public class IOGroovyMethods
extends DefaultGroovyMethodsSupport

This class defines new groovy methods for Files, URLs, URIs 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 long size(File self) provides a size() method for File.

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.

For each line, the given closure is called with a single parameter being the list of strings computed by splitting the line around matches of the given regular expression. The Reader is closed afterwards.
  Here is an example:
  def s = 'The 3 quick\nbrown 4 fox' def result = '' new StringReader(s).splitEachLine(~/\d/){ parts -> result += "${parts[0]}_${parts[1]}|" } assert result == 'The _ quick|brown _ fox|'
  Parameters:
  
  self - a Reader, closed after the method returns
  
  pattern - the regular expression Pattern for the delimiter
  
  closure - a closure
  
  Returns:

- readLine
  
  public static java.lang.String readLine(java.io.Reader self) throws java.io.IOException
  
  Read a single, whole line from the given Reader. This method is designed for use with Readers that support the mark() operation like BufferReader. It has a fallback behavior for Readers that don't support mark() but the behavior doesn't correctly detect multi-character line termination (e.g. carriage return followed by linefeed). We recommend for Readers that don't support mark() you consider using one of the following methods instead: eachLine, readLines, or iterator.
  
  Parameters:
  
  self - a Reader
  
  Returns:
  
  a line
  
  Throws:
  
  java.io.IOException - if an IOException occurs.
