Detailed Description

constant iterator class for QoreHashNode, to be only created on the stack

ConstHashIterator hi(h);
while (hi.next()) {
QoreStringValueHelper str(hi.getValue());
printf("key: '%s', value: '%s'\n", hi.getKey(), str->getBuffer());
}

Member Function Documentation

DLLEXPORT bool ConstHashIterator::next ( )

moves to the next element, 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)

DLLEXPORT bool ConstHashIterator::prev ( )

moves to the previous element, 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)

The documentation for this class was generated from the following file:
