Method Details

setProtocol

public static void setProtocol(Protocol oProtocol)

Sets (adds) the given protocol to the list of protocol handlers.

Parameters:

oProtocol - a protocol handler. Subsequent to this operation, the I/O of any URL whose scheme matches the given protocol will be routed to the given protocol handler.

resetProtocols

public static void resetProtocols()

Uninstall all protocol handlers. It is normally not necessary to make this call, as protocol handlers are automatically deleted on exit. However, when a protocol handler is in a DLL that is dynamically loaded, it is possible for that DLL to be unloaded before the automatic deletion takes place, leading to a crash. In that case the DLL must call ResetProtocols just prior to unloading (for example in the destructor of a global variable).

getProtocol

public static Protocol getProtocol(String sScheme)

Get the currently installed protocol handler associated with the given scheme.

Parameters:

sScheme - a URL's scheme.

Returns:

the matching protocol handler.

crackUrl

public static void crackUrl(String sUrl,
 StringHolder sScheme,
 StringHolder sUser,
 StringHolder sPwd,
 StringHolder sHost,
 StringHolder sPort,
 StringHolder sPath)

Crack an url into its constituent parts. The URL is cracked from the following rule:

     scheme://[user[:password]@]host[:port][/path]
 

Parameters:

sUrl - the URL to crack.

sScheme - the cracked URL's scheme.

sUser - the cracked URL's user, if any.

sPwd - the cracked URL's password, if any.

sHost - the cracked URL's host.

sPort - the cracked URL's port, if any.

sPath - the cracked URL's path, if any.

canonUrl

public static String canonUrl(String sScheme,
 String sHost,
 String sPort,
 String sPath)

Canon(ize) an url into its constituent parts. The URL is canonized into the following rule:

     scheme://host[:port][/path]
 

Parameters:

sScheme - the URL's scheme.

sHost - the URL's host.

sPort - the URL's port, if any.

sPath - the URL's path, if any.

Returns:

The canonized URL.

urlEncode

public static String urlEncode(String sUrl)

URL encode a string

Parameters:

sUrl - string to be encoded

Returns:

URL encoded string

urlDecode

public static String urlDecode(String sUrl)

Decode a URL encoded string

Parameters:

sUrl - string to be decoded
