Results for: "Array.new"

Creates a ThreadsWait object, specifying the threads to wait on. Non-blocking.

Creates a weak reference to orig

Raises an ArgumentError if the given orig is immutable, such as Symbol, Integer, or Float.

Creates a new thread executing the given block.

Any args given to ::new will be passed to the block:

arr = []
a, b, c = 1, 2, 3
Thread.new(a,b,c) { |d,e,f| arr << d << e << f }.join
arr #=> [1, 2, 3]

A ThreadError exception is raised if ::new is called without a block.

If you’re going to subclass Thread, be sure to call super in your initialize method, otherwise a ThreadError will be raised.

Creates a new Proc object, bound to the current context. Proc::new may be called without a block only within a method with an attached block, in which case that block is converted to the Proc object.

def proc_from
  Proc.new
end
proc = proc_from { "hello" }
proc.call   #=> "hello"

Creates a new PRNG using seed to set the initial state. If seed is omitted, the generator is initialized with Random.new_seed.

See Random.srand for more information on the use of seed values.

Creates a new Mutex

Creates a new condition variable instance.

Creates a new queue instance.

Creates a fixed-length queue with a maximum size of max.

Document-class: UncaughtThrowError

Raised when throw is called with a tag which does not have corresponding catch block.

throw "foo", "bar"

raises the exception:

UncaughtThrowError: uncaught throw "foo"

Returns a new TracePoint object, not enabled by default.

Next, in order to activate the trace, you must use TracePoint#enable

trace = TracePoint.new(:call) do |tp|
    p [tp.lineno, tp.defined_class, tp.method_id, tp.event]
end
#=> #<TracePoint:disabled>

trace.enable
#=> false

puts "Hello, TracePoint!"
# ...
# [48, IRB::Notifier::AbstractNotifier, :printf, :call]
# ...

When you want to deactivate the trace, you must use TracePoint#disable

trace.disable

See Events at TracePoint for possible events and more information.

A block must be given, otherwise an ArgumentError is raised.

If the trace method isn’t included in the given events filter, a RuntimeError is raised.

TracePoint.trace(:line) do |tp|
    p tp.raised_exception
end
#=> RuntimeError: 'raised_exception' not supported by this event

If the trace method is called outside block, a RuntimeError is raised.

TracePoint.trace(:line) do |tp|
  $tp = tp
end
$tp.lineno #=> access from outside (RuntimeError)

Access from other threads is also forbidden.

Use extend MonitorMixin or include MonitorMixin instead of this constructor. Have look at the examples above to understand how to use this module.

This string is put at the end of a line that holds a JSON array.

Duplicates self and resets its day of calendar reform.

d = Date.new(1582,10,15)
d.new_start(Date::JULIAN)         #=> #<Date: 1582-10-05 ...>

Returns OLE event object. The first argument specifies WIN32OLE object. The second argument specifies OLE event name.

ie = WIN32OLE.new('InternetExplorer.Application')
ev = WIN32OLE_EVENT.new(ie, 'DWebBrowserEvents')

Returns a new WIN32OLE_METHOD object which represents the information about OLE method. The first argument ole_type specifies WIN32OLE_TYPE object. The second argument method specifies OLE method name defined OLE class which represents WIN32OLE_TYPE object.

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

Returns WIN32OLE_PARAM object which represents OLE parameter information. 1st argument should be WIN32OLE_METHOD object. 2nd argument ‘n’ is n-th parameter of the method specified by 1st argument.

tobj = WIN32OLE_TYPE.new('Microsoft Scripting Runtime', 'IFileSystem')
method = WIN32OLE_METHOD.new(tobj, 'CreateTextFile')
param = WIN32OLE_PARAM.new(method, 2) # => #<WIN32OLE_PARAM:Overwrite=true>

Returns WIN32OLE_RECORD object. The first argument is struct name (String or Symbol). The second parameter obj should be WIN32OLE object or WIN32OLE_TYPELIB object. 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
End Class

then, you can create WIN32OLE_RECORD object is as following:

require 'win32ole'
obj = WIN32OLE.new('ComServer.ComClass')
book1 = WIN32OLE_RECORD.new('Book', obj) # => WIN32OLE_RECORD object
tlib = obj.ole_typelib
book2 = WIN32OLE_RECORD.new('Book', tlib) # => WIN32OLE_RECORD object

Returns a new WIN32OLE_TYPE object. The first argument typelib specifies OLE type library name. The second argument specifies OLE class name.

WIN32OLE_TYPE.new('Microsoft Excel 9.0 Object Library', 'Application')
    # => WIN32OLE_TYPE object of Application class of Excel.

Returns a new WIN32OLE_TYPELIB object.

The first argument typelib specifies OLE type library name or GUID or OLE library file. The second argument is major version or version of the type library. The third argument is minor version. The second argument and third argument are optional. If the first argument is type library name, then the second and third argument are ignored.

tlib1 = WIN32OLE_TYPELIB.new('Microsoft Excel 9.0 Object Library')
tlib2 = WIN32OLE_TYPELIB.new('{00020813-0000-0000-C000-000000000046}')
tlib3 = WIN32OLE_TYPELIB.new('{00020813-0000-0000-C000-000000000046}', 1.3)
tlib4 = WIN32OLE_TYPELIB.new('{00020813-0000-0000-C000-000000000046}', 1, 3)
tlib5 = WIN32OLE_TYPELIB.new("C:\\WINNT\\SYSTEM32\\SHELL32.DLL")
puts tlib1.name  # -> 'Microsoft Excel 9.0 Object Library'
puts tlib2.name  # -> 'Microsoft Excel 9.0 Object Library'
puts tlib3.name  # -> 'Microsoft Excel 9.0 Object Library'
puts tlib4.name  # -> 'Microsoft Excel 9.0 Object Library'
puts tlib5.name  # -> 'Microsoft Shell Controls And Automation'
