Class GlobalXact

java.lang.Object

org.apache.derby.iapi.store.access.GlobalXact

Direct Known Subclasses:

GlobalXactId, XAXactId

public abstract class GlobalXact
extends java.lang.Object

This abstract class represents a global transaction id which can be tested for equality against other transaction ids, which can be hashed into a hash table, and which can be output as a string.

This class has 2 direct subclasses.

• org.apache.derby.iapi.store.access.xa.XAXactId : this class is a specific implementation of the JTA Xid interface
• org.apache.derby.impl.store.access.GlobalXactId : this class represents internal Derby transaction ids

The main reason for this class is to ensure that equality etc. works in a consistent way across both subclasses.
