Known Subclasses:

An ADQLNodes having a function name and arguments.

The rules having this as action must use the Arg "decorator" in grammar.py around their arguments and must have a string-valued result "fName".

FunctionNodes have attributes args (unflattened arguments), and funName (a string containing the function name, all upper case).

Method Details

flatten(self)

source code

returns a string representation of the text content of the tree.

This default implementation will only work if you returned all parsed elements as children. This, in turn, is something you only want to do if you are sure that the node is question will not be morphed.

Otherwise, override it to create an SQL fragment out of the parsed attributes.
