# Class NioExtensions

java.lang.Object
org.codehaus.groovy.runtime.DefaultGroovyMethodsSupport
org.apache.groovy.nio.extensions.NioExtensions

public class NioExtensions extends DefaultGroovyMethodsSupport
This class defines new groovy methods for Readers, Writers, InputStreams and OutputStreams which appear on normal JDK classes inside the Groovy environment. Static methods are used with the first parameter being the destination class, i.e. `public static T eachLine(InputStream self, Closure c)` provides a `eachLine(Closure c)` method for `InputStream`.

NOTE: While this class contains many 'public' static methods, it is primarily regarded as an internal class (its internal package name suggests this also). We value backwards compatibility of these methods when used within Groovy but value less backwards compatibility at the Java method call level. I.e. future versions of Groovy may remove or move a method call in this file but would normally aim to keep the method available from within Groovy.

    public static void traverse(Path self, Map<String,Object> options, @ClosureParams(value=SimpleType.class,options="java.nio.file.Path") Closure closure) throws IOException
    Processes each descendant file in this directory and any subdirectories. 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:
      `self` - a Path (that happens to be a folder/directory)
      `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
    Throws:
      `FileNotFoundException` - if the given directory does not exist
      `IllegalArgumentException` - if the provided Path object does not represent a directory or illegal filter combinations are supplied
