枚举常量概要

枚举常量

枚举常量	说明
FORWARD_ONLY	Requests a scrollable result that is only scrollable forwards.
SCROLL_INSENSITIVE	Requests a scrollable result which is insensitive to changes in the underlying data.
SCROLL_SENSITIVE	Requests a scrollable result which is sensitive to changes in the underlying data.

方法概要

修饰符和类型	方法	说明
boolean	lessThan(ScrollMode other)	Determine if this mode is "less than" the provided mode.
int	toResultSetType()	Get the corresponding JDBC scroll type code constant value.
static ScrollMode	valueOf(String name)	返回带有指定名称的该类型的枚举常量。
static ScrollMode[]	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

FORWARD_ONLY

public static final ScrollMode FORWARD_ONLY

Requests a scrollable result that is only scrollable forwards.

另请参阅:

ResultSet.TYPE_FORWARD_ONLY

SCROLL_SENSITIVE

public static final ScrollMode SCROLL_SENSITIVE

Requests a scrollable result which is sensitive to changes in the underlying data.

另请参阅:

ResultSet.TYPE_SCROLL_SENSITIVE

SCROLL_INSENSITIVE

public static final ScrollMode SCROLL_INSENSITIVE

Requests a scrollable result which is insensitive to changes in the underlying data. Note that since the Hibernate session acts as a cache, you might need to explicitly evict objects, if you need to see changes made by other transactions.

另请参阅:

ResultSet.TYPE_SCROLL_INSENSITIVE

方法详细资料

values

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

toResultSetType

public int toResultSetType()

Get the corresponding JDBC scroll type code constant value.

返回:

the JDBC result set type code

lessThan

public boolean lessThan(ScrollMode other)

Determine if this mode is "less than" the provided mode.

参数:

other - The provided mode

返回:

true if this mode is less than the other.
