virtual const Token* ExecutionPath::parse ( const Token &  tok, std::list< ExecutionPath * > &  checks  ) const

pure virtual

Parse tokens at given location.

Parameters

tok	token to parse
checks	The execution paths. All execution paths in the list are executed in the current scope.

Returns

the token before the "next" token.

bool ExecutionPath::parseCondition ( const Token &  tok, std::list< ExecutionPath * > &  checks  )

virtual

Parse condition.

Parameters

tok	first token in condition.
checks	The execution paths. All execution paths in the list are executed in the current scope

Returns

true => bail out all checking

Parameters

tok	the first token in the loop body (the token after the {)
checks	The execution paths
