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
A StoreContext is used while validating a single certificate and holds the status involved.
Psych::Stream is a streaming YAML emitter. It will not buffer your YAML, but send it straight to an IO.
Here is an example use:
stream = Psych::Stream.new($stdout) stream.start stream.push({:foo => 'bar'}) stream.finish
YAML will be immediately emitted to $stdout with no buffering.
Psych::Stream#start will take a block and ensure that Psych::Stream#finish is called, so you can do this form:
stream = Psych::Stream.new($stdout) stream.start do |em| em.push(:foo => 'bar') end
Subclass of Zlib::Error
When zlib returns a Z_STREAM_END is return if the end of the compressed data has been reached and all uncompressed out put has been produced.
Subclass of Zlib::Error
When zlib returns a Z_STREAM_ERROR, usually if the stream state was inconsistent.
Subclass of Zlib::Error
When zlib returns a Z_VERSION_ERROR, usually if the zlib library version is incompatible with the version assumed by the caller.
Zlib::ZStream is the abstract class for the stream which handles the compressed data. The operations are defined in the subclasses: Zlib::Deflate for compression, and Zlib::Inflate for decompression.
An instance of Zlib::ZStream has one stream (struct zstream in the source) and two variable-length buffers which associated to the input (next_in) of the stream and the output (next_out) of the stream. In this document, “input buffer” means the buffer for input, and “output buffer” means the buffer for output.
Data input into an instance of Zlib::ZStream are temporally stored into the end of input buffer, and then data in input buffer are processed from the beginning of the buffer until no more output from the stream is produced (i.e. until avail_out > 0 after processing). During processing, output buffer is allocated and expanded automatically to hold all output data.
Some particular instance methods consume the data in output buffer and return them as a String.
Here is an ascii art for describing above:

"output data" "input data"
If an error occurs during processing input buffer, an exception which is a subclass of Zlib::Error is raised. At that time, both input and output buffer keep their conditions at the time when the error occurs.
Method Catalogue Many of the methods in this class are fairly low-level and unlikely to be of interest to users. In fact, users are unlikely to use this class directly; rather they will be interested in Zlib::Inflate and Zlib::Deflate.
The higher level methods are listed below.
HTTPGenericRequest is the parent of the Net::HTTPRequest class. Do not use this directly; use a subclass of Net::HTTPRequest.
Mixes in the Net::HTTPHeader module to provide easier access to HTTP headers.
HTTP request class. This class wraps together the request header and the request path. You cannot use this class directly. Instead, you should use one of its subclasses: Net::HTTP::Get, Net::HTTP::Post, Net::HTTP::Head.
