Returns true if key is a key in self, otherwise false.
Returns a new String containing informations about the map:
m = ObjectSpace::WeakKeyMap.new m[key] = value m.inspect # => "#<ObjectSpace::WeakKeyMap:0x00000001028dcba8 size=1>"
Returns HTML-unescaped string.
Returns URL-escaped string following RFC 3986.
Returns URL-unescaped string (application/x-www-form-urlencoded).
URL-decode an application/x-www-form-urlencoded string with encoding(optional).
string = CGI.unescape("%27Stop%21%27+said+Fred") # => "'Stop!' said Fred"
URL-encode a string following RFC 3986 Space characters (+“ ”+) are encoded with (+“%20”+)
url_encoded_string = CGI.escapeURIComponent("'Stop!' said Fred") # => "%27Stop%21%27%20said%20Fred"
Unescape a string that has been HTML-escaped
CGI.unescapeHTML("Usage: foo "bar" <baz>") # => "Usage: foo \"bar\" <baz>"
Creates a printable version of the digest object.
Reads at most maxlen bytes from the stream. If buf is provided it must reference a string which will receive the data.
See IO#readpartial for full details.
Pushes character c back onto the stream such that a subsequent buffered character read will return it.
Unlike IO#getc multiple bytes may be pushed back onto the stream.
Has no effect on unbuffered reads (such as sysread).
Returns true if field 'Transfer-Encoding' exists and has value 'chunked', false otherwise; see Transfer-Encoding response header:
res = Net::HTTP.get_response(hostname, '/todos/1') res['Transfer-Encoding'] # => "chunked" res.chunked? # => true
Zlib::GzipReader wrapper that unzips data.
Raises a TypeError to prevent cloning.
Removes the element of self at the given index, which must be an integer-convertible object.
When index is non-negative, deletes the element at offset index:
a = [:foo, 'bar', 2] a.delete_at(1) # => "bar" a # => [:foo, 2]
When index is negative, counts backward from the end of the array:
a = [:foo, 'bar', 2] a.delete_at(-2) # => "bar" a # => [:foo, 2]
When index is out of range, returns nil.
a = [:foo, 'bar', 2] a.delete_at(3) # => nil a.delete_at(-4) # => nil

With a block given, calls the block with each element of self; removes the element if the block returns a truthy value; returns self:
a = [:foo, 'bar', 2, 'bat'] a.delete_if {|element| element.to_s.start_with?('b') } # => [:foo, 2]
With no block given, returns a new Enumerator.
Related: see Methods for Deleting.
With a block given, calls the block with each successive element of self; stops iterating if the block returns false or nil; returns a new array containing those elements for which the block returned a truthy value:
a = [0, 1, 2, 3, 4, 5] a.take_while {|element| element < 3 } # => [0, 1, 2] a.take_while {|element| true } # => [0, 1, 2, 3, 4, 5] a.take_while {|element| false } # => []
With no block given, returns a new Enumerator.
Does not modify self.
