      getFileData in interface FileEntry

    • setFileData

      public void setFileData(byte[] data) throws DiskFullException
      Set the file data. This is essentially the save operation. Specifically, if the filetype is binary, the length and address need to be set. If the filetype is applesoft or integer basic, the start address needs to be set.
      Specified by:
      setFileData in interface FileEntry
      Throws:

      Throws:
      DiskFullException

    • getSuggestedFilter

      public FileFilter getSuggestedFilter()

      Specified by:
      getSuggestedFilter in interface FileEntry

    • needsAddress

      public boolean needsAddress()
      Indicates if this filetype requires an address component. Note that the FormattedDisk also has this method - normally, this will defer to the method on FormattedDisk, as it will be more generic.
      Specified by:
      needsAddress in interface FileEntry

    • setAddress

      public void setAddress(int address)
      Set the address that this file loads at.

      setAddress in interface FileEntry

    • getAddress
