NioExtensions (groovy 3.0.19 API)

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.

    Invokes the closure for each 'child' file in this 'parent' folder/directory. Both regular files and subfolders/subdirectories are processed.
    throws:
    java.io.FileNotFoundException if the given directory does not exist
    throws:
    IllegalArgumentException if the provided Path object does not represent a directory
    
    Parameters:
    self - a Path (that happens to be a folder/directory)

  - public static void eachFileMatch(Path self, FileType fileType, Object nameFilter, @ClosureParams(value = SimpleType.class, options = "java.nio.file.Path") Closure closure)
    
    Invokes the closure for each file whose name (file.name) matches the given nameFilter in the given directory - calling the DefaultGroovyMethods.isCase method to determine if a match occurs. This method can be used with different kinds of filters like regular expressions, classes, ranges etc. Both regular files and subdirectories may be candidates for matching depending on the value of fileType.
```
 // collect names of files in baseDir matching supplied regex pattern
 import static groovy.io.FileType.*
 def names = []
 baseDir.eachFileMatch FILES, ~/foo\d\.txt/, { names << it.name }
 assert names == ['foo1.txt', 'foo2.txt']

 // remove all *.bak files in baseDir
 baseDir.eachFileMatch FILES, ~/.*\.bak/, { Path bak -> bak.delete() }

 // print out files > 4K in size from baseDir
 baseDir.eachFileMatch FILES, { new Path(baseDir, it).size() > 4096 }, { println "$it.name ${it.size()}" }

  - <T> public static T splitEachLine(Path self, Pattern pattern, String charset, @ClosureParams(value = FromString.class, options = {"List", "String[]"}, conflictResolutionStrategy = PickFirstResolver.class) Closure<T> closure)

Finally the resources used for processing the file are closed.
    throws:
    java.io.IOException if an IOException occurs.
    
    Parameters:
    self - a Path
    pattern - the regular expression Pattern for the delimiter
    charset - opens the file with a specified charset
    closure - a closure
    Returns:
    the last value returned by the closure

    Since:
    2.3.0
  - public static void traverse(Path self, Map<String, Object> options, @ClosureParams(value = SimpleType.class, options = "java.nio.file.Path") 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 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 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 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 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++ }
 
```
