Public Member Functions
virtual	~ResultImpl ()
virtual Item::Ptr	next (DynamicContext *context)=0
	Get the next item from the iterator. Returns null if the is no next value.
virtual void	skip ()
	Performs iterator specific skip of results.
virtual bool	getEffectiveBooleanValue (DynamicContext *context, const LocationInfo *info)
	Returns the effective boolean value of the sequence. Only works properly before next() has been called.
virtual Sequence	toSequence (DynamicContext *context)
	Cast operator to a Sequence. Only works properly before next() has been called.
virtual std::string	asString (DynamicContext *context, int indent) const=0
	Debug method to visualise the Result.
Static Public Member Functions
static bool	getEffectiveBooleanValue (const Item::Ptr &first, const Item::Ptr &second, DynamicContext *context, const LocationInfo *info)
	Returns the effective boolean value of the sequence.
static std::string	getIndent (int indent)
Protected Member Functions
	ResultImpl (const LocationInfo *o)
	Do not allocate this object from a memory manager! It must be created using the heap.
