Method Detail

getFilename

java.lang.String getFilename()

Return the name of this file.

setFilename

void setFilename(java.lang.String filename)

Set the name of this file.

getFiletype

java.lang.String getFiletype()

Return the filetype of this file. This will be OS specific.

setFiletype

void setFiletype(java.lang.String filetype)

Set the filetype.

isLocked

boolean isLocked()

Identify if this file is locked.

setLocked

void setLocked(boolean lock)

Set the lock indicator.

getSize

int getSize()

Compute the size of this file (in bytes).

isDirectory

boolean isDirectory()

Identify if this is a directory file.

isDeleted

boolean isDeleted()

Identify if this file has been deleted.

delete

void delete()

Delete the file.

getFileColumnData

java.util.List getFileColumnData(int displayMode)

Get the standard file column header information. This default implementation is intended only for standard mode. displayMode is specified in FormattedDisk.

getFileData

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.

setFileData

void setFileData(byte[] data)
                 throws DiskFullException

Set file data. This, essentially, is saving data to disk using this file entry.

Throws:

DiskFullException

getSuggestedFilter

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.

getFormattedDisk

FormattedDisk getFormattedDisk()

Get the FormattedDisk associated with this FileEntry. This is useful to interfaces that need to retrieve the associated disk.

getMaximumFilenameLength

int getMaximumFilenameLength()

Return the maximum filename length.

needsAddress

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.

setAddress

void setAddress(int address)

Set the address that this file loads at.

canCompile

boolean canCompile()

Indicates that this filetype can be compiled. Compile is a somewhat arbitrary term, as the code may be assembled. NOTE: The current assumption is that the filetype is AppleSoft. This should be updated to include Integer BASIC, assembly, and potentially other languages.
