Module Summary
Description
To get access to the record definitions for the structures use:
-include_lib("cosTransactions/include/CosTransactions.hrl").
Exports
create_subtransaction(Coordinator) -> Control
Types
A new subtransaction is created whose parent is the Coordinator argument.
Raises exception:
- 'SubtransactionsUnavailable' - if nested transactions are not supported.

get_transaction_name(Coordinator) -> Name
Types
Returns a printable string, which describe the transaction. The main purpose is to support debugging.
get_parent_status(Coordinator) -> Status
Types
Returns the status of the parent transaction associated with the target object. If the target object is a top-level transaction this operation is equivalent to get_status/1 operation.
Possible Status replies:
- 'StatusCommitted'
- 'StatusCommitting'
- 'StatusMarkedRollback'
- 'StatusRollingBack'
- 'StatusRolledBack'
- 'StatusActive'
- 'StatusPrepared'
- 'StatusUnknown'
- 'StatusNoTransaction'
- 'StatusPreparing'
get_status(Coordinator) -> Status
Types
Returns the status of the transaction associated with the target object.
get_top_level_status(Coordinator) -> Status
Types
Returns the status of the top-level transaction associated with the target object.
hash_top_level_tran(Coordinator) -> Return
Types
Returns a hash code for the top-level transaction associated with the target object. Equals the operation hash_transaction/1 if the target object is a top-level transaction.
hash_transaction(Coordinator) -> Return
Types
Returns a hash code for the transaction associated with the target object.
is_descendant_transaction(Coordinator, OtherCoordinator) -> Return
Types
Returns true if the transaction associated with the target object is a descendant of the transaction associated with the parameter object.
is_same_transaction(Coordinator, OtherCoordinator) -> Return
Types
Returns true if the transaction associated with the target object is related to the transaction associated with the parameter object.
is_top_level_transaction(Coordinator) -> Return
Types
Returns true if the transaction associated with the target object is a top-level transaction.
register_resource(Coordinator, Resource) -> RecoveryCoordinator
Types
This operation registers the parameter Resource object as a participant in the transaction associated with the target object. The RecoveryCoordinator returned by this operation can be used by this Resource during recovery.
The Resources will be called in FIFO-order when preparing or committing. Hence, be sure to register the Resources in the correct order.
Raises exception:
- 'Inactive' - if target transaction has already been prepared.
register_subtran_aware(Coordinator, SubtransactionAwareResource) -> Return
Types
This operation registers the parameter SubtransactionAwareResource object such that it will be notified when the transaction, associated wit the target object, has committed or rolled back.
