Method Details

readEntry

public DataBuffer readEntry()

modifyEntry

public void modifyEntry(Consumer<DataBuffer> consumer)

getFileStore

public PascalFileStore getFileStore()

Returns the FileStore that this Directory belongs to.

Specified by:

getFileStore in interface Directory

getName

public String getName()

Returns the name of this directory.

Specified by:

getName in interface Directory

setName

public void setName(String name)

Sets the name of this directory. Per the Apple Pascal documentation:

A diskette's volume name must be seven or fewer characters long and may not contain an equals sign (=), dollar sign ($), question mark (?) or comma(,).

This method only errors if, after applying the rules, the string is empty.

getBlocksOnDisk

public int getBlocksOnDisk()

getFilesOnDisk

public int getFilesOnDisk()

updateFilesOnDisk

public void updateFilesOnDisk(int modifier)

getMostRecentDate

public Date getMostRecentDate()

setMostRecentDate

public void setMostRecentDate(Date date)

getFiles

public List<FileEntry> getFiles()

Return all entries that are stored in this directory.

Specified by:

getFiles in interface Directory

createFile

public PascalFileEntry createFile(String fileName)

Create a file. By definition, any file created is a WritableFileEntry.

Specified by:

createFile in interface WritableDirectory

See Also:

• Capability.CREATE_FILES

createFrom

public PascalFileEntry createFrom(ProdosAttributes prodosAttributes)

Create a file given the supplied ProDOS attributes. This is expected to handle setting all appropriate FileEntry attributes that align. File type should be converted, dates applied, etc.

Specified by:

createFrom in interface WritableDirectory

See Also:

• Capability.CREATE_FILES

deleteFile

public void deleteFile(FileEntry fileEntry)

Delete a Pascal file. Pascal does not mark a file as delete, it simply removes the entry. This logic copies all data after into this position. Note that, regardless, any existing PascalFileEntry objects are invalid since their offset will be incorrect.

Specified by:

deleteFile in interface WritableDirectory

See Also:

• Capability.DELETE_FILES
