public interface IRelation

Method Summary

Modifier and Type	Method and Description
ArrayList<TAttributeNode>	getAttributes() 每个 relation 包含的 attributes 当它为 base table 时，这些 attributes 的来源有三种可能 1.
String	getRelationName()
int	size()

Method Detail

getAttributes

ArrayList<TAttributeNode> getAttributes()

每个 relation 包含的 attributes 当它为 base table 时，这些 attributes 的来源有三种可能 1. 来自数据库的 metadata，第一次 resolve 时就可以获取，来自 sqlenv 2. 来自 create table ddl，第一次 resolve 时就可以获取，来自 sqlenv 3. 来自 sql script，第二次 resolve 时，来自relation的 referenceAttribute 属性。 第一、二中来源是可靠的来源，attributes应该是完整的，第三种推断自 sql script，attributes很可能是不完整的。

Returns:

getRelationName

String getRelationName()

size

int size()
