Package org.apache.pulsar.transaction.coordinator.impl

Class TxnBatchedPositionImpl

java.lang.Object

org.apache.bookkeeper.mledger.impl.AckSetPositionImpl

org.apache.pulsar.transaction.coordinator.impl.TxnBatchedPositionImpl

All Implemented Interfaces:

Comparable<Position>, AckSetState, Position

public class TxnBatchedPositionImpl
extends AckSetPositionImpl

The difference with AckSetPositionImpl is that there are two more parameters: batchSize, batchIndex.

Modifier and Type	Method	Description
int	compareTo(Position that)	It's exactly the same as Position，to make sure that when compare to the "markDeletePosition", it looks like Position.
boolean	equals(Object o)	It's exactly the same as Position，make sure that when TxnBatchedPositionImpl used as the key of map same as Position.
int	hashCode()	It's exactly the same as Position，make sure that when TxnBatchedPositionImpl used as the key of map same as Position.
void	setAckSetByIndex()	Build the attribute ackSet to that batchIndex is false and others is true.

Constructor Details

TxnBatchedPositionImpl

public TxnBatchedPositionImpl(long ledgerId,
 long entryId,
 int batchSize,
 int batchIndex)

TxnBatchedPositionImpl

public TxnBatchedPositionImpl(Position position,
 int batchSize,
 int batchIndex)

Method Details

equals

public boolean equals(Object o)

It's exactly the same as Position，make sure that when TxnBatchedPositionImpl used as the key of map same as Position. batchSize and batchIndex should not be involved in calculate, just like the included AckSetPositionImpl.ackSet is not involved in calculate. Note: In ConcurrentSkipListMap, it use the Comparable.compareTo(Object) to determine whether the keys are the same. In HashMap, it use the Object.hashCode() & Object.equals(Object) to determine whether the keys are the same.

Overrides:

equals in class AckSetPositionImpl

hashCode

public int hashCode()

It's exactly the same as Position，make sure that when TxnBatchedPositionImpl used as the key of map same as Position. batchSize and batchIndex should not be involved in calculate, just like the included AckSetPositionImpl.ackSet is not involved in calculate. Note: In ConcurrentSkipListMap, it use the Comparable.compareTo(Object) to determine whether the keys are the same. In HashMap, it use the Object.hashCode() & Object.equals(Object) to determine whether the keys are the same.

Overrides:

hashCode in class AckSetPositionImpl

compareTo

public int compareTo(Position that)

It's exactly the same as Position，to make sure that when compare to the "markDeletePosition", it looks like Position. batchSize and batchIndex should not be involved in calculate, just like the included AckSetPositionImpl.ackSet is not involved in calculate. Note: In ConcurrentSkipListMap, it use the Comparable.compareTo(Object) to determine whether the keys are the same. In HashMap, it use the Object.hashCode() & Object.equals(Object) to determine whether the keys are the same.

setAckSetByIndex

public void setAckSetByIndex()

Build the attribute ackSet to that batchIndex is false and others is true.
