Enum Constant Detail

READ_ONLY

public static final RandomAccessFileMode READ_ONLY

Mode "r" opens for reading only.

READ_WRITE

public static final RandomAccessFileMode READ_WRITE

Mode "rw" opens for reading and writing.

READ_WRITE_SYNC_ALL

public static final RandomAccessFileMode READ_WRITE_SYNC_ALL

Mode "rws" opens for reading and writing, as with "rw", and also require that every update to the file's content or metadata be written synchronously to the underlying storage device.

Method Detail

values

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

Returns:

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

valueOf

public static RandomAccessFileMode valueOf(java.lang.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:

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

java.lang.NullPointerException - if the argument is null

create

public java.io.RandomAccessFile create(java.io.File file)
                                throws java.io.FileNotFoundException

Creates a random access file stream to read from, and optionally to write to, the file specified by the File argument.

Parameters:

file - the file object

Returns:

a random access file stream

Throws:

java.io.FileNotFoundException - See RandomAccessFile(File, String).

create

public java.io.RandomAccessFile create(java.nio.file.Path file)
                                throws java.io.FileNotFoundException

Creates a random access file stream to read from, and optionally to write to, the file specified by the File argument.

Parameters:

file - the file object

Returns:

a random access file stream

Throws:

java.io.FileNotFoundException - See RandomAccessFile(File, String).

create

public java.io.RandomAccessFile create(java.lang.String file)
                                throws java.io.FileNotFoundException

Creates a random access file stream to read from, and optionally to write to, the file specified by the File argument.

Parameters:

file - the file object

Returns:

a random access file stream

Throws:

java.io.FileNotFoundException - See RandomAccessFile(File, String).

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Enum<RandomAccessFileMode>
