枚举 BiometricAuthentication.AuthType

java.lang.Object

java.lang.Enum<BiometricAuthentication.AuthType>

ohos.biometrics.authentication.BiometricAuthentication.AuthType

所有已实现的接口:

Serializable, Comparable<BiometricAuthentication.AuthType>

封闭类:

BiometricAuthentication

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

Indicates the authentication type.

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
AUTH_TYPE_BIOMETRIC_ALL	Indicates that any supported biometric information of the device (such as facial image and fingerprint) can be used for authentication.
AUTH_TYPE_BIOMETRIC_FACE_ONLY	Indicates that only the human face is used for authentication.
AUTH_TYPE_BIOMETRIC_FINGERPRINT_ONLY	Indicates that only the fingerprint is used for authentication.

方法概要

限定符和类型	方法	说明
static BiometricAuthentication.AuthType	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.AuthType[]	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.AuthType c : BiometricAuthentication.AuthType.values()) System.out.println(c);

枚举常量详细资料

AUTH_TYPE_BIOMETRIC_ALL

public static final BiometricAuthentication.AuthType AUTH_TYPE_BIOMETRIC_ALL

Indicates that any supported biometric information of the device (such as facial image and fingerprint) can be used for authentication. It is not supported in the current version.

AUTH_TYPE_BIOMETRIC_FINGERPRINT_ONLY

public static final BiometricAuthentication.AuthType AUTH_TYPE_BIOMETRIC_FINGERPRINT_ONLY

Indicates that only the fingerprint is used for authentication. It is not supported in the current version.

AUTH_TYPE_BIOMETRIC_FACE_ONLY

public static final BiometricAuthentication.AuthType AUTH_TYPE_BIOMETRIC_FACE_ONLY

Indicates that only the human face is used for authentication.

方法详细资料

values

public static BiometricAuthentication.AuthType[] 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.AuthType c : BiometricAuthentication.AuthType.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.AuthType 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
