Constructor Detail

### AbstractDumpFormat

    public AbstractDumpFormat(String name,
                              String commandDescriptor,
                              String description,
                              String extension)

  Typical constructor. Note you cannot creates objects from this class but subclass constructor can call this one.

  Parameters:
    `name` - Brief descriptive name to be displayed in selection list.
    `commandDescriptor` - One-word descriptive name to be used by MARS command mode parser and user. Any spaces in this string will be removed.
    `description` - Description to go with standard file extension for display in file save dialog or to be used as tool tip.
    `extension` - Standard file extension for this format. Null if none.

Method Detail

### getFileExtension

    public String getFileExtension()

  Get the file extension associated with this format.

  Specified by:
    `getFileExtension` in interface `DumpFormat`
  Returns:
    String containing file extension -- without the leading "." -- or null if there is no standard extension.

### getDescription

    public String getDescription()

  Get a short description of the format, suitable for displaying along with the extension, in the file save dialog, or as a tool tip.

  Specified by:
    `getDescription` in interface `DumpFormat`
  Returns:
    String containing short description to go with the extension or for use as tool tip. Possibly null.

### toString

    public String toString()

  String representing this object.

  Specified by:
    `toString` in interface `DumpFormat`
  Overrides:
    `toString` in class `Object`
  Returns:
    Name given for this object.

### getCommandDescriptor

    public String getCommandDescriptor()

  One-word description of format to be used by MARS command mode parser and user in conjunction with the "dump" option.

  Specified by:
    `getCommandDescriptor` in interface `DumpFormat`
  Returns:
    One-word String describing the format.

### dumpMemoryRange

    public abstract void dumpMemoryRange(File file,
                                         int firstAddress,
                                         int lastAddress)
                                  throws AddressErrorException,
                                         IOException

  Write MIPS memory contents according to the specification for this format.

  Specified by:
    `dumpMemoryRange` in interface `DumpFormat`
  Parameters:
    `file` - File in which to store MIPS memory contents.
    `firstAddress` - first (lowest) memory address to dump. In bytes but must be on word boundary.
    `lastAddress` - last (highest) memory address to dump. In bytes but must be on word boundary. Will dump the word that starts at this address.
