Results for: "Data"

This is a recommended base class for C extensions using Data_Make_Struct or Data_Wrap_Struct, see README.EXT for details.

Load the given PStore file. If read_only is true, the unmarshalled Hash will be returned. If read_only is false, a 3-tuple will be returned: the unmarshalled Hash, an MD5 checksum of the data, and the size of the data.

returns the cmsg data as a string.

p Socket::AncillaryData.new(:INET6, :IPV6, :PKTINFO, "").data
#=> ""

returns the socket option data as a string.

p Socket::Option.new(:INET6, :IPV6, :RECVPKTINFO, [1].pack("i!")).data
#=> "\x01\x00\x00\x00"

This method sends a message. If msgstr is given, sends it as a message. If block is given, yield a message writer stream. You must write message before the block is closed.

# Example 1 (by string)
smtp.data(<<EndMessage)
From: john@example.com
To: betty@example.com
Subject: I found a bug

Check vm.c:58879.
EndMessage

# Example 2 (by block)
smtp.data {|f|
  f.puts "From: john@example.com"
  f.puts "To: betty@example.com"
  f.puts "Subject: I found a bug"
  f.puts ""
  f.puts "Check vm.c:58879."
}

Guesses the type of the data which have been inputed into the stream. The returned value is either BINARY, ASCII, or UNKNOWN.

Returns an Array of individual raw profile data Hashes ordered from earliest to latest by :GC_INVOKE_TIME.

For example:

[
  {
     :GC_TIME=>1.3000000000000858e-05,
     :GC_INVOKE_TIME=>0.010634999999999999,
     :HEAP_USE_SIZE=>289640,
     :HEAP_TOTAL_SIZE=>588960,
     :HEAP_TOTAL_OBJECTS=>14724,
     :GC_IS_MARKED=>false
  },
  # ...
]

The keys mean:

:GC_TIME

Time elapsed in seconds for this GC run

:GC_INVOKE_TIME

Time elapsed in seconds from startup to when the GC was invoked

:HEAP_USE_SIZE

Total bytes of heap used

:HEAP_TOTAL_SIZE

Total size of heap in bytes

:HEAP_TOTAL_OBJECTS

Total number of objects

:GC_IS_MARKED

Returns true if the GC is in mark phase

If ruby was built with GC_PROFILE_MORE_DETAIL, you will also have access to the following hash keys:

:GC_MARK_TIME

:GC_SWEEP_TIME

:ALLOCATE_INCREASE

:ALLOCATE_LIMIT

:HEAP_USE_PAGES

:HEAP_LIVE_OBJECTS

:HEAP_FREE_OBJECTS

:HAVE_FINALIZE

Set header fields and a body from HTML form data. params should be an Array of Arrays or a Hash containing HTML form data. Optional argument sep means data record separator.

Values are URL encoded as necessary and the content-type is set to application/x-www-form-urlencoded

Example:

http.form_data = {"q" => "ruby", "lang" => "en"}
http.form_data = {"q" => ["ruby", "perl"], "lang" => "en"}
http.set_form_data({"q" => "ruby", "lang" => "en"}, ';')

Parses form data in io with the given boundary

Parses form data in io with the given boundary

Verifies that data matches the signature created by public_key and the digest algorithm.

Adds data at the end of the chain of entries

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