枚举常量概要

枚举常量

枚举常量	说明
NONSTRICT_READ_WRITE	Read and write access (non-strict).
READ_ONLY	Read-only access.
READ_WRITE	Read and write access (strict).
TRANSACTIONAL	A read and write strategy where isolation/locking is maintained in conjunction with a JTA transaction.

方法概要

修饰符和类型	方法	说明
static AccessType	fromExternalName(String externalName)	Resolve an AccessType from its external name.
String	getExternalName()	Get the corresponding externalized name for this value.
String	toString()
static AccessType	valueOf(String name)	返回带有指定名称的该类型的枚举常量。
static AccessType[]	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。

枚举常量详细资料

READ_ONLY

public static final AccessType READ_ONLY

Read-only access. Data may be added and removed, but not mutated.

READ_WRITE

public static final AccessType READ_WRITE

Read and write access (strict). Data may be added, removed and mutated.

NONSTRICT_READ_WRITE

public static final AccessType NONSTRICT_READ_WRITE

Read and write access (non-strict). Data may be added, removed and mutated. The non-strictness comes from the fact that locks are not maintained as tightly as in READ_WRITE, which leads to better throughput but may also lead to inconsistencies.

TRANSACTIONAL

public static final AccessType TRANSACTIONAL

A read and write strategy where isolation/locking is maintained in conjunction with a JTA transaction.

方法详细资料

values

public static AccessType[] 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 (AccessType c : AccessType.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 AccessType 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

getExternalName

public String getExternalName()

Get the corresponding externalized name for this value.

返回:

The corresponding externalized name.

toString

public String toString()

覆盖:

toString 在类中 Enum<AccessType>

fromExternalName

public static AccessType fromExternalName(String externalName)

Resolve an AccessType from its external name.

参数:

externalName - The external representation to resolve

返回:

The access type.

抛出:

UnknownAccessTypeException - If the externalName was not recognized.
