枚举 ElasticsearchType

java.lang.Object

java.lang.Enum<ElasticsearchType>

cloud.agileframework.elasticsearch.types.ElasticsearchType

所有已实现的接口:

Serializable, Comparable<ElasticsearchType>

public enum ElasticsearchType
extends Enum<ElasticsearchType>

Enum for Elasticsearch Data Types.

Each type encapsulates mapping to its corresponding JDBC Type and associated properties.

Where required, an Elasticsearch data type is mapped to the least precise JDBCType that can accurately represent it based on the following:

1. Precision of a JDBCType is taken to be the precision of the corresponding Java type mentioned in the JDBC Spec - Table B-1: JDBC Types Mapped to Java Types
2. Precision of Elasticsearch types is based on Elasticsearch Reference > Mapping > Field datatypes

方法详细资料

values

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

fromJdbcType

public static ElasticsearchType fromJdbcType(JDBCType jdbcType)

fromTypeName

public static ElasticsearchType fromTypeName(String typeName)

Returns the ElasticsearchType for the specified elasticsearch data type name.

fromTypeName

public static ElasticsearchType fromTypeName(String typeName,
                                             boolean errorOnUnknownType)

Parses a specified Elasticsearch type name to determine the corresponding ElasticsearchType

参数:

typeName - The Elasticsearch Type name to parse

errorOnUnknownType - If true, the method throws an UnrecognizedElasticsearchTypeException if the type name specified is not recognized.

返回:
