Enum Constant Detail

MEMORY_MAPPED

public static final Reader.FileMode MEMORY_MAPPED

The default file mode. This maps the database to virtual memory. This often provides similar performance to loading the database into real memory without the overhead.

MEMORY

public static final Reader.FileMode MEMORY

Loads the database into memory when the reader is constructed.

Method Detail

values

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

Returns:

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

valueOf

public static Reader.FileMode 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
