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

Starts tracing object allocations.

Stop tracing object allocations.

Note that if ::trace_object_allocations_start is called n-times, then tracing will stop after calling ::trace_object_allocations_stop n-times.

The iterator version of the strongly_connected_components method. obj.each_strongly_connected_component is similar to obj.strongly_connected_components.each, but modification of obj during the iteration may lead to unexpected results.

each_strongly_connected_component returns nil.

The iterator version of the TSort.strongly_connected_components method.

The graph is represented by each_node and each_child. each_node should have call method which yields for each node in the graph. each_child should have call method which takes a node argument and yields for each child node.

g = {1=>[2, 3], 2=>[4], 3=>[2, 4], 4=>[]}
each_node = lambda {|&b| g.each_key(&b) }
each_child = lambda {|n, &b| g[n].each(&b) }
TSort.each_strongly_connected_component(each_node, each_child) {|scc| p scc }
#=> [4]
#   [2]
#   [3]

Get the indentation level.

Set the indentation level to level. The level must be less than 10 and greater than 1.

Create a DRbUnknownError exception containing this object.

Sends a OPTIONS request to the path and gets a response, as an HTTPResponse object.

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.

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]
