Obtains a lock, runs the block, and releases the lock when the block completes. See the example under Mutex.

Passes each character in str to the given block, or returns an enumerator if no block is given.

"hello".each_char {|c| print c, ' ' }

produces:

h e l l o

Calls the block once for each entry except for “.” and “..” in the named directory, passing the filename of each entry as a parameter to the block.

If no block is given, an enumerator is returned instead.

Dir.each_child("testdir") {|x| puts "Got #{x}" }

produces:

Got config.h
Got main.rb

Calls the block once for each entry except for “.” and “..” in this directory, passing the filename of each entry as a parameter to the block.

If no block is given, an enumerator is returned instead.

d = Dir.new("testdir")
d.each_child  {|x| puts "Got #{x}" }

produces:

Got config.h
Got main.rb

Calls the given block once for each character in ios, passing the character as an argument. The stream must be opened for reading or an IOError will be raised.

If no block is given, an enumerator is returned instead.

f = File.new("testfile")
f.each_char {|c| print c, ' ' }   #=> #<File:testfile>

Iterates over the children of the directory (files and subdirectories, not recursive).

It yields Pathname object for each child.

By default, the yielded pathnames will have enough information to access the files.

If you set with_directory to false, then the returned pathnames will contain the filename only.

Pathname("/usr/local").each_child {|f| p f }
#=> #<Pathname:/usr/local/share>
#   #<Pathname:/usr/local/bin>
#   #<Pathname:/usr/local/games>
#   #<Pathname:/usr/local/lib>
#   #<Pathname:/usr/local/include>
#   #<Pathname:/usr/local/sbin>
#   #<Pathname:/usr/local/src>
#   #<Pathname:/usr/local/man>

Pathname("/usr/local").each_child(false) {|f| p f }
#=> #<Pathname:share>
#   #<Pathname:bin>
#   #<Pathname:games>
#   #<Pathname:lib>
#   #<Pathname:include>
#   #<Pathname:sbin>
#   #<Pathname:src>
#   #<Pathname:man>

Note that the results never contain the entries . and .. in the directory because they are not children.

See IO#each_char.

Iterates over each character of each file in ARGF.

This method allows you to treat the files supplied on the command line as a single file consisting of the concatenation of each named file. After the last character of the first file has been returned, the first character of the second file is returned. The ARGF.filename method can be used to determine the name of the file in which the current character appears.

If no block is given, an enumerator is returned instead.

Enters exclusive section and executes the block. Leaves the exclusive section automatically when the block exits. See example under MonitorMixin.

See Mutex#synchronize

Should be implemented by a extended class.

tsort_each_child is used to iterate for child nodes of node.
