Открытые методы

Метод	Описание
IsValid ( ) : bool	An iterator is either positioned at a key/value pair, or not valid.
Key ( ) : byte[]	Return the key for the current entry. REQUIRES: Valid()
KeyAsInt ( ) : int	Return the key for the current entry. REQUIRES: Valid()
KeyAsString ( ) : string	Return the key for the current entry. REQUIRES: Valid()
Next ( ) : void	Moves to the next entry in the source. After this call, Valid() is true iff the iterator was not positioned at the last entry in the source. REQUIRES: Valid()
Prev ( ) : void	Moves to the previous entry in the source. After this call, Valid() is true iff the iterator was not positioned at the first entry in source. REQUIRES: Valid()
Seek ( byte key ) : void	Position at the first key in the source that at or past target The iterator is Valid() after this call iff the source contains an entry that comes at or past target.
Seek ( int key ) : void	Position at the first key in the source that at or past target The iterator is Valid() after this call iff the source contains an entry that comes at or past target.
Seek ( string key ) : void	Position at the first key in the source that at or past target The iterator is Valid() after this call iff the source contains an entry that comes at or past target.
SeekToFirst ( ) : void	Position at the first key in the source. The iterator is Valid() after this call iff the source is not empty.
SeekToLast ( ) : void	Position at the last key in the source. The iterator is Valid() after this call iff the source is not empty.
Value ( ) : byte[]	Return the value for the current entry. REQUIRES: Valid()
ValueAsInts ( ) : int[]	Return the value for the current entry. REQUIRES: Valid()
ValueAsString ( ) : string	Return the value for the current entry. REQUIRES: Valid()
