示例1: begin
BPlusTreeIterator* BPlusTree::begin() {
BPlusTreeIterator* iterator = NULL;
LeafNode* leaf = static_cast <LeafNode*> (hidratateNode(firstLeaf));
if (leaf) {
iterator = new BPlusTreeIterator(leaf->clone(), 0, fileBlockManager);
freeNodeMemory(leaf);
}
return iterator;
}示例2: getPosition
pair<Record*, BPlusTreeIterator*> BPlusTree::search(Key k) {
Node *aNode = root;
if (!aNode)
return pair<Record*, BPlusTreeIterator*> (NULL, NULL);
while (!aNode->isLeaf()) {
InnerNode *innerNode = static_cast<InnerNode*> (aNode);
int position = getPosition(innerNode, k);
aNode = hidratateNode(innerNode->sons[position]);
if (innerNode != root)
freeNodeMemory(innerNode);
}
LeafNode *leafNode = static_cast<LeafNode*> (aNode);
Record* record = NULL;
BPlusTreeIterator* iterator = NULL;
int pos = getPosition(leafNode, k);
if (pos < leafNode->keyMount && equalKey(k, leafNode->keys[pos])) {
