Enum Constant Details

READ_WRITE

public static final TransactionType READ_WRITE

Identifies a read/write transaction. Only one read/write transaction and no exclusive transactions can be associated with a data store at any given point in time. When an read-only transaction is started on a data store, any cursors that were opened earlier but are not in a transaction are invalidated in the sense that any method other than open() will throw StaleCursorException.

READ_ONLY

public static final TransactionType READ_ONLY

Identifies a read-only transaction. Multiple read-only transactions can be associated with a data store at any given time; however, no exclusive transaction can be started while a read-only transaction is active.

Method Details

values

public static TransactionType[] values()

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

Returns:

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

valueOf

public static TransactionType 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
