TTableFunction

public TTableFunction()

Method Detail

size

public int size()

Specified by:

size in interface IRelation

getAttributes

public ArrayList<TAttributeNode> getAttributes()

Description copied from interface: IRelation

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。

Specified by:

getAttributes in interface IRelation

Returns:

getRelationName

public String getRelationName()

Specified by:

getRelationName in interface IRelation

initAttributes

public void initAttributes()

init

public void init(Object arg1,
                 Object arg2,
                 Object arg3)

Overrides:

init in class TFunctionCall

init

public void init(Object arg1,
                 Object arg2,

Overrides:

init in class TFunctionCall

doParse

public void doParse(TCustomSqlStatement psql,
                    ESqlClause plocation)

Description copied from class: TParseTreeNode

Parameters:

v - visitor is a descendant class of TParseTreeVisitor

acceptChildren

Specified by:

acceptChildren in interface Visitable

Overrides:

acceptChildren in class TFunctionCall

Parameters:

v - visitor is a descendant class of TParseTreeVisitor
