◆ Changed()

bool AzToolsFramework::EntityStateCommand::Changed ( ) const

inlineoverridevirtual

Usage: override with class specific change comparison between undo/redo state. This allows the undo system to remove commands that have no actual effect (Eg: a command that changes a value from 5 to 5 has no effect and can be removed)
