Method Detail

compare

protected int compare(BPlusIO<CacheSearchRow> io,
          long pageAddr,
          int idx,
          CacheSearchRow row)
               throws IgniteCheckedException

Specified by:

compare in class BPlusTree<CacheSearchRow,CacheDataRow>

Parameters:

io - IO.

pageAddr - Page address.

idx - Index of row in the given buffer.

row - Lookup row.

Returns:

Comparison result as in Comparator.compare(Object, Object).

Throws:

IgniteCheckedException - If failed.

getRow

protected CacheDataRow getRow(BPlusIO<CacheSearchRow> io,
                  long pageAddr,
                  int idx,
                  Object flags)
                       throws IgniteCheckedException

Get data row. Can be called on inner page only if BPlusTree.canGetRowFromInner is true.

Specified by:

getRow in class BPlusTree<CacheSearchRow,CacheDataRow>

Parameters:

io - IO.

pageAddr - Page address.

idx - Index.

flags - Implementation specific argument, null always means that we need to return full detached data row.

Returns:

Data row.

Throws:

IgniteCheckedException - If failed.
