Constructor Detail

XidImpl

public XidImpl()

Create a new instance.

XidImpl

public XidImpl(XidImpl xid,
               int branchId)

Create a new branch of an existing global transaction ID.

Parameters:

xid - The transaction ID to create a new branch of.

branchId - The ID of the new branch.

Method Detail

getGlobalTransactionId

public byte[] getGlobalTransactionId()

Return the global transaction id of this transaction.

Specified by:

getGlobalTransactionId in interface javax.transaction.xa.Xid

getBranchQualifier

public byte[] getBranchQualifier()

Return the branch qualifier of this transaction.

Specified by:

getBranchQualifier in interface javax.transaction.xa.Xid

getFormatId

public int getFormatId()

Return the format identifier of this transaction. The format identifier augments the global id and specifies how the global id and branch qualifier should be interpreted.

Specified by:

getFormatId in interface javax.transaction.xa.Xid

equals

public boolean equals(java.lang.Object obj)

Compare for equality. Instances are considered equal if they are both instances of XidImpl, and if they have the same global transaction id and transaction branch qualifier.

Overrides:

equals in class java.lang.Object

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

toString

public java.lang.String toString()
