Constructor Detail

OracleXid

public OracleXid(int fId,
                 byte[] gId,
                 byte[] bId)
          throws javax.transaction.xa.XAException

OracleXid() -- The constructor that constructs an OracleXid with given formatId, global transacrion Id and branch qualifier.

Parameters:

fId - format ID

gId - global transaction ID (no copy performed)

bId - branch Qualifier (no copy performed)

Throws:

javax.transaction.xa.XAException - if the size of gId or bId is more than 64 bytes

OracleXid

public OracleXid(int fId,
                 byte[] gId,
                 byte[] bId,
                 byte[] context)
          throws javax.transaction.xa.XAException

OracleXid() -- The constructor that constructs an OracleXid with given formatId, global transacrion Id and branch qualifier, and transaction context.

Parameters:

fId - format ID

gId - global transaction ID (no copy performed)

bId - branch Qualifier (no copy performed)

context - transation context (no copy performed)

Throws:

javax.transaction.xa.XAException - if the size of gId or bId is more than 64 bytes

Specified by:

getFormatId in interface javax.transaction.xa.Xid

Returns:

Format identifier. 0 means the OSI CCR format.

getGlobalTransactionId

public byte[] getGlobalTransactionId()

getGlobalTransactionId() -- Obtain the global txn id of the XID

Specified by:

getGlobalTransactionId in interface javax.transaction.xa.Xid

Returns:

A byte array containing the global transaction identifier.

getBranchQualifier

public byte[] getBranchQualifier()

getBranchQualifier() -- Obtain the txn branch qualifier of the XID

Specified by:

getBranchQualifier in interface javax.transaction.xa.Xid

Returns:

A byte array containing the branch qualifier of the transaction.

isLocalTransaction

public static final boolean isLocalTransaction(javax.transaction.xa.Xid xid)
