## [Java] Class NioExtensions

- org.apache.groovy.nio.extensions.NioExtensions

- 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 eachDirMatch(Path self, Object nameFilter, @com.github.javaparser.ast.expr.NormalAnnotationExprClosureParams Closure closure)

      Invokes the closure for each subdirectory whose name (dir.name) matches the given nameFilter in the given directory - calling the DefaultGroovyMethods#isCase(java.lang.Object, java.lang.Object) method to determine if a match occurs. This method can be used with different kinds of filters like regular expressions, classes, ranges etc. Only subdirectories are matched; regular files are ignored.

      throws:
        java.io.FileNotFoundException if the given directory does not exist
      throws:
        IllegalArgumentException if the provided Path object does not represent a directory
      Parameters:

    - #### public static void traverse(Path self, Map<String, Object> options, @com.github.javaparser.ast.expr.NormalAnnotationExprClosureParams 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++ }

      throws:
        java.io.FileNotFoundException if the given directory does not exist
      throws:

      Parameters:

        2.3.0

    - #### public static T withWriterAppend(Path self, String charset, boolean writeBom, @com.github.javaparser.ast.expr.NormalAnnotationExprClosureParams Closure<T> closure)

      Create a new BufferedWriter which will append to this file. The writer is passed to the closure and will be closed before this method returns. The writer will use the given charset encoding. If the given charset is "UTF-16BE" or "UTF-16LE" (or an equivalent alias), `writeBom` is `true`, and the file doesn't already exist, the requisite byte order mark is written to the stream when the writer is created.

      throws:
        java.io.IOException if an IOException occurs.
      Parameters:
        `self` - a Path
        `charset` - the charset used
        `writeBom` - whether to write the BOM
        `closure` - a closure
      Returns:
        the value returned by the closure
      Since:
        2.5.0

    - #### public static T withWriterAppend(Path self, @com.github.javaparser.ast.expr.NormalAnnotationExprClosureParams Closure<T> closure)

      Create a new BufferedWriter for this file in append mode. The writer is passed to the closure and is closed after the closure returns. The writer will not write a BOM.

      throws:
        java.io.IOException if an IOException occurs.
      Parameters:
        `self` - a Path
        `closure` - a closure
      Returns:
        the value returned by the closure
      Since:
        2.3.0

    - #### public static void write(Path self, String text)

      Write the text to the Path without writing a BOM .

      throws:
        java.io.IOException if an IOException occurs.
      Parameters:
        `self` - a Path

      Since:
        2.3.0

    - #### public static void write(Path self, String text, boolean writeBom)

      Write the text to the Path. If the default charset is "UTF-16BE" or "UTF-16LE" (or an equivalent alias) and `writeBom` is `true`, the requisite byte order mark is written to the file before the text.

      throws:
        java.io.IOException if an IOException occurs.
      Parameters:
        `self` - a Path
        `text` - the text to write to the Path
        `writeBom` - whether to write the BOM
      Since:
        2.5.0
