Class: TCommandRequiringDataFixup

Declaration: CompoundDocumentCommand.h

Taxonomy Categories:

Member Functions:

Interface Category:

API.

Inherits From:

TCommandOn, MCommandRequiringDataFixup

Inherited By:

TAbsorbDataCommand TReplaceDataCommand

Purpose:

This command is a base class for commands that use model data that must be fixed up prior to passing the data to a target selection. The Document Frameworks guarantee that model's are fixed up prior to logging of the command for recovery, so that an IDs assigned as part of fixup are deterministic if the log is replayed.

Instantiation:

Allocate on the heap or the stack.

Deriving Classes:

Derive commands from this class that require fixup to be performed on a TModel before Do.

Concurrency:

Not multithread safe.

Resource Use:

No special requirements.

Invariants:

Assert (GetModel() != NIL)
