Method Detail

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.

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.

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.
