接口 TypeMetadata

所有已知实现类:

AbstractTypeMetadata, StandardTypeMetadata

public interface TypeMetadata

嵌套类概要

嵌套类

限定符和类型	接口和说明
static class	TypeMetadata.CATEGORY
static class	TypeMetadata.CATEGORY_GROUP CATEGORY主要是对数据库中数据类型的归类主要用亚区分 length/precision/scale,如text类型不需要length而varchar类型需要 CATEGORY_GROUP是对CATEGORY的进一步归类，更接近Java类型
static class	TypeMetadata.Refer
