The parameter string that describes the target should conform to the URL format as described in RFC 2396. This takes the general form: <p> <code>{scheme}:[{target}][{parms}]</code> <p> where <code>{scheme}</code> is the name of a protocol such as <i>http</i>. <p> The <code>{target}</code> is normally some kind of network address. <p> Any <code>{parms}</code> are formed as a series of equates of the form ";x=y". Example: ";type=a". <p> An optional second parameter may be specified to the open function. This is a mode flag that indicates to the protocol handler the intentions of the calling code. The options here specify if the connection is going to be read (READ), written (WRITE), or both (READ_WRITE). The validity of these flag settings is protocol dependent. For instance, a connection for a printer would not allow read access, and would throw an IllegalArgumentException. If the mode parameter is not specified, READ_WRITE is used by default. <p> An optional third parameter is a boolean flag that indicates if the calling code can handle timeout exceptions. If this flag is set, the protocol implementation may throw an InterruptedIOException when it detects a timeout condition. This flag is only a hint to the protocol handler, and it does not guarantee that such exceptions will actually be thrown. If this parameter is not set, no timeout exceptions will be thrown. <p> Because connections are frequently opened just to gain access to a specific input or output stream, four convenience functions are provided for this purpose.
