| long | getFreqPointer()Returns the freq pointer of the doc to which the last call of
{@link MultiLevelSkipListReader#skipTo(int)} has skipped.
return lastFreqPointer;
|
| int | getPayloadLength()Returns the payload length of the payload stored just before
the doc to which the last call of {@link MultiLevelSkipListReader#skipTo(int)}
has skipped.
return lastPayloadLength;
|
| long | getProxPointer()Returns the prox pointer of the doc to which the last call of
{@link MultiLevelSkipListReader#skipTo(int)} has skipped.
return lastProxPointer;
