  • 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[]

    • 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 Details

    • values

      public static Zip64Mode[] values()
      Returns an array containing the constants of this enum type, in the order they are declared.
      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
