Enum Constant Summary

Enum Constants

Enum Constant	Description
Always	Use Zip64 extensions for all entries, even if it is clear it is not required.
AlwaysWithCompatibility	Always use Zip64 extensions for LFH and central directory as Always did, and at the meantime encode the relative offset of LFH and disk number start as needed in CFH as AsNeeded did.
AsNeeded	Use Zip64 extensions for all entries where they are required, don't use them for entries that clearly don't require them.
Never	Don't use Zip64 extensions for any entries.

Method Summary

Modifier and Type	Method	Description
static Zip64Mode	valueOf(String name)	Returns the enum constant of this type with the specified name.
static Zip64Mode[]	values()	Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail

Always

public static final Zip64Mode Always

Use Zip64 extensions for all entries, even if it is clear it is not required.

Never

public static final Zip64Mode Never

Don't use Zip64 extensions for any entries.

This will cause a Zip64RequiredException to be thrown if ZipArchiveOutputStream detects it needs Zip64 support.

AsNeeded

public static final Zip64Mode AsNeeded

Use Zip64 extensions for all entries where they are required, don't use them for entries that clearly don't require them.

AlwaysWithCompatibility

public static final Zip64Mode AlwaysWithCompatibility

Always use Zip64 extensions for LFH and central directory as Always did, and at the meantime encode the relative offset of LFH and disk number start as needed in CFH as AsNeeded did.

This is a compromise for some libraries including 7z and Expand-Archive Powershell utility(and likely Excel).

Method Detail

values

public static Zip64Mode[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (Zip64Mode c : Zip64Mode.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static Zip64Mode valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
