BeginTransaction()

int BeginTransaction	(	FString	Context,
		FText	Description,
		UObject	PrimaryObject )

Begin a new undo transaction. An undo transaction is defined as all actions which take place when the user selects "undo" a single time. Note: If there is already an active transaction in progress, then this increments that transaction's action counter instead of beginning a new transaction. Note: You must call TransactObject before modifying each object that should be included in this undo transaction. Note: Only available in the editor.

Parameters

Context	The context for the undo session. Typically the tool/editor that caused the undo operation.
Description	The description for the undo session. This is the text that will appear in the "Edit" menu next to the Undo item.
PrimaryObject	The primary object that the undo session operators on (can be null, and mostly is).

Returns

The number of active actions when BeginTransaction was called (values greater than 0 indicate that there was already an existing undo transaction in progress), or -1 on failure.
