Direct Known Subclasses:: CheckedReadOnlySfxDriver

@Immutable public class ReadOnlySfxDriver
extends ZipDriver
extends ZipDriver

An archive driver which reads Self Executable (SFX/EXE) ZIP files, but doesn't support to create or update them because this would spoil the SFX code in its preamble.

Field Detail

SFX_CHARSET

public static final Charset SFX_CHARSET

The character set used in SFX archives by default, which is determined by calling System.getProperty("file.encoding").

Constructor Detail

ReadOnlySfxDriver

public ReadOnlySfxDriver(IOPoolProvider provider)

Method Detail

getPreambled

public final boolean getPreambled()

Description copied from class: ZipDriver

Returns the value of the property preambled. If this is true, then a ZIP file is allowed to contain arbitrary data as its preamble before the actual ZIP file data. Self Extracting Archives typically use a preamble to store the application code that is required to extract the ZIP file contents.

Note that searching for a preamble can seriously degrade the performance if the file is not compatible to the ZIP File Format Specification.

The implementation in the class ZipDriver returns false.

Overrides:: getPreambled in class ZipDriver

Returns:: The value of the property preambled.

newZipOutputShop

protected ZipOutputShop newZipOutputShop(FsModel model,
                                         OutputStream out,
                                         ZipInputShop source)
                                  throws IOException

Overrides:: newZipOutputShop in class ZipDriver

Throws:: IOException
