枚举 GeoDistanceType

java.lang.Object

java.lang.Enum<GeoDistanceType>

com.alicloud.openservices.tablestore.model.search.sort.GeoDistanceType

所有已实现的接口:

Serializable, Comparable<GeoDistanceType>

public enum GeoDistanceType
extends Enum<GeoDistanceType>

The model used by the Field of geographical spatial type when calculating distance (default is ARC)

枚举常量概要

枚举常量

枚举常量和说明
ARC Arc (since the earth is curved, this setting can accurately measure distances, but involves a larger amount of computation)
PLANE Consider the earth as a plane and calculate the distance between two points (not precise enough, but with less computation)

方法概要

限定符和类型	方法和说明
static GeoDistanceType	valueOf(String name) 返回带有指定名称的该类型的枚举常量。
static GeoDistanceType[]	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

ARC

public static final GeoDistanceType ARC

Arc (since the earth is curved, this setting can accurately measure distances, but involves a larger amount of computation)

PLANE

public static final GeoDistanceType PLANE

Consider the earth as a plane and calculate the distance between two points (not precise enough, but with less computation)

方法详细资料

values

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