Method Details

values

public static OptionalSupplier.Determinism[] 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 OptionalSupplier.Determinism 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

deterministic

public final boolean deterministic()

Returns true if the presence or absence denoted by this OptionalSupplier.Determinism is deterministic.

Returns:

true if the presence or absence denoted by this OptionalSupplier.Determinism is deterministic

Idempotency:

This method is idempotent and deterministic.

Thread Safety:

This method is safe for concurrent use by multiple threads.
