Constructor Detail

XID

public XID(String tid,
   String resourceURL)

Create a new instance with the resource name as branch. This is the main constructor for new instances.

Parameters:

tid - The global transaction identifier.

resourceURL - The name of the resource in the current configuration (UNIQUE!), needed for recovering the XIDs for this configuration. The resulting branch qualifier will ALWAYS start with the name of the resource, and this can be used during recovery to identify the XIDs to be recovered.

XID

public XID(Xid xid)

Copy constructor needed during recovery: if the data source returns inappropriate instances (that do not implement equals and hashCode) then we will need this constructor.

Parameters:

xid - The xid.
