枚举常量概要

枚举常量

枚举常量	说明
ROWID_UNSUPPORTED	Indicates that this data source does not support the ROWID type.
ROWID_VALID_FOREVER	Indicates that the lifetime of a RowId from this data source is, effectively, unlimited.
ROWID_VALID_OTHER	Indicates that the lifetime of a RowId from this data source is indeterminate; but not one of ROWID_VALID_TRANSACTION, ROWID_VALID_SESSION, or, ROWID_VALID_FOREVER.
ROWID_VALID_SESSION	Indicates that the lifetime of a RowId from this data source is at least the containing session.
ROWID_VALID_TRANSACTION	Indicates that the lifetime of a RowId from this data source is at least the containing transaction.

方法概要

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

枚举常量详细资料

ROWID_UNSUPPORTED

public static final RowIdLifetime ROWID_UNSUPPORTED

Indicates that this data source does not support the ROWID type.

ROWID_VALID_OTHER

public static final RowIdLifetime ROWID_VALID_OTHER

Indicates that the lifetime of a RowId from this data source is indeterminate; but not one of ROWID_VALID_TRANSACTION, ROWID_VALID_SESSION, or, ROWID_VALID_FOREVER.

ROWID_VALID_SESSION

public static final RowIdLifetime ROWID_VALID_SESSION

Indicates that the lifetime of a RowId from this data source is at least the containing session.

ROWID_VALID_TRANSACTION

public static final RowIdLifetime ROWID_VALID_TRANSACTION

Indicates that the lifetime of a RowId from this data source is at least the containing transaction.

ROWID_VALID_FOREVER

public static final RowIdLifetime ROWID_VALID_FOREVER

Indicates that the lifetime of a RowId from this data source is, effectively, unlimited.

方法详细资料

values

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