Methods
canonify()
convertChromeURL() instead.Converts a chrome URL into a canonical representation by ensuring that the filename portion of the URL is included, as in chrome://package/provider/file. This is useful because chrome URLs are allowed to be specified in "shorthand", leaving the "file" portion off. In that case, the URL is expanded to chrome://package/provider/package.ext.
The extension, ext, is one of:
- xul
- For a "content" package.
- css
- For a "skin" package.
- dtd
- For a "locale" package.
void canonify( in nsIURI aChromeURL );
Parameters
-
aChromeURL - The URL that is to be canonified.
checkForNewChrome()
Refreshes the chrome list at runtime, looking for new packages and so forth.
void checkForNewChrome();
Parameters
None.
convertChromeURL()
Resolves a chrome URL to an loadable URI using the information in the registry. A new nsIURI is returned; the original is left unmodified.
This lets you take a non-canonical chrome URI, such as chrome://package/provider/file, and convert it into a canonical one. This is useful because chrome URLs are allowed to be specified in "shorthand", leaving the "file" portion off. In that case, the URL is expanded to chrome://package/provider/package.ext.
The extension, ext, is one of:
- xul
- For a "content" package.
- css
- For a "skin" package.
- dtd
- For a "locale" package.
nsIURI convertChromeURL( in nsIURI aChromeURL );
Parameters
-
aChromeURL - The URL that is to be converted.
Return value
A new nsIURI object containing the loadable URI for the specified chrome URL.
wrappersEnabled()
Returns whether XPCNativeWrappers are enabled for the specified URI.
boolean wrappersEnabled( in nsIURI aURI );
Parameters
-
aURI - The URI for which to determine if XPCNativeWrappers are enabled.
Return value
true if XPCNativeWrappers are enabled for the specified URI; otherwise false.
