Enum FsOutputOption

java.lang.Object
  java.lang.Enum<FsOutputOption>
      de.schlichtherle.truezip.fs.FsOutputOption

All Implemented Interfaces:: Serializable, Comparable<FsOutputOption>

@Immutable public enum FsOutputOption
extends Enum<FsOutputOption>
extends Enum<FsOutputOption>

Defines the potential options for data output operations. Not all options may be supported or available for all operations and certain combinations may even be illegal. It's up to the particular operation to define which options are supported and available. If an option is not supported, it must be silently ignored. If an option is not available, an IOException must be thrown.

Enum Constant Summary
`APPEND` Whether or not the new entry data shall get appended to the existing entry data rather than replacing it entirely.
`CACHE` Whether or not the entry data read by an input socket shall get temporarily cached for subsequent access.
`CREATE_PARENTS` Whether or not any missing parent directory entries shall get created automatically.
`EXCLUSIVE` Whether or not an entry must be exclusively created.

Method Summary
`static FsOutputOption`	`valueOf(String name)` Returns the enum constant of this type with the specified name.
`static FsOutputOption[]`	`values()` Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail

CACHE

public static final FsOutputOption CACHE

Whether or not the entry data read by an input socket shall get temporarily cached for subsequent access. As a desired side effect, caching allows a file system controller to FsController.sync(de.schlichtherle.truezip.util.BitField) the entry data to the backing storage (e.g. a parent file system) while some client is still busy on reading or writing the cached entry data.

CREATE_PARENTS

public static final FsOutputOption CREATE_PARENTS

Whether or not any missing parent directory entries shall get created automatically.

APPEND

public static final FsOutputOption APPEND

Whether or not the new entry data shall get appended to the existing entry data rather than replacing it entirely.

EXCLUSIVE

public static final FsOutputOption EXCLUSIVE

Whether or not an entry must be exclusively created. Not that this is not necessarily atomic, so it can't get used for file locking.

Method Detail

values

public static FsOutputOption[] 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 (FsOutputOption c : FsOutputOption.values())
    System.out.println(c);

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

valueOf

public static FsOutputOption 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
