Enum Constant Summary

Enum Constants

Enum Constant	Description
DISCONNECT	If the database state can't be loaded during BoskDriver.initialRoot(java.lang.reflect.Type), use the downstream driver's initial state and proceed in disconnected mode.
FAIL	If the database state can't be loaded during BoskDriver.initialRoot(java.lang.reflect.Type), throw an exception.

Enum Constant Details

DISCONNECT

public static final MongoDriverSettings.InitialDatabaseUnavailableMode DISCONNECT

If the database state can't be loaded during BoskDriver.initialRoot(java.lang.reflect.Type), use the downstream driver's initial state and proceed in disconnected mode. This allows the database and application to be booted in either order, which can simplify repairs and recovery in production, but during development, it can cause confusing behaviour if the database is misconfigured.

In the spirit of making things "just work in production", this is the default, but you might want to consider using FAIL in non-production settings.

FAIL

public static final MongoDriverSettings.InitialDatabaseUnavailableMode FAIL

If the database state can't be loaded during BoskDriver.initialRoot(java.lang.reflect.Type), throw an exception. This is probably the desired "fail fast" behaviour during development, but in production, it creates a boot sequencing dependency between the application and the database.

Method Details

values

public static MongoDriverSettings.InitialDatabaseUnavailableMode[] 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 MongoDriverSettings.InitialDatabaseUnavailableMode 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
