parsePrototype()

void VHDLOutlineParser::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.
