Interface Xid

public interfaceXid

The Xid interface is a Java mapping of the X/Open transaction identifier XID structure. This interface specifies three accessor methods to retrieve a global transactions format ID, global transaction ID, and branch qualifier. The Xid interface is used by the transaction manager and the resource managers. This interface is not visible to the application programs.


	`MAXBQUALSIZE` Maximum number of bytes returned by getBqual.
	`MAXGTRIDSIZE` Maximum number of bytes returned by getGtrid.


	`getBranchQualifier()` Obtain the transaction branch identifier part of XID as an array of bytes.
	`getFormatId()` Obtain the format identifier part of the XID.
	`getGlobalTransactionId()` Obtain the global transaction identifier part of XID as an array of bytes.

MAXGTRIDSIZE

public static final intMAXGTRIDSIZE

Maximum number of bytes returned by getGtrid.

MAXBQUALSIZE

public static final intMAXBQUALSIZE

Maximum number of bytes returned by getBqual.

getFormatId

public intgetFormatId()

Obtain the format identifier part of the XID.

Returns:: Format identifier. O means the OSI CCR format.

getGlobalTransactionId

public byte[]getGlobalTransactionId()

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

Returns:: Global transaction identifier.

getBranchQualifier

public byte[]getBranchQualifier()

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

Returns:: Global transaction identifier.
