Request query as a Hash
Services req and fills in res
Converts version into an HTTPVersion
Closes the logger (also closes the log device associated to the logger)
Shortcut for logging an ERROR message
Will the logger output ERROR messages?
Returns a Hash (not a DBM database) created by using each value in the database as a key, with the corresponding key as its value.
Note that all values in the hash will be Strings, but the keys will be actual objects.
Returns the number of the signal that caused stat to terminate (or nil if self was not terminated by an uncaught signal).
Returns true if this lock is currently held by some thread.
Attempts to grab the lock and waits if it isn’t available. Raises ThreadError if mutex was locked by the current thread.
Releases the lock. Raises ThreadError if mutex wasn’t locked by the current thread.
Closes the queue. A closed queue cannot be re-opened.
After the call to close completes, the following are true:
closed? will return true
close will be ignored.
calling enq/push/<< will return nil.
when empty? is false, calling deq/pop/shift will return an object from the queue as usual.
ClosedQueueError is inherited from StopIteration, so that you can break loop block.
Example:
q = Queue.new
Thread.new{
while e = q.deq # wait for nil to break loop
# ...
end
}
q.close
Returns true if the queue is closed.
Similar to Queue#close.
The difference is behavior with waiting enqueuing threads.
If there are waiting enqueuing threads, they are interrupted by raising ClosedQueueError(‘queue closed’).
Convert source_string and return destination_string.
source_string is assumed as a part of source. i.e. :partial_input=>true is specified internally. finish method should be used last.
ec = Encoding::Converter.new("utf-8", "euc-jp") puts ec.convert("\u3042").dump #=> "\xA4\xA2" puts ec.finish.dump #=> "" ec = Encoding::Converter.new("euc-jp", "utf-8") puts ec.convert("\xA4").dump #=> "" puts ec.convert("\xA2").dump #=> "\xE3\x81\x82" puts ec.finish.dump #=> "" ec = Encoding::Converter.new("utf-8", "iso-2022-jp") puts ec.convert("\xE3").dump #=> "".force_encoding("ISO-2022-JP") puts ec.convert("\x81").dump #=> "".force_encoding("ISO-2022-JP") puts ec.convert("\x82").dump #=> "\e$B$\"".force_encoding("ISO-2022-JP") puts ec.finish.dump #=> "\e(B".force_encoding("ISO-2022-JP")
If a conversion error occur, Encoding::UndefinedConversionError or Encoding::InvalidByteSequenceError is raised. Encoding::Converter#convert doesn’t supply methods to recover or restart from these exceptions. When you want to handle these conversion errors, use Encoding::Converter#primitive_convert.
If none is given, returns the resulting hash value of the digest, keeping the digest’s state.
If a string is given, returns the hash value for the given string, resetting the digest to the initial state before and after the process.
Returns the resulting hash value and resets the digest to the initial state.
If none is given, returns the resulting hash value of the digest in a hex-encoded form, keeping the digest’s state.
If a string is given, returns the hash value for the given string in a hex-encoded form, resetting the digest to the initial state before and after the process.
Returns the resulting hash value in a hex-encoded form and resets the digest to the initial state.
If none is given, returns the resulting hash value of the digest in a base64 encoded form, keeping the digest’s state.
If a string is given, returns the hash value for the given string in a base64 encoded form, resetting the digest to the initial state before and after the process.
In either case, the return value is properly padded with ‘=’ and contains no line feeds.
Returns the resulting hash value and resets the digest to the initial state.
Creates an array of handlers for the given libs, can be an instance of Fiddle::Handle, Fiddle::Importer, or will create a new instance of Fiddle::Handle using Fiddle.dlopen
Raises a DLError if the library cannot be loaded.
See Fiddle.dlopen
Creates a global method from the given C signature.
The Fiddle::CompositeHandler instance
Will raise an error if no handlers are open.
