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
, a checksum of the data, and the size of the data.
The path to standard location of the user’s data directory.
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
: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
Sets the length of the plaintext / ciphertext message that will be processed in CCM mode. Make sure to call this method after key=
and iv=
have been set, and before auth_data=
.
Only call this method after calling Cipher#encrypt
or Cipher#decrypt
.
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"}, ';')
Verifies that data
matches the signature
created by public_key
and the digest
algorithm.
Returns the concatenated string from strings
.
Load extra data embed into binary format String
object.
