The CanGoBack method of the Editor.HistoryStack<T> class checks if there is a previous state available in the history stack that can be navigated back to. This method is useful for determining whether a "back" operation is possible, such as in undo functionality.
Call the CanGoBack method to check if the history stack has a previous state that can be navigated to. This method returns a boolean value indicating the availability of a previous state.
// Example usage of CanGoBack method
Editor.HistoryStack<string> historyStack = new Editor.HistoryStack<string>();
// Add some states to the history stack
historyStack.Add("State1");
historyStack.Add("State2");
// Check if we can go back
bool canGoBack = historyStack.CanGoBack();
if (canGoBack)
{
// Perform the go back operation
string previousState = historyStack.GoBack();
// Now previousState contains "State1"
}
