Client concepts for dealing with transactions, distributed transactions and their save points.

Interface Summary
Interface	Description
CDOCommitContext	Provides a context for commit operations.
CDOConflictResolver	A strategy used to customize the default conflict resolution behavior of `transactions`.
CDOConflictResolver.NonConflictAware	A mix-in interface for `conflict resolvers` that need to know about non-conflicting invalidations.
CDOConflictResolver2	A strategy used to customize the default conflict resolution behavior of `transactions`.
CDOConflictResolver3	A strategy used to customize the default conflict resolution behavior of `transactions`.
CDOMerger	Calculates the changes between a source `change set` and a target `change set` and returns the result relative to their common ancestor.
CDOMerger2	Merges the changes between a local `transaction` and a remote `view` into the local transaction.
CDOSavepoint	One in a sequence of possibly several points in time of a `transaction` that encapsulates the changes to transactional objects and that later changes can be `rolled back` to.
CDOStaleReferenceCleaner	Interface to externalize the cleaning of stale references created on invalidation.
CDOTransaction	A read-write view to the current (i.e.
CDOTransaction.Options	Encapsulates a set of notifying `transaction` configuration options.
CDOTransaction.Options.AttachedRevisionsMap	An `options event` fired from transaction `options` when the `attached revisions map` option has changed.
CDOTransaction.Options.AutoReleaseLocksEvent	An `options event` fired from transaction `options` when the `auto release locks enabled` or `auto release locks exemptions` options have changed.
CDOTransaction.Options.AutoReleaseLocksEvent.AutoReleaseLocksEnabledEvent	An `auto release locks options event` fired from transaction `options` when the `auto release locks enabled` option has changed.
CDOTransaction.Options.AutoReleaseLocksEvent.AutoReleaseLocksExemptionsEvent	An `auto release locks options event` fired from transaction `options` when the `auto release locks exemptions` option has changed.
CDOTransaction.Options.CommitInfoTimeout	An `options event` fired from transaction `options` when the `commit info timeout` option has changed.
CDOTransaction.Options.ConflictResolversEvent	An `options event` fired from transaction `options` when the `conflict resolvers` option has changed.
CDOTransaction.Options.StaleReferenceCleanerEvent	An `options event` fired from transaction `options` when the `stale reference cleaner` option has changed.
CDOTransaction.Options.UndoDetectorEvent	An `options event` fired from transaction `options` when the `undo detector` option has changed.
CDOTransactionConflictEvent	A `view event` fired from a `transaction` for each `object` that enters the `conflict` state.
CDOTransactionContainer	Can open new `transactions` and provide access to openend transactions.
CDOTransactionFinishedEvent	A `view event` fired from a `transaction` when it becomes `clean` after a sucessful `commit` or `rollback`.
CDOTransactionHandler	A combination of `CDOTransactionHandler1` and `CDOTransactionHandler2`.
CDOTransactionHandler1	A call-back interface that is called by a `transaction` before `objects` are attached, modified or detached.
CDOTransactionHandler1.WithUndo	A call-back interface that is called by a `transaction` before `objects` are attached, modified, undone or detached.
CDOTransactionHandler2	A call-back interface that is called by a `transcation` before it is committed and after it has been committed or rolled back.
CDOTransactionHandler3	A call-back interface that is called by a `transcation` before it is committed and after it has been committed (with result info) or rolled back.
CDOTransactionHandlerBase	A marker interface for use with `CDOTransaction.addTransactionHandler()` and `CDOTransaction.removeTransactionHandler()`.
CDOTransactionOpener	Can open new `transactions`.
CDOTransactionStartedEvent	A `view event` fired from a `transaction` when it first becomes `dirty`.
CDOUndoDetector	A strategy used to detect whether the feature of an `object` has the original (clean) value after a number of modifications.
CDOUserSavepoint	Creates a save point in a `CDOUserTransaction` that can be used to roll back a part of the transaction.
CDOUserTransaction	Provides functionality that is common to both `single` transactions and `distributed` (XA) transactions.
CDOXASavepoint	Creates a save point in a `CDOXATransaction` that can be used to roll back a part of the transaction.
CDOXATransaction	A distributed (XA) transaction that can atomically commit the changes to multiple `resource sets`, each represented by a registered `view set`.

Class Summary
Class	Description
CDOAsyncTransactionHandler	Asynchronously executes a delegate handler's pre-event methods.
CDOAutoAttacher	A `transaction handler` that automatically attaches cross-referenced objects to the `resource` that contains the referencing `object`.
CDOAutoCommitter	A `transaction handler` that automatically `commits` the `transaction` after an `object` was modified.
CDOAutoLocker	A `transaction handler` that automatically acquires `write locks` when `objects` are modified.
CDOAutoLocker.ForSingleValuedChanges	An `auto locker` that only locks objects when their single-valued features are changed.
CDODefaultTransactionHandler	An empty default implementation of `CDOTransactionHandler1` and `CDOTransactionHandler2`.
CDODefaultTransactionHandler1	An empty default implementation of `CDOTransactionHandler1`.
CDODefaultTransactionHandler2	An empty default implementation of `CDOTransactionHandler2`.
CDODefaultTransactionHandler3	An empty default implementation of `CDOTransactionHandler3`.
CDOPostEventTransactionHandler	An abstract call-back class that is called by a `transcation` after `objects` have been attached, modified or detached.
CDOPostEventTransactionHandler.Default	An empty default implementation of `CDOPostEventTransactionHandler`.
CDOPushTransaction	A `transaction` that persists changes to the object graph locally on commit and can later load these changes and push them to the `repository`.
CDOStaleReferenceCleaner.Default	A default `CDOStaleReferenceCleaner` that can be used on invalidation.
CDOTransaction.CommitResult<T>	A value type that combines the result of a persistable computation and the `commit info` of the final `transaction commit`.
CDOTransactionCommentator	A utility class that, when associated with a `transaction`, automatically updates the `commit comment` according to local model modifications.

Enum Summary
Enum	Description
CDOTransactionFinishedEvent.Cause	Enumerates the possible `causes` for a `transaction` to become finished.
CDOTransactionFinishedEvent.Type	Deprecated. As of 4.3 use `CDOTransactionFinishedEvent.Cause`.
