|
| addDmiDescriptor | | public void addDmiDescriptor(DmiDescriptor d)(Code) | | Add distributed method call descriptor to current transaction
Parameters:
d - Descriptor |
| addReference | | public void addReference(TCObject tco)(Code) | | Add reference to tco in current transaction
Parameters:
tco - TCObject |
| apply | | public void apply(TxnType txType, List lockIDs, Collection objectChanges, Set lookupObjectIDs, Map newRoots)(Code) | | When transactions come in from the L2 we use this method to apply them. We will have to get a bit fancier because
we can't apply any changes while we are in any transaction. The first version will not allow apply to happen while
ANY tx is in progress. This is probably not exceptable. We will probably figure something out with the lock manager
where we can accuire a read lock if a field is accessed in a transaction
Parameters:
txType - Transaction type
Parameters:
lockIDs - Locks involved in the transaction
Parameters:
objectChanges - Collection of DNA indicating changes
Parameters:
lookupObjectIDs - ObjectIDs
Parameters:
newRoots - Map of new roots, Root name -> ObjectID |
| arrayChanged | | public void arrayChanged(TCObject src, int startPos, Object array, int length)(Code) | | Record an array change in the current transaction
Parameters:
src - The TCObject for the array
Parameters:

Parameters:
array - The new partial array or value

Parameters:
lock - Lock name
Parameters:
lockLevel - Lock level If begun |
| createObject | | public void createObject(TCObject source)(Code) | | Add new managed object to current transaction
Parameters:

| createRoot | | public void createRoot(String name, ObjectID id)(Code) | | Add new root to current transaction
Parameters:
name - Root name
Parameters:
id - Object identifier |
