ColumnType (AliCloud TableStore SDK for Java 5.17.7 API)

java.lang.Object
- java.lang.Enum<ColumnType>
- - com.alicloud.openservices.tablestore.model.ColumnType

所有已实现的接口:

Serializable, Comparable<ColumnType>
```
public enum ColumnType
extends Enum<ColumnType>
```
Indicates the data types of attribute columns. Currently, only five data types are supported: STRING, INTEGER, BINARY, DOUBLE, and BOOLEAN.

枚举常量概要

枚举常量
枚举常量和说明
`BINARY` Binary data.
`BOOLEAN` Boolean type.
`DATE` Date type, formatted as 'YYYY-MM-DD', represented by the java.sql.Date type.
`DATETIME` Time type, formatted as 'YYYY-MM-DD hh:mm:ss.xxxxxx', represented by the java.sql.Timestamp type.
`DOUBLE` 64-bit double-precision floating-point type.
`INTEGER` 64-bit signed integer.
`STRING` String type.
`TIME` Time interval type, formatted as 'hh:mm:ss.xxxxxx', represented using the java.sql.Time type.

方法概要

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

  - values
```
public static ColumnType[] 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 (ColumnType c : ColumnType.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 ColumnType 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
