        byte[] branchid)

Method Detail

getFormatId

public int getFormatId()

Obtain the format id part of the Xid.

Specified by:

getFormatId in interface javax.transaction.xa.Xid

---

getGlobalTransactionId

public byte[] getGlobalTransactionId()

Obtain the global transaction identifier part of XID as an array of bytes.

Specified by:

getGlobalTransactionId in interface javax.transaction.xa.Xid

---

getBranchQualifier

public byte[] getBranchQualifier()

Obtain the transaction branch qualifier part of the Xid in a byte array.

Specified by:

getBranchQualifier in interface javax.transaction.xa.Xid

---

toString

public java.lang.String toString()

Description copied from class: java.lang.Object

Convert this Object to a human-readable String. There are no limits placed on how long this String should be or what it should contain. We suggest you make it as intuitive as possible to be able to place it into System.out.println() 55 and such.

It is typical, but not required, to ensure that this method never completes abruptly with a java.lang.RuntimeException.

This method will be called when performing string concatenation with this object. If the result is null, string concatenation will instead use "null".

The default implementation returns getClass().getName() + "@" + Integer.toHexString(hashCode()).

---

convertToHexString

private static java.lang.String convertToHexString(byte[] buf)

convert byte array to a Hex string
