Initializes a new servlet for server using options which are stored as-is in +@options+. +@logger+ is also provided.

Creates a new CGI script servlet for the script at name

Creates a new ERBHandler on server that will evaluate and serve the ERB file name

Creates a DefaultFileHandler instance for the file at local_path.

Creates a FileHandler servlet on server that serves files starting at directory root

options may be a Hash containing keys from WEBrick::Config::FileHandler or true or false.

If options is true or false then :FancyIndexing is enabled or disabled respectively.

Creates a new FormData object.

args is an Array of form data entries. One FormData will be created for each entry.

This is called by WEBrick::HTTPUtils.parse_form_data for you

Creates a new TimeoutHandler. You should use ::register and ::cancel instead of creating the timeout handler directly.

Create a new streaming emitter. Emitter will print to io. See Psych::Stream for an example.

The most standard error types are subclasses of StandardError. A rescue clause without an explicit Exception class will rescue all StandardErrors (and only those).

def foo
  raise "Oups"
end
foo rescue "Hello"   #=> "Hello"

On the other hand:

require 'does/not/exist' rescue "Hi"

raises the exception:

LoadError: no such file to load -- does/not/exist

Raised when the arguments are wrong and there isn’t a more specific Exception class.

Ex: passing the wrong number of arguments

[1, 2, 3].first(4, 5)

raises the exception:

ArgumentError: wrong number of arguments (given 2, expected 1)

Ex: passing an argument that is not acceptable:

[1, 2, 3].first(-4)

raises the exception:

ArgumentError: negative array size

Raised when a given numerical value is out of range.

[1, 2, 3].drop(1 << 100)

raises the exception:

RangeError: bignum too big to convert into `long'

Raised when there is an attempt to modify a frozen object.

[1, 2, 3].freeze << 4

raises the exception:

FrozenError: can't modify frozen Array

Raised when attempting to divide an integer by 0.

42 / 0   #=> ZeroDivisionError: divided by 0

Note that only division by an exact 0 will raise the exception:

42 /  0.0   #=> Float::INFINITY
42 / -0.0   #=> -Float::INFINITY
0  /  0.0   #=> NaN

Raised when attempting to convert special float values (in particular Infinity or NaN) to numerical classes which don’t support them.

Float::INFINITY.to_r   #=> FloatDomainError: Infinity

The Comparable mixin is used by classes whose objects may be ordered. The class must define the <=> operator, which compares the receiver against another object, returning -1, 0, or +1 depending on whether the receiver is less than, equal to, or greater than the other object. If the other object is not comparable then the <=> operator should return nil. Comparable uses <=> to implement the conventional comparison operators (<, <=, ==, >=, and >) and the method between?.

class SizeMatters
  include Comparable
  attr :str
  def <=>(other)
    str.size <=> other.str.size
  end
  def initialize(str)
    @str = str
  end
  def inspect
    @str
  end
end

s1 = SizeMatters.new("Z")
s2 = SizeMatters.new("YY")
s3 = SizeMatters.new("XXX")
s4 = SizeMatters.new("WWWW")
s5 = SizeMatters.new("VVVVV")

s1 < s2                       #=> true
s4.between?(s1, s3)           #=> false
s4.between?(s3, s5)           #=> true
[ s3, s2, s5, s4, s1 ].sort   #=> [Z, YY, XXX, WWWW, VVVVV]

An Array wrapper that can be sent to another server via DRb.

All entries in the array will be dumped or be references that point to the local server.

An implementation of PseudoPrimeGenerator.

Uses EratosthenesSieve.

WIN32OLE_PARAM objects represent param information of the OLE method.

This exception is raised if a generator or unparser error occurs.

Raised by Encoding and String methods when a transcoding operation fails.
