枚举常量概要

枚举常量

枚举常量	说明
NONE	Indicates no concurrency strategy should be applied.
NONSTRICT_READ_WRITE	Indicates that the non-strict read-write strategy should be applied.
READ_ONLY	Indicates that read-only strategy should be applied.
READ_WRITE	Indicates that the read-write strategy should be applied.
TRANSACTIONAL	Indicates that the transaction strategy should be applied.

方法概要

修饰符和类型	方法	说明
static CacheConcurrencyStrategy	fromAccessType(AccessType accessType)	Conversion from AccessType to CacheConcurrencyStrategy.
static CacheConcurrencyStrategy	parse(String name)	Parse an external representation of a CacheConcurrencyStrategy value.
AccessType	toAccessType()	Get the AccessType corresponding to this concurrency strategy.
static CacheConcurrencyStrategy	valueOf(String name)	返回带有指定名称的该类型的枚举常量。
static CacheConcurrencyStrategy[]	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

NONE

public static final CacheConcurrencyStrategy NONE

Indicates no concurrency strategy should be applied.

READ_ONLY

public static final CacheConcurrencyStrategy READ_ONLY

Indicates that read-only strategy should be applied.

另请参阅:

AccessType.READ_ONLY

NONSTRICT_READ_WRITE

public static final CacheConcurrencyStrategy NONSTRICT_READ_WRITE

Indicates that the non-strict read-write strategy should be applied.

另请参阅:

AccessType.NONSTRICT_READ_WRITE

READ_WRITE

public static final CacheConcurrencyStrategy READ_WRITE

Indicates that the read-write strategy should be applied.

另请参阅:

AccessType.READ_WRITE

TRANSACTIONAL

public static final CacheConcurrencyStrategy TRANSACTIONAL

Indicates that the transaction strategy should be applied.

另请参阅:

AccessType.TRANSACTIONAL

方法详细资料

values

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

toAccessType

public AccessType toAccessType()

Get the AccessType corresponding to this concurrency strategy.

返回:

The corresponding concurrency strategy. Note that this will return null for NONE

fromAccessType

public static CacheConcurrencyStrategy fromAccessType(AccessType accessType)

Conversion from AccessType to CacheConcurrencyStrategy.

参数:

accessType - The access type to convert

返回:

The corresponding enum value. NONE is returned by default if unable to recognize accessType or if accessType is null.

parse

public static CacheConcurrencyStrategy parse(String name)

Parse an external representation of a CacheConcurrencyStrategy value.

参数:

name - The external representation

返回:

The corresponding enum value, or null if not match was found.
