Enum Constant Detail

Incremental

public static final DataLoader.ClosureEnum Incremental

Document-at-a-time closure.

Each documents is loaded separately into a temporary store, the temporary store is closed against the database, and the results of the closure are transferred to the database.

Batch

public static final DataLoader.ClosureEnum Batch

Set-of-documents-at-a-time closure.

A set of documents are loaded into a temporary store, the temporary store is closed against the database, and the results of the closure are transferred to the database. maintaining closure.

None

public static final DataLoader.ClosureEnum None

Closure is not maintained as documents are loaded.

You can always use the InferenceEngine to (re-)close a database. If explicit statements MAY have been deleted, then you SHOULD first delete all inferences before re-computing the closure.

Method Detail

values

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

Returns:

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

valueOf

public static DataLoader.ClosureEnum 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
