枚举 LogicalTypeFamily

java.lang.Object

java.lang.Enum<LogicalTypeFamily>

org.apache.flink.table.types.logical.LogicalTypeFamily

所有已实现的接口:

Serializable, Comparable<LogicalTypeFamily>

@PublicEvolving
public enum LogicalTypeFamily
extends Enum<LogicalTypeFamily>

An enumeration of logical type families for clustering LogicalTypeRoots into categories.

The enumeration is very close to the SQL standard in terms of naming and completeness. However, it reflects just a subset of the evolving standard and contains some extensions (indicated by EXTENSION).

方法详细资料

values

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