A pre-scanned Markdown statement.
| def Plugins.Content.Parse.Semantic.MarkdownPreStatements.APrescannedMarkdownStatement.handlerFor | ( | Self, | |
| tokenCode, | |||
| params | |||
| ) |
Determine whether the class will handle the specified token.
Together with APrescannedMarkdownStatement.subclassHandlerFor(), this method makes adding new handlers for Markdown tokens as easy as deriving a class from APrescannedMarkdownStatement or its descendants.
The base implementation of this method searches the immediate subclasses of APrescannedMarkdownStatement, calling AMarkdownStatement.handlerFor() on each one. THOSE classes, in turn, first determine whether or not they will handle tokenCode. If not, they search their immediate subclasses (by calling AMarkdownStatement.subclassHandlerFor() on themselves) – and so forth.
The base implementation of this method returns the result of call to APrescannedMarkdownStatement.subclassHandlerFor() on itself. The return value will either be an instance of the class that will handle the specified tokenCode; or None to indicate that no class was found to handle the specified token.
Descendant classes should override this method to add code that will determine whether or not the class will handle the specified token. Otherwise, the overriding method should return the result of a call to APrescannedMarkdownStatement.subclassHandlerFor() on its class.
| def Plugins.Content.Parse.Semantic.MarkdownPreStatements.APrescannedMarkdownStatement.subclassHandlerFor | ( | Self, | |
| tokenCode, | |||
| params | |||
| ) |
Search subclasses for the handler for the specified token.
This method takes advantage of the fact that Python links the immediate subclasses of a class to their parent using an iterable object. The method iterates through those subclasses, calling APrescannedMarkdownStatement.handlerFor() on each one in an attempt to find a class that will handle the specified tokenCode.
If a class determines that it will handle the specified tokenCode, it creates an instance of itself and returns that instance instead of continuing the search. That instance will be returned by this method, which otherwise returns None to indicate that no class was found to handle the specified tokenCode.
