Enum FillRule

java.lang.Object

java.lang.Enum<FillRule>

app.myoss.cloud.mybatis.table.annotation.FillRule

All Implemented Interfaces:

Serializable, Comparable<FillRule>

public enum FillRule
extends Enum<FillRule>

用于 SQL 语句在 INSERT/UPDATE 的时候，字段是否需要进行填充，因为生成 Mybatis SQL 语句的时候默认会使用 <if test="id != null"> 这种表达式判断，需要提前标记字段是否不需要 if 表达式进行包装，需要配合 ParameterHandlerCustomizer 进行设置值。

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
