Sends a PROPPATCH request to the path and gets a response, as an HTTPResponse object.
Sends a PROPFIND request to the path and gets a response, as an HTTPResponse object.
Advertises this service on the primary remote TupleSpace.
Returns the list of protected methods accessible to obj. If the all parameter is set to false, only those methods in the receiver will be listed.
Receives up to maxlen bytes from socket using recvfrom(2) after O_NONBLOCK is set for the underlying file descriptor. flags is zero or more of the MSG_ options. The first element of the results, mesg, is the data received. The second element, sender_addrinfo, contains protocol-specific address information of the sender.
When recvfrom(2) returns 0, Socket#recvfrom_nonblock returns an empty string as data. The meaning depends on the socket: EOF on TCP, empty packet on UDP, etc.
maxlen - the maximum number of bytes to receive from the socket
flags - zero or more of the MSG_ options
outbuf - destination String buffer
opts - keyword hash, supporting ‘exception: false`

Refer to Socket#recvfrom for the exceptions that may be thrown if the call to recvfrom_nonblock fails.
Socket#recvfrom_nonblock may raise any error corresponding to recvfrom(2) failure, including Errno::EWOULDBLOCK.
If the exception is Errno::EWOULDBLOCK or Errno::EAGAIN, it is extended by IO::WaitReadable. So IO::WaitReadable can be used to rescue the exceptions for retrying recvfrom_nonblock.
By specifying a keyword argument exception to false, you can indicate that recvfrom_nonblock should not raise an IO::WaitReadable exception, but return the symbol :wait_readable instead.
Receives up to maxlen bytes from udpsocket using recvfrom(2) after O_NONBLOCK is set for the underlying file descriptor. flags is zero or more of the MSG_ options. The first element of the results, mesg, is the data received. The second element, sender_inet_addr, is an array to represent the sender address.
When recvfrom(2) returns 0, Socket#recvfrom_nonblock returns an empty string as data. It means an empty packet.

Returns the methods available to this delegate object as the union of this object’s and _getobj_ protected methods.
Returns the inner product of this vector with the other.
Vector[4,7].inner_product Vector[10,1] => 47
Program name to be emitted in error message and default banner, defaults to $0.
Returns true if the set is a proper superset of the given set.
Returns true if the set is a proper subset of the given set.
Returns the number of malloc() allocations.
Only available if ruby was built with CALC_EXACT_MALLOC_SIZE.

Returns a list of the protected instance methods defined in mod. If the optional parameter is false, the methods of any ancestors are not included.
Returns true if the named protected method is defined by mod (or its included modules and, if mod is a class, its ancestors). String arguments are converted to symbols.
module A def method1() end end class B protected def method2() end end class C < B include A def method3() end end A.method_defined? :method1 #=> true C.protected_method_defined? "method1" #=> false C.protected_method_defined? "method2" #=> true C.method_defined? "method2" #=> true
