Takes a token and gets the next token in the Negotiate authentication chain. Token can be Base64 encoded or not. The token can include the “Negotiate” header and it will be stripped. Does not indicate if SEC_I_CONTINUE or SEC_E_OK was returned. Token returned is Base64 encoded w/ all new lines removed.
Extracts the certificate chain from the spec and calls verify to ensure the signatures and certificate chain is valid according to the policy..
Returns the element at Integer offset index; does not modify self.
a = [:foo, 'bar', 2] a.at(0) # => :foo a.at(2) # => 2
Adds to array all elements from each Array in other_arrays; returns self:
a = [0, 1] a.concat([2, 3], [4, 5]) # => [0, 1, 2, 3, 4, 5]
Returns the count of elements in self.
Returns a new Array formed from self with elements rotated from one end to the other.
When no argument given, returns a new Array that is like self, except that the first element has been rotated to the last position:
a = [:foo, 'bar', 2, 'bar'] a1 = a.rotate a1 # => ["bar", 2, "bar", :foo]
When given a non-negative Integer count, returns a new Array with count elements rotated from the beginning to the end:
a = [:foo, 'bar', 2] a1 = a.rotate(2) a1 # => [2, :foo, "bar"]
If count is large, uses count % array.size as the count:
a = [:foo, 'bar', 2] a1 = a.rotate(20) a1 # => [2, :foo, "bar"]
If count is zero, returns a copy of self, unmodified:
a = [:foo, 'bar', 2] a1 = a.rotate(0) a1 # => [:foo, "bar", 2]
When given a negative Integer count, rotates in the opposite direction, from end to beginning:
a = [:foo, 'bar', 2] a1 = a.rotate(-2) a1 # => ["bar", 2, :foo]
If count is small (far from zero), uses count % array.size as the count:
a = [:foo, 'bar', 2] a1 = a.rotate(-5) a1 # => ["bar", 2, :foo]
Rotates self in place by moving elements from one end to the other; returns self.
When no argument given, rotates the first element to the last position:
a = [:foo, 'bar', 2, 'bar'] a.rotate! # => ["bar", 2, "bar", :foo]
When given a non-negative Integer count, rotates count elements from the beginning to the end:
a = [:foo, 'bar', 2] a.rotate!(2) a # => [2, :foo, "bar"]
If count is large, uses count % array.size as the count:
a = [:foo, 'bar', 2] a.rotate!(20) a # => [2, :foo, "bar"]
If count is zero, returns self unmodified:
a = [:foo, 'bar', 2] a.rotate!(0) a # => [:foo, "bar", 2]
When given a negative Integer count, rotates in the opposite direction, from end to beginning:
a = [:foo, 'bar', 2] a.rotate!(-2) a # => ["bar", 2, :foo]
If count is small (far from zero), uses count % array.size as the count:
a = [:foo, 'bar', 2] a.rotate!(-5) a # => ["bar", 2, :foo]
Returns a new Array containing all non-nil elements from self:
a = [nil, 0, nil, 1, nil, 2, nil] a.compact # => [0, 1, 2]
Removes all nil elements from self.
Returns self if any elements removed, otherwise nil.
Returns a new Array that is a recursive flattening of self:
Each non-Array element is unchanged.
Each Array is replaced by its individual elements.
With non-negative Integer argument level, flattens recursively through level levels:
a = [ 0, [ 1, [2, 3], 4 ], 5 ] a.flatten(0) # => [0, [1, [2, 3], 4], 5] a = [ 0, [ 1, [2, 3], 4 ], 5 ] a.flatten(1) # => [0, 1, [2, 3], 4, 5] a = [ 0, [ 1, [2, 3], 4 ], 5 ] a.flatten(2) # => [0, 1, 2, 3, 4, 5] a = [ 0, [ 1, [2, 3], 4 ], 5 ] a.flatten(3) # => [0, 1, 2, 3, 4, 5]
With no argument, a nil argument, or with negative argument level, flattens all levels:
a = [ 0, [ 1, [2, 3], 4 ], 5 ] a.flatten # => [0, 1, 2, 3, 4, 5] [0, 1, 2].flatten # => [0, 1, 2] a = [ 0, [ 1, [2, 3], 4 ], 5 ] a.flatten(-1) # => [0, 1, 2, 3, 4, 5] a = [ 0, [ 1, [2, 3], 4 ], 5 ] a.flatten(-2) # => [0, 1, 2, 3, 4, 5] [0, 1, 2].flatten(-1) # => [0, 1, 2]
Replaces each nested Array in self with the elements from that Array; returns self if any changes, nil otherwise.
With non-negative Integer argument level, flattens recursively through level levels:
a = [ 0, [ 1, [2, 3], 4 ], 5 ] a.flatten!(1) # => [0, 1, [2, 3], 4, 5] a = [ 0, [ 1, [2, 3], 4 ], 5 ] a.flatten!(2) # => [0, 1, 2, 3, 4, 5] a = [ 0, [ 1, [2, 3], 4 ], 5 ] a.flatten!(3) # => [0, 1, 2, 3, 4, 5] [0, 1, 2].flatten!(1) # => nil
With no argument, a nil argument, or with negative argument level, flattens all levels:
a = [ 0, [ 1, [2, 3], 4 ], 5 ] a.flatten! # => [0, 1, 2, 3, 4, 5] [0, 1, 2].flatten! # => nil a = [ 0, [ 1, [2, 3], 4 ], 5 ] a.flatten!(-1) # => [0, 1, 2, 3, 4, 5] a = [ 0, [ 1, [2, 3], 4 ], 5 ] a.flatten!(-2) # => [0, 1, 2, 3, 4, 5] [0, 1, 2].flatten!(-1) # => nil
When invoked with a block, yield all permutations of elements of self; returns self. The order of permutations is indeterminate.
When a block and an in-range positive Integer argument n (0 < n <= self.size) are given, calls the block with all n-tuple permutations of self.
Example:
a = [0, 1, 2] a.permutation(2) {|permutation| p permutation }
Output:
[0, 1] [0, 2] [1, 0] [1, 2] [2, 0] [2, 1]
Another example:
a = [0, 1, 2] a.permutation(3) {|permutation| p permutation }
Output:
[0, 1, 2] [0, 2, 1] [1, 0, 2] [1, 2, 0] [2, 0, 1] [2, 1, 0]
When n is zero, calls the block once with a new empty Array:
a = [0, 1, 2] a.permutation(0) {|permutation| p permutation }
Output:
[]
When n is out of range (negative or larger than self.size), does not call the block:
a = [0, 1, 2] a.permutation(-1) {|permutation| fail 'Cannot happen' } a.permutation(4) {|permutation| fail 'Cannot happen' }
When a block given but no argument, behaves the same as a.permutation(a.size):
a = [0, 1, 2] a.permutation {|permutation| p permutation }
Output:
[0, 1, 2] [0, 2, 1] [1, 0, 2] [1, 2, 0] [2, 0, 1] [2, 1, 0]
Returns a new Enumerator if no block given:
a = [0, 1, 2] a.permutation # => #<Enumerator: [0, 1, 2]:permutation> a.permutation(2) # => #<Enumerator: [0, 1, 2]:permutation(2)>
Returns random elements from self.
When no arguments are given, returns a random element from self:
a = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10] a.sample # => 3 a.sample # => 8
If self is empty, returns nil.
When argument n is given, returns a new Array containing n random elements from self:
a.sample(3) # => [8, 9, 2] a.sample(6) # => [9, 6, 10, 3, 1, 4]
Returns no more than a.size elements (because no new duplicates are introduced):
a.sample(a.size * 2) # => [6, 4, 1, 8, 5, 9, 10, 2, 3, 7]
But self may contain duplicates:
a = [1, 1, 1, 2, 2, 3] a.sample(a.size * 2) # => [1, 1, 3, 2, 1, 2]
The argument n must be a non-negative numeric value. The order of the result array is unrelated to the order of self. Returns a new empty Array if self is empty.
The optional random argument will be used as the random number generator:
a = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10] a.sample(random: Random.new(1)) #=> 6 a.sample(4, random: Random.new(1)) #=> [6, 10, 9, 2]
Formats each element in self into a binary string; returns that string. See Packed Data.
Returns a Hash containing implementation-dependent counters inside the VM.
This hash includes information about method/constant caches:
{
:constant_cache_invalidations=>2,
:constant_cache_misses=>14,
:global_cvar_state=>27
}
If USE_DEBUG_COUNTER is enabled, debug counters will be included.
The contents of the hash are implementation specific and may be changed in the future.
This method is only expected to work on C Ruby.
Returns self truncated (toward zero) to a precision of ndigits decimal digits.
When ndigits is negative, the returned value has at least ndigits.abs trailing zeros:
555.truncate(-1) # => 550 555.truncate(-2) # => 500 -555.truncate(-2) # => -500
Returns self when ndigits is zero or positive.
555.truncate # => 555 555.truncate(50) # => 555
Related: Integer#round.
Calls the given block self times with each integer in (0..self-1):
a = [] 5.times {|i| a.push(i) } # => 5 a # => [0, 1, 2, 3, 4]
With no block given, returns an Enumerator.
Returns the imaginary value for self:
Complex(7).imaginary #=> 0 Complex(9, -4).imaginary #=> -4
If self was created with polar coordinates, the returned value is computed, and may be inexact:
Complex.polar(1, Math::PI/4).imag # => 0.7071067811865476 # Square root of 2.
