WIN32OLE_EVENT objects controls OLE event.

WIN32OLE_PARAM objects represent param information of the OLE method.

WIN32OLE_RECORD objects represents VT_RECORD OLE variant. Win32OLE returns WIN32OLE_RECORD object if the result value of invoking OLE methods.

If COM server in VB.NET ComServer project is the following:

Imports System.Runtime.InteropServices
Public Class ComClass
    Public Structure Book
        <MarshalAs(UnmanagedType.BStr)> _
        Public title As String
        Public cost As Integer
    End Structure
    Public Function getBook() As Book
        Dim book As New Book
        book.title = "The Ruby Book"
        book.cost = 20
        Return book
    End Function
End Class

then, you can retrieve getBook return value from the following Ruby script:

require 'win32ole'
obj = WIN32OLE.new('ComServer.ComClass')
book = obj.getBook
book.class # => WIN32OLE_RECORD
book.title # => "The Ruby Book"
book.cost  # => 20

WIN32OLE_TYPE objects represent OLE type libarary information.

WIN32OLE_TYPELIB objects represent OLE tyblib information.

WIN32OLE_VARIANT objects represents OLE variant.

Win32OLE converts Ruby object into OLE variant automatically when invoking OLE methods. If OLE method requires the argument which is different from the variant by automatic conversion of Win32OLE, you can convert the specfied variant type by using WIN32OLE_VARIANT class.

param = WIN32OLE_VARIANT.new(10, WIN32OLE::VARIANT::VT_R4)
oleobj.method(param)

WIN32OLE_VARIANT does not support VT_RECORD variant. Use WIN32OLE_RECORD class instead of WIN32OLE_VARIANT if the VT_RECORD variant is needed.

The parent class for all constructed encodings. The value attribute of a Constructive is always an Array. Attributes are the same as for ASN1Data, with the addition of tagging.

SET and SEQUENCE

Most constructed encodings come in the form of a SET or a SEQUENCE. These encodings are represented by one of the two sub-classes of Constructive:

• OpenSSL::ASN1::Set

• OpenSSL::ASN1::Sequence

Please note that tagged sequences and sets are still parsed as instances of ASN1Data. Find further details on tagged values there.

Example - constructing a SEQUENCE

int = OpenSSL::ASN1::Integer.new(1)
str = OpenSSL::ASN1::PrintableString.new('abc')
sequence = OpenSSL::ASN1::Sequence.new( [ int, str ] )

Example - constructing a SET

int = OpenSSL::ASN1::Integer.new(1)
str = OpenSSL::ASN1::PrintableString.new('abc')
set = OpenSSL::ASN1::Set.new( [ int, str ] )

Infinite length primitive values

The only case where Constructive is used directly is for infinite length encodings of primitive values. These encodings are always constructed, with the contents of the value Array being either UNIVERSAL non-infinite length partial encodings of the actual value or again constructive encodings with infinite length (i.e. infinite length primitive encodings may be constructed recursively with another infinite length value within an already infinite length value). Each partial encoding must be of the same UNIVERSAL type as the overall encoding. The value of the overall encoding consists of the concatenation of each partial encoding taken in sequence. The value array of the outer infinite length value must end with a OpenSSL::ASN1::EndOfContent instance.

Please note that it is not possible to encode Constructive without the infinite_length attribute being set to true, use OpenSSL::ASN1::Sequence or OpenSSL::ASN1::Set in these cases instead.

Example - Infinite length OCTET STRING

partial1 = OpenSSL::ASN1::OctetString.new("\x01")
partial2 = OpenSSL::ASN1::OctetString.new("\x02")
inf_octets = OpenSSL::ASN1::Constructive.new( [ partial1,
                                                partial2,
                                                OpenSSL::ASN1::EndOfContent.new ],
                                              OpenSSL::ASN1::OCTET_STRING,
                                              nil,
                                              :UNIVERSAL )
# The real value of inf_octets is "\x01\x02", i.e. the concatenation
# of partial1 and partial2
inf_octets.infinite_length = true
der = inf_octets.to_der
asn1 = OpenSSL::ASN1.decode(der)
puts asn1.infinite_length # => true

Switch that can omit argument.

Represents a specification retrieved via the rubygems.org API.

This is used to avoid loading the full Specification object when all we need is the name, version, and dependencies.

A GitSpecification represents a gem that is sourced from a git repository and is being loaded through a gem dependencies file through the git: option.

Represents a possible Specification object returned from IndexSet. Used to delay needed to download full Specification objects when only the name and version are needed.

A LocalSpecification comes from a .gem file on the local filesystem.

The LockSpecification comes from a lockfile (Gem::RequestSet::Lockfile).

A LockSpecification’s dependency information is pre-filled from the lockfile.

The Resolver::SpecSpecification contains common functionality for Resolver specifications that are backed by a Gem::Specification.

A Resolver::Specification contains a subset of the information contained in a Gem::Specification. Only the information necessary for dependency resolution in the resolver is included.

A VendorSpecification represents a gem that has been unpacked into a project and is being loaded through a gem dependencies file through the path: option.

Gem::Security default exception type

An object representation of a stack frame, initialized by Kernel#caller_locations.

For example:

# caller_locations.rb
def a(skip)
  caller_locations(skip)
end
def b(skip)
  a(skip)
end
def c(skip)
  b(skip)
end

c(0..2).map do |call|
  puts call.to_s
end

Running ruby caller_locations.rb will produce:

caller_locations.rb:2:in `a'
caller_locations.rb:5:in `b'
caller_locations.rb:8:in `c'

Here’s another example with a slightly different result:

# foo.rb
class Foo
  attr_accessor :locations
  def initialize(skip)
    @locations = caller_locations(skip)
  end
end

Foo.new(0..2).locations.map do |call|
  puts call.to_s
end

Now run ruby foo.rb and you should see:

init.rb:4:in `initialize'
init.rb:8:in `new'
init.rb:8:in `<main>'
