namespaceUri
- the extension namespace URI that I'm implementingelemNames
- Vector of element namesfuncNames
- string containing list of functions of extension NSlang
- language of code implementing the extensionsrcURL
- value of src attribute (if any) - treated as a URL
or a classname depending on the value of lang. If
srcURL is not null, then scriptSrc is ignored.scriptLang
- Scripting language of implementationscriptSrcURL
- URL of source scriptscriptSrc
- the actual script code (if any)Method Detail |
