枚举 BiometricAuthentication.SecureLevel

java.lang.Object

java.lang.Enum<BiometricAuthentication.SecureLevel>

ohos.biometrics.authentication.BiometricAuthentication.SecureLevel

所有已实现的接口:

Serializable, Comparable<BiometricAuthentication.SecureLevel>

封闭类:

BiometricAuthentication

public static enum BiometricAuthentication.SecureLevel
extends Enum<BiometricAuthentication.SecureLevel>

Indicates the security level of the data to access.

Currently, biometric authentication provides 3D facial authentication (the highest security level supported is S3) and 2D facial authentication (the highest security level supported is S2). S4 is not supported in the current version. Applications can choose the appropriate security level based on the security requirements for the data to access. If the authentication security capability of the device is higher than or equal to the security level required by the application, biometric authentication is supported; if the authentication security capability of the device is lower than the security level required by the application, biometric authentication is not supported. This enumeration is used as a parameter in BiometricAuthentication.checkAuthenticationAvailability(ohos.biometrics.authentication.BiometricAuthentication.AuthType,ohos.biometrics.authentication.BiometricAuthentication.SecureLevel,boolean) and BiometricAuthentication.execAuthenticationAction(ohos.biometrics.authentication.BiometricAuthentication.AuthType,ohos.biometrics.authentication.BiometricAuthentication.SecureLevel,boolean,boolean,ohos.biometrics.authentication.BiometricAuthentication.SystemAuthDialogInfo).

枚举常量概要

枚举常量

枚举常量	说明
SECURE_LEVEL_S1	Indicates the low security level.
SECURE_LEVEL_S2	Indicates the medium security level.
SECURE_LEVEL_S3	Indicates the high security level.
SECURE_LEVEL_S4	Indicates the highest security level.

方法概要

限定符和类型	方法	说明
static BiometricAuthentication.SecureLevel	valueOf(String name)	返回带有指定名称的该类型的枚举常量。 字符串必须与用于声明该类型的枚举常量的 标识符完全匹配。(不允许有多余 的空格字符。)
static BiometricAuthentication.SecureLevel[]	values()	按照声明该枚举类型的常量的顺序, 返回 包含这些常量的数组。该方法可用于迭代 常量, 如下所示: for (BiometricAuthentication.SecureLevel c : BiometricAuthentication.SecureLevel.values()) System.out.println(c);

方法详细资料

values

public static BiometricAuthentication.SecureLevel[] values()

按照声明该枚举类型的常量的顺序, 返回 包含这些常量的数组。该方法可用于迭代 常量, 如下所示:

for (BiometricAuthentication.SecureLevel c : BiometricAuthentication.SecureLevel.values())
    System.out.println(c);

返回:

按照声明该枚举类型的常量的顺序返回的包含这些常量的数组

valueOf

public static BiometricAuthentication.SecureLevel valueOf(String name)

返回带有指定名称的该类型的枚举常量。 字符串必须与用于声明该类型的枚举常量的 标识符完全匹配。(不允许有多余 的空格字符。)

参数:

name - 要返回的枚举常量的名称。

返回:

返回带有指定名称的枚举常量

抛出:

IllegalArgumentException - 如果该枚举类型没有带有指定名称的常量

NullPointerException - 如果参数为空值
