    #   URI::Parser.new([opts])
 | 
						|
    #
 | 
						|
    # == Args
 | 
						|
    #
 | 
						|
    # The constructor accepts a hash as options for parser.
 | 
						|
    # Keys of options are pattern names of URI components
 | 
						|
    # and values of options are pattern strings.
 | 
						|
    # The constructor generetes set of regexps for parsing URIs.
 | 
						|
    #
 | 
						|
    # You can use the following keys:
 | 
						|
    #
 | 
						|
    #   * :ESCAPED (URI::PATTERN::ESCAPED in default)
 | 
						|
    #   * :UNRESERVED (URI::PATTERN::UNRESERVED in default)
 | 
						|
    #   * :DOMLABEL (URI::PATTERN::DOMLABEL in default)
 | 
						|
    #   * :TOPLABEL (URI::PATTERN::TOPLABEL in default)
 | 
						|
    #   * :HOSTNAME (URI::PATTERN::HOSTNAME in default)
 | 
						|
    #
 | 
						|
    # == Examples
 | 
						|
    #
 | 
						|
    #   p = URI::Parser.new(:ESCAPED => "(?:%[a-fA-F0-9]{2}|%u[a-fA-F0-9]{4})")
 | 
						|
    #   u = p.parse("http://example.jp/%uABCD") #=> #<URI::HTTP:0xb78cf4f8 URL:http://example.jp/%uABCD>
 | 
						|
    #   URI.parse(u.to_s) #=> raises URI::InvalidURIError
 | 
						|
    #
 | 
						|
    #   s = "http://examle.com/ABCD"
 | 
						|
    #   u1 = p.parse(s) #=> #<URI::HTTP:0xb78c3220 URL:http://example.com/ABCD>
 | 
						|
    #   u2 = URI.parse(s) #=> #<URI::HTTP:0xb78b6d54 URL:http://example.com/ABCD>
