Returns a Method of superclass which would be called when super is used or nil if there is no method on superclass.
Returns the name at the definition of the method being called.
Returns garbage collector generation for the given object.
class B include ObjectSpace def foo trace_object_allocations do obj = Object.new p "Generation is #{allocation_generation(obj)}" end end end B.new.foo #=> "Generation is 3"
See ::trace_object_allocations for more information and examples.
Parse a YAML string in yaml. Returns the Psych::Nodes::Stream. This method can handle multiple YAML documents contained in yaml. filename is used in the exception message if a Psych::SyntaxError is raised.
If a block is given, a Psych::Nodes::Document node will be yielded to the block as it’s being parsed.
Raises a Psych::SyntaxError when a YAML syntax error is detected.
Example:
Psych.parse_stream("---\n - a\n - b") # => #<Psych::Nodes::Stream:0x00> Psych.parse_stream("--- a\n--- b") do |node| node # => #<Psych::Nodes::Document:0x00> end begin Psych.parse_stream("--- `", filename: "file.txt") rescue Psych::SyntaxError => ex ex.file # => 'file.txt' ex.message # => "(file.txt): found character that cannot start any token" end
Raises a TypeError when NilClass is passed.
See Psych::Nodes for more information about YAML AST.
Glob pattern for require-able path suffixes.
The path to standard location of the user’s data directory.
The path to standard location of the user’s state directory.
Returns true if the contents of streams a and b are identical, false otherwise.
Arguments a and b should be interpretable as a path.

Returns an array of the string method names of the methods that accept the given keyword option opt; the argument must be a symbol:
FileUtils.collect_method(:preserve) # => ["cp", "copy", "cp_r", "install"]
Returns whether or not the given framework can be found on your system. If found, a macro is passed as a preprocessor constant to the compiler using the framework name, in uppercase, prepended with HAVE_FRAMEWORK_.
For example, if have_framework('Ruby') returned true, then the HAVE_FRAMEWORK_RUBY preprocessor macro would be passed to the compiler.
If fw is a pair of the framework name and its header file name that header file is checked, instead of the normally used header file which is named same as the framework.
Returns a parse result whose value is an array of tokens that closely resembles the return value of Ripper::lex. The main difference is that the ‘:on_sp` token is not emitted.
For supported options, see Prism::parse.

Sets the server hostname used for SNI. This needs to be set before SSLSocket#connect.
Fetch the filepath of the value.
Configure the filepath field for this repository and return self.
The name of this activation request’s specification
The name of the gem this dependency request is requesting.
The name of the gem for this specification
Returns the file name of this frame. This will generally be an absolute path, unless the frame is in the main script, in which case it will be the script location passed on the command line.
For example, using caller_locations.rb from Thread::Backtrace::Location
loc = c(0..1).first loc.path #=> caller_locations.rb
Indicated whether this Cipher instance uses an Authenticated Encryption mode.
returns the timestamp as a time object.
ancillarydata should be one of following type:
SOL_SOCKET/SCM_TIMESTAMP (microsecond) GNU/Linux, FreeBSD, NetBSD, OpenBSD, Solaris, MacOS X
SOL_SOCKET/SCM_TIMESTAMPNS (nanosecond) GNU/Linux
SOL_SOCKET/SCM_BINTIME (2**(-64) second) FreeBSD
Addrinfo.udp(“127.0.0.1”, 0).bind {|s1|
Addrinfo.udp("127.0.0.1", 0).bind {|s2| s1.setsockopt(:SOCKET, :TIMESTAMP, true) s2.send "a", 0, s1.local_address ctl = s1.recvmsg.last p ctl #=> #<Socket::AncillaryData: INET SOCKET TIMESTAMP 2009-02-24 17:35:46.775581> t = ctl.timestamp p t #=> 2009-02-24 17:35:46 +0900 p t.usec #=> 775581 p t.nsec #=> 775581000 }
