Returns the resulting hash value and resets the digest to the initial state.
If none is given, returns the resulting hash value of the digest in a hex-encoded form, keeping the digest’s state.
If a string is given, returns the hash value for the given string in a hex-encoded form, resetting the digest to the initial state before and after the process.
Returns the resulting hash value in a hex-encoded form and resets the digest to the initial state.
If none is given, returns the resulting hash value of the digest in a base64 encoded form, keeping the digest’s state.
If a string
is given, returns the hash value for the given string
in a base64 encoded form, resetting the digest to the initial state before and after the process.
In either case, the return value is properly padded with ‘=’ and contains no line feeds.
Returns the resulting hash value and resets the digest to the initial state.
Creates a class to wrap the C struct described by signature
.
MyStruct = struct ['int i', 'char c']
Creates a class to wrap the C union described by signature
.
MyUnion = union ['int i', 'char c']
Decodes a BER- or DER-encoded value and creates an ASN1Data
instance. der may be a String
or any object that features a .to_der
method transforming it into a BER-/DER-encoded String+
der = File.binread('asn1data') asn1 = OpenSSL::ASN1.decode(der)
Return true
if the PRNG has been seeded with enough data, false
otherwise.

Generate a Table Caption element as a string.
align
can be a string, giving the alignment of the caption (one of top, bottom, left, or right). It can be a hash of all the attributes of the element. Or it can be omitted.
The body of the element is provided by the passed-in no-argument block.
caption("left") { "Capital Cities" } # => <CAPTION ALIGN=\"left\">Capital Cities</CAPTION>
Adds a separated list. The list is separated by comma with breakable space, by default.
seplist
iterates the list
using iter_method
. It yields each object to the block given for seplist
. The procedure separator_proc
is called between each yields.
If the iteration is zero times, separator_proc
is not called at all.
If separator_proc
is nil or not given, +lambda { comma_breakable
}+ is used. If iter_method
is not given, :each is used.
For example, following 3 code fragments has similar effect.
q.seplist([1,2,3]) {|v| xxx v } q.seplist([1,2,3], lambda { q.comma_breakable }, :each) {|v| xxx v } xxx 1 q.comma_breakable xxx 2 q.comma_breakable xxx 3
The host to connect to either from the RUBYGEMS_HOST environment variable or from the user’s configuration
(see Gem::Resolver::Molinillo::ResolutionState#conflicts)
Replaces the content of self
with the content of other_array
; returns self
:
a = [:foo, 'bar', 2] a.replace(['foo', :bar, 3]) # => ["foo", :bar, 3]
Returns the singleton class of obj. This method creates a new singleton class if obj does not have one.
If obj is nil
, true
, or false
, it returns NilClass
, TrueClass
, or FalseClass
, respectively. If obj is an Integer
, a Float
or a Symbol
, it raises a TypeError
.
Object.new.singleton_class #=> #<Class:#<Object:0xb7ce1e24>> String.singleton_class #=> #<Class:String> nil.singleton_class #=> NilClass
Returns an array of the names of singleton methods for obj. If the optional all parameter is true, the list will include methods in modules included in obj. Only public and protected singleton methods are returned.
module Other def three() end end class Single def Single.four() end end a = Single.new def a.one() end class << a include Other def two() end end Single.singleton_methods #=> [:four] a.singleton_methods(false) #=> [:two, :one] a.singleton_methods #=> [:two, :one, :three]
Similar to method, searches singleton method only.
class Demo def initialize(n) @iv = n end def hello() "Hello, @iv = #{@iv}" end end k = Demo.new(99) def k.hi "Hi, @iv = #{@iv}" end m = k.singleton_method(:hi) m.call #=> "Hi, @iv = 99" m = k.singleton_method(:hello) #=> NameError
Returns the factorization of self
.
See Prime#prime_division
for more details.
Returns a hash, that will be turned into a JSON
object and represent this object.
