List of modifications (Modification)
List of nodes that were created as part of lock acquisition. These nodes can be safely deleted when a transaction is rolled back
List of locks (IdentityLock (src) ) that have been acquired by this transaction so far

Field Detail

ltx

protected Transaction (src)  ltx

Local transaction

modification_list

protected java.util.List modification_list

List of modifications (MethodCall). They will be replicated on TX commit

undo_list

protected java.util.List undo_list

List. List of compensating org.jgroups.blocks.MethodCall objects which revert the ones in modification_list. For each entry in the modification list, we have a corresponding entry in this list. A rollback will simply iterate over this list in reverse to undo the modifications. Note that these undo-ops will never be replicated.

nodes

protected java.util.List nodes

List of nodes created. Elements are fully qualified names (Fqns)

locks

protected java.util.List locks

List of locks acquired by the transaction (IdentityLock (src) )
