Creates a new CGI interface.
The first argument in args is a configuration hash which would update WEBrick::Config::HTTP.
Any remaining arguments are stored in the @options instance variable for use by a subclass.
Creates a new cookie with the given name and value
Proxy server configurations. The proxy server handles the following configuration items in addition to those supported by HTTPServer:
Called with a request and response to authorize a request
Appended to the via header
The proxy server’s URI
Called with a request and response and allows modification of the response
Sets the proxy timeouts to 30 seconds for open and 60 seconds for read operations
Creates a new HTTP request. WEBrick::Config::HTTP is the default configuration.
Creates a new HTTP response object. WEBrick::Config::HTTP is the default configuration.
Creates a new HTTP server according to config
An HTTP server uses the following attributes:
An array of access logs. See WEBrick::AccessLog
Local address for the server to bind to
Root path to serve files from
Options for the default HTTPServlet::FileHandler
The HTTP version of this server
Port to listen on
Called with a request and response before each request is serviced.
Maximum time to wait between requests
Array of alternate names for this server for virtual hosting
Name for this server for virtual hosting
Creates a new HTTPVersion from version.
Initializes a new logger for log_file that outputs messages at level or higher. log_file can be a filename, an IO-like object that responds to << or nil which outputs to $stderr.
If no level is given INFO is chosen by default
Creates a new generic server from config. The default configuration comes from default.
Creates a new YAML::Store object, which will store data in file_name. If the file does not already exist, it will be created.
YAML::Store objects are always reentrant. But if thread_safe is set to true, then it will become thread-safe at the cost of a minor performance hit.
Options passed in through yaml_opts will be used when converting the store to YAML via Hash#to_yaml().
Creates a new Mutex
Creates a new queue instance.
Creates a fixed-length queue with a maximum size of max.
Creates a new condition variable instance.
possible options elements:

:undef => :replace # replace undefined conversion
:replace => string # replacement string ("?" or "\uFFFD" if not specified)

Encoding::Converter::UNIVERSAL_NEWLINE_DECORATOR
Encoding::Converter::CRLF_NEWLINE_DECORATOR
Encoding::Converter::CR_NEWLINE_DECORATOR
Encoding::Converter::XML_TEXT_DECORATOR
Encoding::Converter::XML_ATTR_CONTENT_DECORATOR
Encoding::Converter::XML_ATTR_QUOTE_DECORATOR
Encoding::Converter.new creates an instance of Encoding::Converter.
Source_encoding and destination_encoding should be a string or Encoding object.
opt should be nil, a hash or an integer.
convpath should be an array. convpath may contain
two-element arrays which contain encodings or encoding names, or
strings representing decorator names.
Encoding::Converter.new optionally takes an option. The option should be a hash or an integer. The option hash can contain :invalid => nil, etc. The option integer should be logical-or of constants such as Encoding::Converter::INVALID_REPLACE, etc.
Raise error on invalid byte sequence. This is a default behavior.
Replace invalid byte sequence by replacement string.
Raise an error if a character in source_encoding is not defined in destination_encoding. This is a default behavior.
Replace undefined character in destination_encoding with replacement string.
Specify the replacement string. If not specified, “uFFFD” is used for Unicode encodings and “?” for others.
Convert CRLF and CR to LF.
Convert LF to CRLF.
Convert LF to CR.
Escape as XML CharData. This form can be used as an HTML 4.0 PCDATA.
‘&’ -> ‘&’
‘<’ -> ‘<’
‘>’ -> ‘>’
undefined characters in destination_encoding -> hexadecimal CharRef such as &#xHH;
Escape as XML AttValue. The converted result is quoted as “…”. This form can be used as an HTML 4.0 attribute value.
‘&’ -> ‘&’
‘<’ -> ‘<’
‘>’ -> ‘>’
‘“’ -> ‘"’
undefined characters in destination_encoding -> hexadecimal CharRef such as &#xHH;
Examples:
# UTF-16BE to UTF-8 ec = Encoding::Converter.new("UTF-16BE", "UTF-8") # Usually, decorators such as newline conversion are inserted last. ec = Encoding::Converter.new("UTF-16BE", "UTF-8", :universal_newline => true) p ec.convpath #=> [[#<Encoding:UTF-16BE>, #<Encoding:UTF-8>], # "universal_newline"] # But, if the last encoding is ASCII incompatible, # decorators are inserted before the last conversion. ec = Encoding::Converter.new("UTF-8", "UTF-16BE", :crlf_newline => true) p ec.convpath #=> ["crlf_newline", # [#<Encoding:UTF-8>, #<Encoding:UTF-16BE>]] # Conversion path can be specified directly. ec = Encoding::Converter.new(["universal_newline", ["EUC-JP", "UTF-8"], ["UTF-8", "UTF-16BE"]]) p ec.convpath #=> ["universal_newline", # [#<Encoding:EUC-JP>, #<Encoding:UTF-8>], # [#<Encoding:UTF-8>, #<Encoding:UTF-16BE>]]
Returns a new, initialized copy of the digest object. Equivalent to digest_obj.clone().reset().
Creates an instance of OpenSSL’s buffering IO module.
newton.rb
Solves the nonlinear algebraic equation system f = 0 by Newton’s method. This program is not dependent on BigDecimal.
To call:
n = nlsolve(f,x)
where n is the number of iterations required,
x is the initial value vector
f is an Object which is used to compute the values of the equations to be solved.
It must provide the following methods:
returns the values of all functions at x
returns 0.0
returns 1.0
returns 2.0
returns 10.0
returns the convergence criterion (epsilon value) used to determine whether two values are considered equal. If |a-b| < epsilon, the two values are considered equal.
On exit, x is the solution vector.
URI::Parser.new([opts])
The constructor accepts a hash as options for parser. Keys of options are pattern names of URI components and values of options are pattern strings. The constructor generates set of regexps for parsing URIs.
You can use the following keys:
* :ESCAPED (URI::PATTERN::ESCAPED in default) * :UNRESERVED (URI::PATTERN::UNRESERVED in default) * :DOMLABEL (URI::PATTERN::DOMLABEL in default) * :TOPLABEL (URI::PATTERN::TOPLABEL in default) * :HOSTNAME (URI::PATTERN::HOSTNAME in default)
p = URI::Parser.new(:ESCAPED => "(?:%[a-fA-F0-9]{2}|%u[a-fA-F0-9]{4})") u = p.parse("http://example.jp/%uABCD") #=> #<URI::HTTP:0xb78cf4f8 URL:http://example.jp/%uABCD> URI.parse(u.to_s) #=> raises URI::InvalidURIError s = "http://example.com/ABCD" u1 = p.parse(s) #=> #<URI::HTTP:0xb78c3220 URL:http://example.com/ABCD> u2 = URI.parse(s) #=> #<URI::HTTP:0xb78b6d54 URL:http://example.com/ABCD> u1 == u2 #=> true u1.eql?(u2) #=> false
Creates a DRb::DRbObject given the reference information to the remote host uri and object ref.
