creates a new Socket connected to the address of local_addrinfo.

If local_addrinfo is nil, the address of the socket is not bound.

The timeout specify the seconds for timeout. Errno::ETIMEDOUT is raised when timeout occur.

If a block is given the created socket is yielded for each address.

returns a string which shows the sockaddr in addrinfo with human-readable form.

Addrinfo.tcp("localhost", 80).inspect_sockaddr     #=> "127.0.0.1:80"
Addrinfo.tcp("ip6-localhost", 80).inspect_sockaddr #=> "[::1]:80"
Addrinfo.unix("/tmp/sock").inspect_sockaddr        #=> "/tmp/sock"

Returns true for IPv4 private address (10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16). It returns false otherwise.

Returns true for IPv4 multicast address (224.0.0.0/4). It returns false otherwise.

Returns true for IPv6 multicast address (ff00::/8). It returns false otherwise.

Returns true for IPv6 link local address (ff80::/10). It returns false otherwise.

Closes the write end of a StringIO. Will raise an IOError if the receiver is not writeable.

Returns true if the stream is not writable, false otherwise.

Duplicates a StringScanner object.

This method is defined for backward compatibility.

Returns the post-match

s = StringScanner.new('test string')
s.scan(/\w+/)           # -> "test"
s.scan(/\s+/)           # -> " "
s.pre_match             # -> "test"
s.post_match            # -> "string"

s.rest_size is equivalent to s.rest.size.

Defines the constants of OLE Automation server as mod’s constants. The first argument is WIN32OLE object or type library name. If 2nd argument is omitted, the default is WIN32OLE. The first letter of Ruby’s constant variable name is upper case, so constant variable name of WIN32OLE object is capitalized. For example, the ‘xlTop’ constant of Excel is changed to ‘XlTop’ in WIN32OLE. If the first letter of constant variable is not [A-Z], then the constant is defined as CONSTANTS hash element.

module EXCEL_CONST
end
excel = WIN32OLE.new('Excel.Application')
WIN32OLE.const_load(excel, EXCEL_CONST)
puts EXCEL_CONST::XlTop # => -4160
puts EXCEL_CONST::CONSTANTS['_xlDialogChartSourceData'] # => 541

WIN32OLE.const_load(excel)
puts WIN32OLE::XlTop # => -4160

module MSO
end
WIN32OLE.const_load('Microsoft Office 9.0 Object Library', MSO)
puts MSO::MsoLineSingle # => 1

Returns event interface name if the method is event.

tobj = WIN32OLE_TYPE.new('Microsoft Excel 9.0 Object Library', 'Workbook')
method = WIN32OLE_METHOD.new(tobj, 'SheetActivate')
puts method.event_interface # =>  WorkbookEvents

Returns minor version.

tobj = WIN32OLE_TYPE.new('Microsoft Word 10.0 Object Library', 'Documents')
puts tobj.minor_version # => 2

Returns the type library minor version.

tlib = WIN32OLE_TYPELIB.new('Microsoft Excel 9.0 Object Library')
puts tlib.minor_version # -> 3

If obj is a Hash object, returns obj.

Otherwise if obj responds to :to_hash, calls obj.to_hash and returns the result.

Returns nil if obj does not respond to :to_hash

Raises an exception unless obj.to_hash returns a Hash object.

Replaces the entire contents of self with the contents of other_hash; returns self:

h = {foo: 0, bar: 1, baz: 2}
h.replace({bat: 3, bam: 4}) # => {:bat=>3, :bam=>4}

Returns a new Hash object; each entry has:

• A key provided by the block.

• The value from self.

An optional hash argument can be provided to map keys to new keys. Any key not given will be mapped using the provided block, or remain the same if no block is given.

Transform keys:

h = {foo: 0, bar: 1, baz: 2}
h1 = h.transform_keys {|key| key.to_s }
h1 # => {"foo"=>0, "bar"=>1, "baz"=>2}

h.transform_keys(foo: :bar, bar: :foo)
#=> {bar: 0, foo: 1, baz: 2}

h.transform_keys(foo: :hello, &:to_s)
#=> {:hello=>0, "bar"=>1, "baz"=>2}

Overwrites values for duplicate keys:

h = {foo: 0, bar: 1, baz: 2}
h1 = h.transform_keys {|key| :bat }
h1 # => {:bat=>2}

Returns a new Enumerator if no block given:

h = {foo: 0, bar: 1, baz: 2}
e = h.transform_keys # => #<Enumerator: {:foo=>0, :bar=>1, :baz=>2}:transform_keys>
h1 = e.each { |key| key.to_s }
h1 # => {"foo"=>0, "bar"=>1, "baz"=>2}

Same as Hash#transform_keys but modifies the receiver in place instead of returning a new hash.

Returns a new Hash object; each entry has:

• A key from self.

• A value provided by the block.

Transform values:

h = {foo: 0, bar: 1, baz: 2}
h1 = h.transform_values {|value| value * 100}
h1 # => {:foo=>0, :bar=>100, :baz=>200}

Returns a new Enumerator if no block given:

h = {foo: 0, bar: 1, baz: 2}
e = h.transform_values # => #<Enumerator: {:foo=>0, :bar=>1, :baz=>2}:transform_values>
h1 = e.each { |value| value * 100}
h1 # => {:foo=>0, :bar=>100, :baz=>200}
