Class InvalidTxList

java.lang.Object

org.apache.tephra.manager.InvalidTxList

@NotThreadSafe
public class InvalidTxList
extends Object

This is an internal class used by the TransactionManager to store invalid transaction ids. This class uses both a list and an array to keep track of the invalid ids. The list is the primary data structure for storing the invalid ids. The array is populated lazily on changes to the list. The array is used to avoid creating a new array every time method toSortedArray() is invoked. This class is not thread safe and relies on external synchronization. TransactionManager always accesses an instance of this class after synchronization.
