Results for: "to_proc"

Returns self if no arguments are given. Otherwise, converts the set to another with klass.new(self, *args, &block).

In subclasses, returns klass.new(self, *args, &block) unless overridden.

Makes a set from the enumerable object with given arguments. Needs to +require “set”+ to use this method.

Dump Ruby object to a JSON string.

Convert a reference into an object using the current server.

This raises a DRbServerNotFound error if there is no current server. See current_server.

Get a reference id for an object using the current server.

This raises a DRbServerNotFound error if there is no current server. See current_server.

Get a reference id for an object using the current server.

This raises a DRbServerNotFound error if there is no current server. See current_server.

Convert a reference into an object using the current server.

This raises a DRbServerNotFound error if there is no current server. See current_server.

Module managing the underlying network protocol(s) used by drb.

By default, drb uses the DRbTCPSocket protocol. Other protocols can be defined. A protocol must define the following class methods:

[open(uri, config)] Open a client connection to the server at +uri+,
                    using configuration +config+.  Return a protocol
                    instance for this connection.
[open_server(uri, config)] Open a server listening at +uri+,
                           using configuration +config+.  Return a
                           protocol instance for this listener.
[uri_option(uri, config)] Take a URI, possibly containing an option
                          component (e.g. a trailing '?param=val'),
                          and return a [uri, option] tuple.

All of these methods should raise a DRbBadScheme error if the URI does not identify the protocol they support (e.g. “druby:” for the standard Ruby protocol). This is how the DRbProtocol module, given a URI, determines which protocol implementation serves that protocol.

The protocol instance returned by open_server must have the following methods:

accept

Accept a new connection to the server. Returns a protocol instance capable of communicating with the client.

close

Close the server connection.

uri

Get the URI for this server.

The protocol instance returned by open must have the following methods:

send_request (ref, msg_id, arg, b)

Send a request to ref with the given message id and arguments. This is most easily implemented by calling DRbMessage.send_request, providing a stream that sits on top of the current protocol.

recv_reply

Receive a reply from the server and return it as a [success-boolean, reply-value] pair. This is most easily implemented by calling DRb.recv_reply, providing a stream that sits on top of the current protocol.

alive?

Is this connection still alive?

close

Close this connection.

The protocol instance returned by open_server().accept() must have the following methods:

recv_request

Receive a request from the client and return a [object, message, args, block] tuple. This is most easily implemented by calling DRbMessage.recv_request, providing a stream that sits on top of the current protocol.

send_reply(succ, result)

Send a reply to the client. This is most easily implemented by calling DRbMessage.send_reply, providing a stream that sits on top of the current protocol.

close

Close this connection.

A new protocol is registered with the DRbProtocol module using the add_protocol method.

For examples of other protocols, see DRbUNIXSocket in drb/unix.rb, and HTTP0 in sample/http0.rb and sample/http0serv.rb in the full drb distribution.

Protocol error.

call-seq

WIN32OLE_METHOD#name

Returns the name of the method.

tobj = WIN32OLE_TYPE.new('Microsoft Excel 9.0 Object Library', 'Workbook')
method = WIN32OLE_METHOD.new(tobj, 'SaveAs')
puts method.name # => SaveAs

Returns name.

tobj = WIN32OLE_TYPE.new('Microsoft Excel 9.0 Object Library', 'Workbook')
method = WIN32OLE_METHOD.new(tobj, 'SaveAs')
param1 = method.params[0]
puts param1.name # => Filename

Returns Ruby Hash object which represents VT_RECORD variable. The keys of Hash object are member names of VT_RECORD OLE variable and the values of Hash object are values of VT_RECORD OLE variable.

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, the result of WIN32OLE_RECORD#to_h is the following:

require 'win32ole'
obj = WIN32OLE.new('ComServer.ComClass')
book = obj.getBook
book.to_h # => {"title"=>"The Ruby Book", "cost"=>20}
