Sets the preset dictionary and returns string. This method is available just only after a Zlib::NeedDict exception was raised. See zlib.h for details.
Terminate the application with exit code status, running any exit handlers that might have been defined.
Terminates the RubyGems process with the given exit_code
Get the indentation level.
Set the indentation level to level. The level must be less than 10 and greater than 1.
Returns true if argument is optional.
tobj = WIN32OLE_TYPE.new('Microsoft Excel 9.0 Object Library', 'Workbook') method = WIN32OLE_METHOD.new(tobj, 'SaveAs') param1 = method.params[0] puts "#{param1.name} #{param1.optional?}" # => Filename true
Create a DRbUnknownError exception containing this object.
Sends an Options request to the server; returns an instance of a subclass of Net::HTTPResponse.
The request is based on the Net::HTTP::Options object created from string path and initial headers hash initheader.
http = Net::HTTP.new(hostname) http.options('/')

Example:
combination([:a, :b, :c, :d]) # => [[:a], [:b], [:c], [:d], [:a, :b], [:a, :c], [:a, :d], [:b, :c], [:b, :d], [:c, :d], [:a, :b, :c], [:a, :b, :d], [:a, :c, :d], [:b, :c, :d], [:a, :b, :c, :d]]
Creates a class to wrap the C union described by signature.
MyUnion = union ['int i', 'char c']
Generate a Table Caption element as a string.
align can be a string, giving the alignment of the caption (one of top, bottom, left, or right). It can be a hash of all the attributes of the element. Or it can be omitted.
The body of the element is provided by the passed-in no-argument block.
caption("left") { "Capital Cities" } # => <CAPTION ALIGN=\"left\">Capital Cities</CAPTION>
Sets OptionParser object, when opt is false or nil, methods OptionParser::Arguable#options and OptionParser::Arguable#options= are undefined. Thus, there is no ways to access the OptionParser object via the receiver object.
Actual OptionParser object, automatically created if nonexistent.
If called with a block, yields the OptionParser object and returns the result of the block. If an OptionParser::ParseError exception occurs in the block, it is rescued, a error message printed to STDERR and nil returned.
Create a new Location object
Sets the Fiber scheduler for the current thread. If the scheduler is set, non-blocking fibers (created by Fiber.new with blocking: false, or by Fiber.schedule) call that scheduler’s hook methods on potentially blocking operations, and the current thread will call scheduler’s close method on finalization (allowing the scheduler to properly manage all non-finished fibers).
scheduler can be an object of any class corresponding to Fiber::Scheduler. Its implementation is up to the user.
See also the “Non-blocking fibers” section in class docs.
Returns the Fiber scheduler, that was last set for the current thread with Fiber.set_scheduler if and only if the current fiber is non-blocking.
Adds to array all elements from each Array in other_arrays; returns self:
a = [0, 1] a.concat([2, 3], [4, 5]) # => [0, 1, 2, 3, 4, 5]
