Extracts the certificate chain from the spec and calls verify to ensure the signatures and certificate chain is valid according to the policy..
Raises a MissingTagError or NotExpectedTagError if the element is not properly formatted.
Raises NotAvailableValueError if element content is nil
Get all [gem, version] from the command line.
An argument in the form gem:ver is pull apart into the gen name and version, respectively.
Finds a spec and the source_uri it came from for gem gem_name and version. Returns an Array of specs and sources required for installation of the gem.
Returns the element at index. A negative index counts from the end of self. Returns nil if the index is out of range. See also Array#[].
a = [ "a", "b", "c", "d", "e" ] a.at(0) #=> "a" a.at(-1) #=> "e"
Appends the elements of other_arys to self.
[ "a", "b" ].concat( ["c", "d"]) #=> [ "a", "b", "c", "d" ] [ "a" ].concat( ["b"], ["c", "d"]) #=> [ "a", "b", "c", "d" ] [ "a" ].concat #=> [ "a" ] a = [ 1, 2, 3 ] a.concat( [ 4, 5 ]) a #=> [ 1, 2, 3, 4, 5 ] a = [ 1, 2 ] a.concat(a, a) #=> [1, 2, 1, 2, 1, 2]
See also Array#+.
Returns the number of elements in self. May be zero.
[ 1, 2, 3, 4, 5 ].length #=> 5 [].length #=> 0
Returns a new array by rotating self so that the element at count is the first element of the new array.
If count is negative then it rotates in the opposite direction, starting from the end of self where -1 is the last element.
a = [ "a", "b", "c", "d" ] a.rotate #=> ["b", "c", "d", "a"] a #=> ["a", "b", "c", "d"] a.rotate(2) #=> ["c", "d", "a", "b"] a.rotate(-3) #=> ["b", "c", "d", "a"]
Rotates self in place so that the element at count comes first, and returns self.
If count is negative then it rotates in the opposite direction, starting from the end of the array where -1 is the last element.
a = [ "a", "b", "c", "d" ] a.rotate! #=> ["b", "c", "d", "a"] a #=> ["b", "c", "d", "a"] a.rotate!(2) #=> ["d", "a", "b", "c"] a.rotate!(-3) #=> ["a", "b", "c", "d"]
Returns a copy of self with all nil elements removed.
[ "a", nil, "b", nil, "c", nil ].compact #=> [ "a", "b", "c" ]
Removes nil elements from the array.
Returns nil if no changes were made, otherwise returns the array.
[ "a", nil, "b", nil, "c" ].compact! #=> [ "a", "b", "c" ] [ "a", "b", "c" ].compact! #=> nil
