Description

Interface Summary
Adaptable: Interface implemented by transactional editing domains that support dynamic adaptation to optional interfaces.
ConditionalRedoCommand: A specialization of the EMF `Command` API that accounts for conditional redoable-ness.
ValidateEditSupport: Interface for the `Transaction.OPTION_VALIDATE_EDIT` transaction option to check, when a transaction commits, that all of the resources that it has modified are actually editable or (by some means supplied by the platform) can be made to be editable.

Class Summary
CommandChangeDescription: A change description that simply wraps a `Command`, asking it to undo or redo when `applying`.
CompositeChangeDescription: A composition of zero or more change descriptions representing the changes performed by transactions in a possibly nested structure.
ConditionalRedoCommand.Compound: A conditionally redoable compound command.
Lock: Implementation of a lock.
TransactionUtil: Static utilities for dealing with EMF elements and resources in a transactional editing domain.
TriggerCommand: A specialized compound command that combines a "triggering" command with commands contributed by `ResourceSetListener`s as triggers.
ValidateEditSupport.Default: A default implementation of the `ValidateEditSupport` interface, that uses the editing domain's read-only resource map to determine whether a resource can be edited and depends on notifications of the `Resource.isModified()` property changing to track which resources need to be validated (note that this implies that the resource is tracking modifications).
