any memberGate(string key)
This method allows the iterator to be dereferenced directly as a hash for the current row being itera...
int max()
returns the number of elements in the list
any getKeyValue(string key)
Returns the current value for the column given as an argument.
int index()
returns the current iterator position in the list or -1 if not pointing at a valid element ...
bool first()
returns True if on the first element of the list
bool empty()
returns True if the result list is empty; False if not
