枚举常量概要

枚举常量

枚举常量	说明
DIFFERENCE	Indicates an operation to obtain the part of the current region, which is different from the target region.
INTERSECT	Indicates an operation to obtain the part where the current region intersects the target region.
REPLACE	Indicates an operation to replace the current region with the target region.
REVERSE_DIFFERENCE	Obtains the part of the target region, which is different from the current region.
UNION	Indicates an operation to obtain the union of the current region and the target region.
XOR	Indicates an operation to obtain the union of the current region and the target region, with the intersection between the two removed.

方法概要

限定符和类型	方法	说明
int	value()	Obtains the enumeration identifier of the region operation type.
static Region.Op	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 Region.Op[]	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 (Region.Op c : Region.Op.values()) System.out.println(c);

枚举常量详细资料

DIFFERENCE

public static final Region.Op DIFFERENCE

Indicates an operation to obtain the part of the current region, which is different from the target region.

INTERSECT

public static final Region.Op INTERSECT

Indicates an operation to obtain the part where the current region intersects the target region.

UNION

public static final Region.Op UNION

Indicates an operation to obtain the union of the current region and the target region.

XOR

public static final Region.Op XOR

Indicates an operation to obtain the union of the current region and the target region, with the intersection between the two removed.

REVERSE_DIFFERENCE

public static final Region.Op REVERSE_DIFFERENCE

Obtains the part of the target region, which is different from the current region.

REPLACE

public static final Region.Op REPLACE

Indicates an operation to replace the current region with the target region.

方法详细资料

values

public static Region.Op[] 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 (Region.Op c : Region.Op.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 Region.Op 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

value

public int value()

Obtains the enumeration identifier of the region operation type.

返回:

Returns the enumeration identifier of the region operation type.
