Enum Constant Detail

TRY_RESOLVE

public static final OptimizerConfigOptions.NonDeterministicUpdateStrategy TRY_RESOLVE

Try to resolve by planner automatically if exists non-deterministic updates, will raise an error when cannot resolve.

IGNORE

public static final OptimizerConfigOptions.NonDeterministicUpdateStrategy IGNORE

Do nothing if exists non-deterministic updates, the risk of wrong result still exists.

Method Detail

values

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

Returns:

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

valueOf

public static OptimizerConfigOptions.NonDeterministicUpdateStrategy 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
