Class SerializableXid

java.lang.Object

org.infinispan.transaction.xa.recovery.SerializableXid

All Implemented Interfaces:

Xid

@Immutable
public class SerializableXid
extends Object
implements Xid

This xid implementation is needed because Xid is not Serializable and we need to serialize it and send it over the network. As the KTA spec does not enforce in anyway the equals and hashcode methods on Xid TM providers are expected to be able to cope with this Xid class when returned from XAResource's methods.

Since:

5.0

Method Detail

getBranchQualifier

public byte[] getBranchQualifier()

Description copied from interface: Xid

Get the transaction branch qualifier of this transaction. Please note that JTA does not define if this method returns a copy or a reference to an internal byte array. For maximum portability, do not modify the returned array.

Specified by:

getBranchQualifier in interface Xid

Returns:

A byte array that identifies the branch of this transaction.

getGlobalTransactionId

public byte[] getGlobalTransactionId()

Description copied from interface: Xid

Get the global transaction id of this transaction. Please note that JTA does not define if this method returns a copy or a reference to an internal byte array. For maximum portability, do not modify the returned array.

Specified by:

getGlobalTransactionId in interface Xid

Returns:

A byte array that together with the format ID defines the globally unique ID of this transaction.

getFormatId

public int getFormatId()

Description copied from interface: Xid

Get the format identifier.

Specified by:

getFormatId in interface Xid

Returns:

An integer denoting the family of this transaction, and telling how the two other parts can be interpreted.

equals

public boolean equals(Object o)

Overrides:

equals in class Object
