      • isDeleted

        public boolean isDeleted()
        Pascal file entries are removed upon deletion, so a file entry need not be marked as deleted. But the GUI still has a copy of the file list in memory, so we mark it deleted in delete().
        Specified by:
        isDeleted in interface FileEntry

      • delete

        Delete the file.

        getFileColumnData in interface FileEntry

      • getFileData

        public byte[] getFileData()
        Get file data. This handles any operating-system specific issues. Currently, the disk itself handles this.

        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.

        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.
        Specified by:
        setAddress in interface FileEntry

        public boolean canCompile()
        Indicates that this filetype can be compiled.

        canCompile in interface FileEntry

      • setEntryIndex

        public void setEntryIndex​(int index)
        Remember the index of a newly created file entry. Required to update the entry after setFileData, which may change any or all of the new entry's fields. author John B. Matthews

      • setFileCount

        public void setFileCount​(int count)
        Set the file count in a volume entry. Use only on the volume entry: dir.get(0). author John B. Matthews
