SOCKS is an Internet protocol that routes packets between a client and a server through a proxy server. SOCKS5, if supported, additionally provides authentication so only authorized users may access a server.

OLEProperty helper class of Property with arguments.

This class implements a pretty printing algorithm. It finds line breaks and nice indentations for grouped structure.

By default, the class assumes that primitive elements are strings and each byte in the strings have single column in width. But it can be used for other situations by giving suitable arguments for some methods:

• newline object and space generation block for PrettyPrint.new

• optional width argument for PrettyPrint#text

• PrettyPrint#breakable

There are several candidate uses:

• text formatting using proportional fonts

• multibyte characters which has columns different to number of bytes

• non-string formatting

Bugs

• Box based formatting?

• Other (better) model/algorithm?

Raised when attempting to divide an integer by 0.

42 / 0   #=> ZeroDivisionError: divided by 0

Note that only division by an exact 0 will raise the exception:

42 /  0.0   #=> Float::INFINITY
42 / -0.0   #=> -Float::INFINITY
0  /  0.0   #=> NaN

Raised when Ruby can’t yield as requested.

A typical scenario is attempting to yield when no block is given:

def call_block
  yield 42
end
call_block

raises the exception:

LocalJumpError: no block given (yield)

A more subtle example:

def get_me_a_return
  Proc.new { return 42 }
end
get_me_a_return.call

raises the exception:

LocalJumpError: unexpected return

Raised when throw is called with a tag which does not have corresponding catch block.

throw "foo", "bar"

raises the exception:

UncaughtThrowError: uncaught throw "foo"

Returns the octet string representation of the elliptic curve point.

Subclass of Zlib::Error. This error is raised when the zlib stream is currently in progress.

end

Raised when the address is an invalid length.

TupleSpaceProxy allows a remote Tuplespace to appear as local.

RingProvider uses a RingServer advertised TupleSpace as a name service. TupleSpace clients can register themselves with the remote TupleSpace and look up other provided services via the remote TupleSpace.

Services are registered with a tuple of the format [:name, klass, DRbObject, description].
