Class RdosFileEntry

  • All Implemented Interfaces:
    FileEntry
    public class RdosFileEntry
extends java.lang.Object
implements FileEntry
    Handle RDOS file entry format.

    Since I was unable to locate the file entries on the internet, it is documented here: Offset Description
    ====== ====================================================
    $00-$17 File name; space-filled. If the first byte is $00, that is the end of the
    directory. If the first byte is $80, the file is deleted.
    $18 File type. Appears to be actual letter ('A'=Applesoft, etc)
    $19 File length in blocks (block = sector = 256 bytes)
    $1A-$1B Address of application. For Applesoft and binary; others may vary.
    $1C-$1D Length in bytes of file.
    $1E-$1F Starting block of application.

        getFileData in interface FileEntry

      • getSuggestedFilter

        public FileFilter getSuggestedFilter()
        Get the suggested FileFilter. This appears to be operating system specific, so each operating system needs to implement some manner of guessing the appropriate filter. FIXME - this code should be a helper class for DOS and RDOS!
        Specified by:
        getSuggestedFilter in interface FileEntry

      • isTextFile

        public boolean isTextFile()

        getFormattedDisk 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.

        needsAddress in interface FileEntry

      • setAddress

        public void setAddress​(int address)
        Set the address that this file loads at.
        Specified by:
