Enum Constant Details

BACKEND

public static final ConsistencyScope BACKEND

Every table read through the transaction reflects one single instant.

TABLE

public static final ConsistencyScope TABLE

The caller only needs each table to be internally consistent. Backends may use a cheaper mechanism (e.g., skipping snapshot export), and may report the weaker guarantee.

Method Details

values

public static ConsistencyScope[] values()

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

Returns:

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

valueOf

public static ConsistencyScope valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (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 class has no constant with the specified name

NullPointerException - if the argument is null
