      public void setLocked(boolean lock)
      Set the lock indicator.
      Specified by:
      setLocked in interface FileEntry

    • getSize

      public int getSize()
      Compute the size of this file (in bytes).
      Specified by:
      getSize in interface FileEntry
      See Also:

      public void setSectorsUsed(int sectorsUsed)
      Set the number of sectors used.

    • isDirectory

      public boolean isDirectory()
      Identify if this is a directory file.
      Specified by:
      isDirectory in interface FileEntry
      See Also:

    • isDeleted

      public boolean isDeleted()
      Identify if this file has been deleted.
      Specified by:
      isDeleted in interface FileEntry
      See Also:

    • delete

      public void delete()
      Delete this file.
      Specified by:
      delete in interface FileEntry

    • getFileColumnData

      public List<String> getFileColumnData(int displayMode)
      Get the standard file column header information. This default implementation is intended only for standard mode. displayMode is specified in FormattedDisk.
      Specified by:
      getFileColumnData in interface FileEntry

    • getTrack

      public int getTrack()
      Get the track of first track/sector list sector.

    • setTrack

      public void setTrack(int track)
      Set the track of the first track/sector list sector.

    • getSector

      public int getSector()
      Get the sector of first track/sector list sector.

    • setSector

      public void setSector(int sector)
      Set the sector of the first track/sector list sector.

    • getFileData

      public byte[] getFileData()
      Get file data. This handles any operating-system specific issues. Specifically, DOS 3.3 places address and length into binary files and length into Applesoft files.
      Specified by:
      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. Note: The address can be set before the data is saved or after the data is saved. This is an attempt to make the API more easily usable. Empirically, the data must be set before the address is set.
      Specified by:
      setFileData in interface FileEntry
      Throws:
      DiskFullException

    • 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

    • isAssemblySourceFile

      public boolean isAssemblySourceFile()
      Determine if this is an assembly source code file.

    • isTextFile

      public boolean isTextFile()
      Determine if this is a text file.

    • isApplesoftBasicFile

      public boolean isApplesoftBasicFile()
      Determine if this is an Applesoft BASIC file.

    • isIntegerBasicFile

      public boolean isIntegerBasicFile()
      Determine if this is an Integer BASIC file.

    • isBinaryFile

      public boolean isBinaryFile()
      Determine if this is a binary file.

    • getFormattedDisk

      public FormattedDisk getFormattedDisk()
      Get the FormattedDisk associated with this FileEntry. This is useful to interfaces that need to retrieve the associated disk.
      Specified by:
      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.
      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

    • getAddress

      public int getAddress()
      Get the address that this file loads at.
      Specified by:
      getAddress in interface FileEntry
