Member Function Documentation

BoolExpr<std::string>* boolstuff::BoolExprParser::parse (  const std::string &  expr  )  throw (Error)

Parses a textual boolean expression and creates a binary syntax tree. Dynamically allocates a tree of nodes that represents the syntactic structure of 'expr'. The returned tree must eventually be destroyed with operator delete. Parameters: expr  text of the boolean expression to parse Returns: the root of the created tree Exceptions: Error  describes a parsing error
