Clear the reference to the object this is pinning.
Returns true if the reference has been cleared, otherwise returns false.
Generates a cryptographically strong pseudo-random number of bits.
See also the man page BN_rand(3).
Parses a given string as a blob that contains configuration for OpenSSL.
Emit a scalar with value
Called when a scalar value is found. The scalar may have an anchor, a tag, be implicitly plain or implicitly quoted
value is the string value of the scalar anchor is an associated anchor or nil tag is an associated tag or nil plain is a boolean value quoted is a boolean value style is an integer indicating the string style
See the constants in Psych::Nodes::Scalar for the possible values of style
Here is a YAML document that exercises most of the possible ways this method can be called:
--- - !str "foo" - &anchor fun - many lines - | many newlines
The above YAML document contains a list with four strings. Here are the parameters sent to this method in the same order:
# value anchor tag plain quoted style ["foo", nil, "!str", false, false, 3 ] ["fun", "anchor", nil, true, false, 1 ] ["many lines", nil, nil, true, false, 1 ] ["many\nnewlines\n", nil, nil, false, true, 4 ]
Parse the YAML document contained in yaml. Events will be called on the handler set on the parser instance.
See Psych::Parser and Psych::Parser#handler
Returns a Psych::Parser::Mark object that contains line, column, and index information.
Emit a scalar with value, anchor, tag, and a plain or quoted string type with style.
Enter error recovering mode. This method does not call on_error.
Leave error recovering mode.
Starts the parser. init is a data accumulator and is passed to the next event handler (as of Enumerable#inject).
Logs a message at the error (syslog warning) log level, or logs the message returned from the block.
Logs a message at the warn (syslog notice) log level, or logs the message returned from the block.
Creates a GzipReader or GzipWriter associated with io, passing in any necessary extra options, and executes the block with the newly created object just like File.open.
The GzipFile object will be closed automatically after executing the block. If you want to keep the associated IO object open, you may call Zlib::GzipFile#finish method in the block.
Reads at most maxlen bytes from the gziped stream but it blocks only if gzipreader has no data immediately available. If the optional outbuf argument is present, it must reference a String, which will receive the data. It raises EOFError on end of file.
See Zlib::GzipReader documentation for a description.
Returns true if the file is a character device, false if it isn’t or if the operating system doesn’t support this feature.
File.stat("/dev/tty").chardev? #=> true
Transfers ownership to a new buffer, deallocating the current one.
buffer = IO::Buffer.new('test') other = buffer.transfer other # => # #<IO::Buffer 0x00007f136a15f7b0+4 SLICE> # 0x00000000 74 65 73 74 test buffer # => # #<IO::Buffer 0x0000000000000000+0 NULL> buffer.null? # => true
Fill buffer with value, starting with offset and going for length bytes.
buffer = IO::Buffer.for('test') # => # <IO::Buffer 0x00007fca40087c38+4 SLICE> # 0x00000000 74 65 73 74 test buffer.clear # => # <IO::Buffer 0x00007fca40087c38+4 SLICE> # 0x00000000 00 00 00 00 .... buf.clear(1) # fill with 1 # => # <IO::Buffer 0x00007fca40087c38+4 SLICE> # 0x00000000 01 01 01 01 .... buffer.clear(2, 1, 2) # fill with 2, starting from offset 1, for 2 bytes # => # <IO::Buffer 0x00007fca40087c38+4 SLICE> # 0x00000000 01 02 02 01 .... buffer.clear(2, 1) # fill with 2, starting from offset 1 # => # <IO::Buffer 0x00007fca40087c38+4 SLICE> # 0x00000000 01 02 02 02 ....
Parse a raw cookie string into a hash of cookie-name=>Cookie pairs.
cookies = CGI::Cookie.parse("raw_cookie_string") # { "name1" => cookie1, "name2" => cookie2, ... }
