Gets the option name to turn on this add-on.
For example, if "abc" is returned, "-abc" will turn on this plugin. A plugin needs to be turned on explicitly, or else no other methods of Plugin will be invoked.
When an option matches the name returned from this method, WsImport will then invoke parseArgument(Options, String[], int), allowing plugins to handle arguments to this option.

public abstract String getUsage();
Parses an option args[i] and augment the opt object
appropriately, then return the number of tokens consumed.
The callee doesn't need to recognize the option that the
getOptionName method returns.
Once a plugin is activated, this method is called for options that
WsImport didn't recognize. This allows a plugin to define additional
options to customize its behavior.
Since options can appear in no particular order, WsImport allows sub-options of a plugin to show up before the option that activates a plugin (one that's returned by getOptionName().) But nevertheless a Plugin needs to be activated to participate in further processing.
Throws: - BadCommandLineException – If the option was recognized but
there's an error. This halts the argument parsing process and causes
WsImport to abort, reporting an error.
Returns: 0 if the argument is not understood. Otherwise return the number
of tokens that are consumed, including the option itself. (so if you have
an option like "-foo 3", return 2.)

Run the add-on.
This method is invoked after WsImport has internally finished the code generation. Plugins can tweak some of the generated code (or add more code) by altering JCodeModel obtained from WsimportOptions.getCodeModel() according to the current WSDL model and WsimportOptions.
Note that this method is invoked only when a Plugin is activated.
Params: - wsdlModel – This object allows access to the WSDL model used for
code generation.
- options – This object allows access to various options used for code
generation as well as access to the generated code.
- errorReceiver – Errors should be reported to this handler.
Throws: - SAXException – After an error is reported to
ErrorReceiver, the same exception can be thrown to indicate a fatal irrecoverable error. ErrorReceiver itself may throw it, if it chooses not to recover from the error.
Returns: If the add-on executes successfully, return true. If it detects
some errors but those are reported and recovered gracefully, return
false.
