Detailed Description

FCompoundChange applies a sequence of FSwapChanges. The changes are executed in reverse order (this is like a mini undo stack)

Constructor & Destructor Documentation

◆ FCompoundChange()

FCompoundChange::FCompoundChange ( FCompoundChangeInput &&  InitInput)

Constructor

Member Function Documentation

◆ Execute()

TUniquePtr< FChange > FCompoundChange::Execute ( UObject *  Object)
overridevirtual

Makes the change to the object, returning a new change that can be used to perfectly roll back this change

Implements FChange.

◆ PrintToLog()

void FCompoundChange::PrintToLog ( class FFeedbackContext &  FeedbackContext,
const int32  IndentLevel = 0 
)
overridevirtual

Prints this change to the log, including sub-changes if there are any. For compound changes, there might be multiple lines. You should not need to override this function.

Reimplemented from FChange.

◆ ToString()

FString FCompoundChange::ToString ( ) const
overridevirtual

Describes this change (for debugging)

Implements FChange.
