parsePrototype()

void MarkdownOutlineParser::parsePrototype ( const QCString & text )

overridevirtual

Callback function called by the comment block scanner.

It provides a string text containing the prototype of a function or variable. The parser should parse this and store the information in the Entry node that corresponds with the node for which the comment block parser was invoked.

Implements OutlineParserInterface.
