#include <QoreHashNode.h>
Public Member Functions | |
| DLLEXPORT | ReverseHashIterator (QoreHashNode *h) |
| initializes the iterator with the passed hash | |
| DLLEXPORT | ReverseHashIterator (QoreHashNode &h) |
| initializes the iterator with the passed hash | |
| DLLEXPORT | ~ReverseHashIterator () |
| Destroys the iterator. | |
| DLLEXPORT bool | first () const |
| returns true if on the last key of the hash | |
| DLLEXPORT bool | last () const |
| returns true if on the first key of the hash | |
| DLLEXPORT bool | next () |
| moves to the next element in reverse order, returns false when there are no more elements to iterate More... | |
| DLLEXPORT bool | prev () |
| moves to the previous element in reverse order, returns false when there are no more elements to iterate More... | |
 Public Member Functions inherited from HashIterator | |
| DLLEXPORT | HashIterator (QoreHashNode *h) |
| initializes the iterator with the passed hash | |
| DLLEXPORT | HashIterator (QoreHashNode &h) |
| initializes the iterator with the passed hash | |
| DLLEXPORT | ~HashIterator () |
| Destroys the iterator. | |
| DLLEXPORT void | deleteKey (ExceptionSink *xsink) |
| deletes the key from the hash and dereferences the value More... | |
| DLLEXPORT bool | empty () const |
| returns true if the hash is empty | |
| DLLEXPORT bool | first () const |
| returns true if on the first key of the hash | |
| DLLEXPORT const char * | getKey () const |
| returns the current key | |
| DLLEXPORT QoreString * | getKeyString () const |
| returns a QoreString for the current key, the caller owns QoreString returned | |
| DLLEXPORT AbstractQoreNode * | getReferencedValue () const |
| returns the value of the current key with an incremented reference count | |
| DLLEXPORT AbstractQoreNode * | getValue () const |
| returns the value of the current key | |
| DLLEXPORT AbstractQoreNode ** | getValuePtr () const |
| returns a pointer to a pointer to the current value so the value of the key may be manipulated externally More... | |
| DLLEXPORT bool | last () const |
| returns true if on the last key of the hash | |

| moves to the previous element, returns false when there are no more elements to iterate More... | |
| DLLEXPORT AbstractQoreNode * | takeValueAndDelete () |
| deletes the key from the hash and returns the value, caller owns the reference | |
| DLLEXPORT bool | valid () const |
| returns true if the iterator is currently pointing at a valid element | |

reverse iterator class for QoreHashNode, to be only created on the stack
| DLLEXPORT bool ReverseHashIterator::next | ( | ) |
moves to the next element in reverse order, returns false when there are no more elements to iterate
also moves to the last element if the object has just been initialized after a complete iteration (assuming there is at least one element in the hash)
| DLLEXPORT bool ReverseHashIterator::prev | ( | ) |
moves to the previous element in reverse order, returns false when there are no more elements to iterate
also moves to the first element if the object has just been initialized after a complete iteration (assuming there is at least one element in the hash)
