be visited. (Must not be set if 'excludeFilter' is set)
      sort
        A Closure which if set causes the files and subdirectories for each directory to be processed in sorted order. Note that even when processing only files, the order of visited subdirectories will be affected by this parameter.
      This example prints out file counts and size aggregates for groovy source files within a directory tree:

          def totalSize = 0
          def count = 0
          def sortByTypeThenName = { a, b ->
              a.isFile() != b.isFile() ? a.isFile() <=> b.isFile() : a.name <=> b.name
          }
          rootDir.traverse(
                  type         : FILES,
                  nameFilter   : ~/.*\.groovy/,
                  preDir       : { if (it.name == '.svn') return SKIP_SUBTREE },
                  postDir      : { println "Found $count files in $it.name totalling $totalSize bytes"
                                  totalSize = 0; count = 0 },
                  postRoot     : true
                  sort         : sortByTypeThenName
          ) {it -> totalSize += it.size(); count++ }

      Parameters:
        `options` - a Map of options to alter the traversal behavior
        `closure` - the Closure to invoke on each file/directory and optionally returning a FileVisitResult value which can be used to control subsequent processing
