Returns the current object method calls are being delegated to.

Changes the delegate object to obj.

It’s important to note that this does not cause SimpleDelegator’s methods to change. Because of this, you probably only want to change delegation to objects of the same type as the original delegate.

Here’s an example of changing the delegation object.

names = SimpleDelegator.new(%w{James Edward Gray II})
puts names[1]    # => Edward
names.__setobj__(%w{Gavin Sinclair})
puts names[1]    # => Sinclair

Wrapper method for getopts.rb.

params = ARGV.getopts("ab:", "foo", "bar:", "zot:Z;zot option")

# params["b"] = "1"    # -b1
# params["foo"] = "1"  # --foo
# params["bar"] = "x"  # --bar x
# params["zot"] = "z"  # --zot Z

Stops execution of the current thread, putting it into a “sleep” state, and schedules execution of another thread.

a.run
a.join
#=> "abc"

Returns true if thr is dead or sleeping.

a = Thread.new { Thread.stop }
b = Thread.current
a.stop?   #=> true
b.stop?   #=> false

Registers filename to be loaded (using Kernel::require) the first time that module (which may be a String or a symbol) is accessed.

autoload(:MyModule, "/usr/local/lib/modules/my_module.rb")

Returns filename to be loaded if name is registered as autoload.

autoload(:B, "b")
autoload?(:B)            #=> "b"

Returns true if yield would execute a block in the current context. The iterator? form is mildly deprecated.

end
try                  #=> "no block"
try { "hello" }      #=> "hello"
try do "hello" end   #=> "hello"
