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

Class TxnBatchedPositionImpl

java.lang.Object
org.apache.bookkeeper.mledger.impl.PositionImpl
org.apache.pulsar.transaction.coordinator.impl.TxnBatchedPositionImpl
All Implemented Interfaces:
Comparable<org.apache.bookkeeper.mledger.impl.PositionImpl>, org.apache.bookkeeper.mledger.Position
public class TxnBatchedPositionImpl extends org.apache.bookkeeper.mledger.impl.PositionImpl
The difference with PositionImpl is that there are two more parameters: batchSize, batchIndex.

    Method
    Description
    int
    compareTo(org.apache.bookkeeper.mledger.impl.PositionImpl that)
    It's exactly the same as PositionImpl，to make sure that when compare to the "markDeletePosition", it looks like PositionImpl.
    boolean
    equals(Object o)
    It's exactly the same as PositionImpl，make sure that when TxnBatchedPositionImpl used as the key of map same as PositionImpl.
    int

    It's exactly the same as PositionImpl，make sure that when TxnBatchedPositionImpl used as the key of map same as PositionImpl.
    void
    setAckSetByIndex()
    Build the attribute ackSet to that batchIndex is false and others is true.

    • equals

      public boolean equals(Object o)
      It's exactly the same as PositionImpl，make sure that when TxnBatchedPositionImpl used as the key of map same as PositionImpl. batchSize and batchIndex should not be involved in calculate, just like PositionImpl.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 org.apache.bookkeeper.mledger.impl.PositionImpl

    • hashCode

      public int hashCode()
      It's exactly the same as PositionImpl，make sure that when TxnBatchedPositionImpl used as the key of map same as PositionImpl. batchSize and batchIndex should not be involved in calculate, just like PositionImpl.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 org.apache.bookkeeper.mledger.impl.PositionImpl

    • compareTo

      public int compareTo(org.apache.bookkeeper.mledger.impl.PositionImpl that)
      It's exactly the same as PositionImpl，to make sure that when compare to the "markDeletePosition", it looks like PositionImpl. batchSize and batchIndex should not be involved in calculate, just like PositionImpl.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.
