函数SplitNodeGuttman用于分裂结点
static int splitNodeGuttman(
Rtree *pRtree,
RtreeCell *aCell,
int nCell,
RtreeNode *pLeft,
RtreeNode *pRight,
RtreeCell *pBboxLeft,
RtreeCell *pBboxRight
)
函数LinearPickSeeds用于为分裂后的左右结点选择第一条记录
static void LinearPickSeeds(
Rtree *pRtree,
RtreeCell *aCell,
int nCell,
int *piLeftSeed,
int *piRightSeed
)
函数LinearPickNext用于为分裂后的左右结点选择下一条插入记录
static RtreeCell *LinearPickNext(
Rtree *pRtree,
RtreeCell *aCell,
int nCell,
RtreeCell *pLeftBox,
RtreeCell *pRightBox,
int *aiUsed
)
