# Enum FailureMode

java.lang.Object
java.lang.Enum<FailureMode>
com.codename1.security.shield.FailureMode

All Implemented Interfaces:
  `Comparable<FailureMode>`

public enum FailureMode extends Enum<FailureMode>

What a protected host should do when a token cannot be obtained.

This is deliberately a per-host decision. An app typically wants `CLOSED` on the handful of endpoints that move money or read personal data, and `OPEN` everywhere else, so that a shield service outage degrades one feature rather than bricking the app.

- ## Enum Constant Summary

  Enum Constants
  Enum Constant
  Description
  `CLOSED`
  Refuse to send the request, failing it with a `ShieldException` carrying the reason.
  `OPEN`
  Send the request without a token.

- ## Method Summary

  Modifier and Type
  Method
  Description
  `static FailureMode`
  `valueOf(String name)`
  Returns the enum constant of this type with the specified name.
  `static FailureMode[]`
  `values()`
  Returns an array containing the constants of this enum type, in the order they are declared.

  - ### OPEN

    public static final FailureMode OPEN

    Send the request without a token. The customer's backend still decides what to do with an unattested request; this only means the client does not block it locally.

    This is the default, and it is the only behaviour available when the app was built without the enterprise engine.

  - ### CLOSED

    public static final FailureMode CLOSED
    Refuse to send the request, failing it with a `ShieldException` carrying the reason. Use this only where a false negative is more acceptable than an unattested call, and only after reading `ShieldStatus.isTransient()` -- most token failures are network problems, not compromised devices.

- ## Method Details

  - ### values

    public static FailureMode[] 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 FailureMode 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
