Enum Constant Detail

INSERT_ONLY

public static final WriteMode INSERT_ONLY

Items will be inserted to MongoDB; in case of ID clash, error will be thrown.

UPDATE_ONLY

public static final WriteMode UPDATE_ONLY

Performs update. Entity with the given _id must already exist, otherwise an error will be thrown.

UPSERT

public static final WriteMode UPSERT

Performs update. If the entity with the given _id does not exist, it will be created.

REPLACE

public static final WriteMode REPLACE

Performs replace. If the entity with the given _id does not exist, it will be created (if it was not overridden by the user).

Replace is different from UPSERT in handling of missing fields. Replace will set them to null, while upsert won't affect such fields in the entity.

Method Detail

values

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

Returns:

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

valueOf

public static WriteMode 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
