Method Detail

openFile

public static void openFile(java.io.PrintStream outAndErrStream,
                            TurtleField oldTurtleField)

Opens a file that contains either a serialized LinkedList or a .logo file

Parameters:

outAndErrStream - The stream for notifications

loadLogoFile

public static void loadLogoFile(java.lang.String fileName,
                                java.io.PrintStream outAndErrStream,
                                java.io.BufferedReader subroutine)
                         throws java.io.IOException

Loads a .logo file as a new workspace

Parameters:

fileName - The name of the file so that it can be saved to later

outAndErrStream - The stream for notifications

subroutine - The reader containing the instructions

Throws:

java.io.IOException - In case there's a bad file

loadSerFile

public static void loadSerFile(java.lang.String fileName,
                               java.util.LinkedList<java.lang.String> instructionHistory,
                               java.io.PrintStream outAndErrStream,
                               java.lang.String parentDirectory,
                               TurtleField oldTurtleField)

Loads the file by executing all the commands from the linked list and defining instance variables Checks the directory to see if it needs to open a new workspace or just modify the current one Checks to see if the .ser file is an assignment history Also checks to see if there is an image file associated with the saved workspace

Parameters:

fileName - The name of the file

instructionHistory - The history from the file

outAndErrStream - The stream for notifications

turtleField - The original turtle field in case the user loads assignments
